CATL Shares Details Of Next Generation 5C Battery - CleanTechnica
CATL has unveiled details of its next-generation 5C battery, which significantly advances rapid charging and battery longevity for electric vehicles (EVs). The 5C rating means the battery can theoretically be charged at five times its capacity rate, enabling a full charge in about 12 minutes with a 400 kW charger, compared to the typical slower charging rates currently experienced. This new battery reportedly offers about six times the life expectancy of current industry averages, potentially outlasting the vehicle itself. Under extreme heat conditions (60°C), it maintains 80% capacity after 1,400 cycles, equivalent to roughly 840,000 kilometers, far surpassing conventional lithium-ion cells. CATL attributes these improvements to three key innovations: a denser and more uniform cathode coating that reduces structural degradation, a proprietary electrolyte additive that repairs micro-cracks and reduces lithium loss, and a temperature-responsive coating on the separator that slows ion migration to prevent thermal runaway. Additionally, an upgraded cooling system targets hot spots

A research team at South Korea’s Ulsan National Institute of Science and Technology (UNIST), led by Professor Kyeong Min Jeong, has developed a novel thick electrode design that significantly enhances electric vehicle (EV) battery performance by increasing power output by approximately 75% without sacrificing energy storage capacity. This breakthrough addresses the common tradeoff in battery design where thicker electrodes, while storing more charge and extending driving range, typically suffer from reduced power output due to slower lithium-ion transport through the electrode’s interior. By optimizing the internal pore structure—specifically balancing large pores and the carbon-binder domain (CBD) micropores—the team created faster ion pathways that maintain electronic conductivity, enabling both high areal capacity and strong, responsive power delivery during demanding conditions like rapid acceleration. The researchers introduced a new analytical framework called the Dual-Pore Transmission Line Model (DTLM), which more accurately represents ion transport through two distinct pore pathways rather than averaging porosity as a single value. This model links electrical

Researchers at the Korea Research Institute of Standards and Science (KRISS) have developed a breakthrough material technology that significantly advances the commercialization of all-solid-state batteries (ASSBs). ASSBs replace the flammable liquid electrolytes used in conventional lithium-ion batteries with non-flammable solid electrolytes, greatly enhancing battery safety by eliminating fire and explosion risks. This innovation addresses long-standing challenges in the fabrication of oxide-based ASSBs, which use garnet-type solid electrolytes known for their high ionic conductivity and chemical stability but require costly, high-temperature sintering processes. The team overcame a major production barrier by creating a novel fabrication method that involves thinly coating solid electrolyte powders with lithium–aluminum–oxide (Li–Al–O) multifunctional compounds. This coating supplies lithium during sintering, prevents lithium evaporation, and improves particle bonding, resulting in electrolyte membranes with a record-high density exceeding 98.2%. Unlike conventional methods that discard large amounts of expensive lithium-containing "mother powder," this approach eliminates the

Stanford University researchers have developed a method to significantly improve the mechanical durability of ceramic electrolytes used in solid-state batteries, addressing their inherent brittleness that leads to cracking and battery failure. By applying an ultra-thin, 3-nanometer silver coating onto the lithium lanthanum zirconium oxide (LLZO) electrolyte and annealing it at 300°C, silver ions diffuse into the electrolyte, replacing smaller lithium ions and creating a positively charged structural barrier. This nanoscale silver doping enhances fracture resistance by nearly five times and prevents lithium from wedging into microscopic surface cracks, which typically expand during fast charging and cause destructive fissures. The study highlights that this silver ion diffusion fundamentally changes how cracks initiate and propagate, making the electrolyte more stable under extreme electrochemical and mechanical conditions. While other ions like copper showed some effectiveness, silver remains the most efficient for this purpose. The team is now scaling up from small samples to full battery cells to test the coating’s durability over thousands of charge cycles,

The article discusses a recent report from the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) highlighting the economic and operational benefits of integrating battery energy storage systems (BESS) with hydropower facilities. This development follows the Trump administration’s 2020 declaration of an “energy emergency,” which granted preferential status to hydropower alongside fossil fuels. The PNNL report emphasizes that even short-duration lithium-ion batteries—such as a 60-megawatt system with two hours of storage—can significantly enhance hydropower’s flexibility and revenue potential by storing excess electricity during low demand periods. Hydropower plants face challenges adapting to the modern grid’s dynamic demands because their turbines, designed in the 20th century, suffer wear and tear from frequent start-stop cycles. While operators can inject compressed air to keep turbines spinning without generating power, this method is limited by downstream water conditions and risks equipment damage. The addition of battery storage offers a practical solution: turbines can continue

A research team from Harbin Institute of Technology, led by Professors Yan Zhang and Shuaifeng Lou, has developed a crystallographic engineering approach to enhance lithium-ion battery performance at sub-zero temperatures. Focusing on titanium niobate (TiNb₂O₇, TNO), a promising anode material known for its safety and structural stability but limited by poor electronic conductivity and slow lithium-ion diffusion, the team introduced dual-element doping with antimony (Sb⁵⁺) and niobium (Nb⁵⁺). This doping, achieved via a single-step solid-state synthesis compatible with industrial processes, fundamentally improved ion and electron transport within the TNO lattice, enabling fast charging and long battery life even at −30 °C. The doped TNO exhibited a reversible phase transformation mechanism during cycling and maintained mechanical integrity after 500 charge-discharge cycles at low temperature, as confirmed by in-situ X-ray diffraction and synchrotron-based nano-computed tomography.

The article discusses the recently enacted Massachusetts law mandating the installation of 5,000 MW of battery storage capacity by 2030, with a focus on the complexities surrounding the energy storage duration requirements. While an initial 1,500 MW tender specified a minimum of 4 hours duration (implying about 5,072 MWh of energy storage), the broader law categorizes the battery systems into three duration groups: 3,500 MW with 4-10 hours, 750 MW with 10-24 hours, and 750 MW with at least 24 hours. This translates to a minimum total energy storage capacity of approximately 39,500 MWh, a significant increase over typical lithium-ion battery deployments which generally offer up to 4 hours duration. Given the ambitious duration requirements—especially the 10-24 hour and 24+ hour segments—the article suggests lithium-ion technology alone is unlikely to meet these targets by 2030. Instead, it highlights the potential of alternative

China is conducting advanced experiments aboard its Tiangong space station to study the effects of microgravity on lithium-ion battery behavior, aiming to develop safer and more powerful batteries for space applications. Zhang Hongzhang, a professor specializing in advanced battery technologies from the Dalian Institute of Chemical Physics and China’s second civilian astronaut, is leading these tests during the Shenzhou-21 mission launched in October 2025. His research focuses on how microgravity influences key battery processes such as ion movement between electrodes, electrolyte chemical distribution, and the formation of lithium dendrites—needle-like structures that can reduce battery lifespan and pose safety risks. By leveraging the unique microgravity environment aboard Tiangong, Zhang’s experiments seek to isolate the impact of gravity on battery performance, which is difficult to study on Earth due to the interplay of gravitational and electric fields. The findings are expected to enhance the safety and efficiency of current lithium-ion batteries used in orbit and contribute to the development of next-generation batteries with higher energy density

Researchers at Gyeongsang National University in Korea have developed a novel approach to structural lithium-ion batteries (LIBs) by growing carbon nanotubes (CNTs) on quartz-woven fabrics (QWFs) to serve as multifunctional electrodes. This innovation addresses a key challenge in LIB design: creating batteries that not only store energy efficiently but also bear mechanical loads, thereby reducing weight and improving safety. Traditional LIBs add significant weight without contributing structurally, which is a limitation especially in aerospace and electric vehicle (EV) applications where efficiency is critical. Quartz-woven fabrics offer excellent dimensional stability, chemical inertness, and thermal resistance but lack electrical conductivity, which the CNTs effectively provide by forming electron transport networks and reinforcing the electrode matrix. Using a chemical vapor deposition (CVD) method with nickel catalysts, the researchers achieved uniform CNT growth on QWFs, optimizing the process at two temperatures (600°C and 700°C). The sample grown at 700°C (C-QWF-

Researchers from Argonne National Laboratory and the University of Chicago have uncovered the underlying cause of degradation in single-crystal nickel-rich lithium-ion cathodes used in electric vehicle (EV) batteries. While single-crystal cathodes were initially expected to outperform traditional polycrystalline cathodes by avoiding grain boundary-related cracking, they still exhibited unexpected cracking and performance fade. Using advanced synchrotron X-ray and electron microscopy techniques, the team discovered that reaction heterogeneity within single-crystal particles causes internal strain, leading to nanoscale fractures from within the particles, a degradation mechanism distinct from that in polycrystalline materials. This insight challenges previous assumptions and conventional design principles that were based on polycrystalline cathodes. Notably, the study found that cobalt, which in polycrystalline cathodes tends to promote cracking but prevents structural disorder, actually improves durability in single-crystal cathodes, whereas manganese causes more mechanical damage. These findings suggest that new design strategies and material compositions are necessary to enhance battery longevity and safety.

Researchers at Tohoku University have developed a breakthrough in lithium-ion battery anode technology by stabilizing fullerene (C60) molecules through a covalently bridged framework called Mg4C60. This novel material uses magnesium atoms to create strong intercage connections, transforming the fullerene from a fragile molecular solid into a robust layered polymeric structure. This design prevents the dissolution and structural collapse that previously limited fullerene use in batteries, enabling reversible lithium storage without degradation. Unlike graphite anodes, which face limitations such as slow charging rates and lithium plating risks, Mg4C60 offers a stable alternative that could support ultra-fast charging and higher energy density. The study demonstrates that the Mg4C60 framework maintains its integrity during lithium insertion and extraction, showing electrochemical behavior similar to soft carbon but with enhanced stability. This advancement points to longer battery lifetimes and improved safety, with potential applications in electric vehicles, consumer electronics, and renewable energy storage. The research team plans to extend this covalent

Researchers at POSTECH, led by Professor Won Bae Kim, have developed a novel "dream battery" technology that significantly enhances energy storage capacity for electric vehicles (EVs) while improving safety. This new system employs a magneto-conversion strategy using an external magnetic field to control lithium-ion transport within ferromagnetic manganese ferrite anodes. By aligning ferromagnetic nanoparticles under the magnetic field, the technology prevents the formation of hazardous lithium dendrites—needle-like structures that cause short circuits and thermal runaway in conventional lithium metal batteries. As a result, the battery achieves four times the energy capacity of commercial graphite anodes and maintains a Coulombic efficiency above 99% over more than 300 cycles. The innovation addresses two major challenges in lithium metal batteries: dendrite growth and structural instability. The magnetic field ensures a smooth, dense lithium deposition layer that remains stable through extensive charge-discharge cycles, avoiding the degradation that typically limits battery lifespan.

Researchers from China’s Nankai University have developed a novel method to mitigate voltage fade in lithium-rich layered oxide (LRLO) cathodes, a promising material for next-generation lithium-ion batteries used in electric vehicles and grid storage. Voltage fade, a major challenge in these high-energy batteries, results from structural instability, transition-metal migration, and oxygen loss during high-voltage cycling. The team introduced trace amounts (sub-1 atomic percent) of tungsten (W⁶⁺) dopants into tetrahedral interstitial sites within the cathode’s crystal lattice—an unconventional doping site compared to the typical octahedral positions. Advanced imaging techniques confirmed tungsten’s unique placement, which exerts long-range Coulomb repulsion that suppresses transition-metal migration and stabilizes the structure over a region much larger than typical atomic-scale effects. This tetrahedral-site doping significantly reduces lattice strain and prevents oxygen vacancy formation and oxygen release, key factors that trigger voltage fade. Experimental results showed that tungsten-doped cathodes

The article discusses the safety risks associated with solid-state batteries, which are often promoted as a safer alternative to traditional liquid lithium-ion batteries. Despite replacing liquid electrolytes with solid ones, experts caution that solid-state batteries still carry significant fire and thermal runaway risks due to their high energy density and the reactive nature of lithium metal, especially in designs using lithium metal anodes. Experimental findings indicate that lithium metal can react with cathode materials even without oxygen, potentially causing extreme aluminothermic reactions at very high temperatures. Thus, safety challenges remain and must be addressed through careful materials engineering, cell design, and manufacturing controls rather than assuming inherent safety. In China, momentum is growing to commercialize solid-state batteries in the automotive sector, with companies like FAW Group planning to introduce these batteries in vehicles by 2027 and others initiating pilot production for testing. However, some analysts warn against viewing solid-state batteries as a guaranteed solution to fire risks, noting that liquid lithium-ion batteries continue to improve in safety through innovations

An international research team from SLAC National Accelerator Laboratory and the Korea Institute of Science and Technology has developed a method to extend lithium-ion battery lifespan by preventing a key structural failure in nickel-rich cathodes called c-collapse. This failure occurs due to sudden lattice contraction during high-voltage cycling, causing particle cracking and reduced battery life. Instead of maintaining a perfectly ordered crystal structure, the scientists introduced controlled atomic disorder through an electrochemical activation process, transforming the cathode into a disordered layered (DL) structure. This new imperfect crystal arrangement reduces anisotropic strain, thereby enhancing both capacity and cycle life. The researchers demonstrated their approach using a high-energy nickel-rich material, LiNi₀.₉Mn₀.₁O₂, closely related to commercial cathodes. Batteries with the modified cathodes retained high energy capacity and showed improved structural stability during repeated charge-discharge cycles by preventing sharp lattice contraction. The electrochemical tuning method reduces internal strain, limits particle cracking, and suppresses voltage loss

Dallas-based Solidion Technology has developed a silicon-rich, high-capacity anode for lithium-ion batteries that could extend drone flying ranges and electric vehicle (EV) driving distances by up to 45%. This innovation uses a flexible rubber matrix to incorporate silicon into the anode with a spherical morphology, enhancing structural integrity and lithium-ion utilization for improved energy output. The anode combines a graphene-silicon composite with various forms of graphite, allowing versatile integration into different anode structures and compatibility with a wide range of binders, facilitating scalable and cost-effective manufacturing. A key advantage of Solidion’s technology is its avoidance of chemical vapor deposition (CVD), a conventional manufacturing step that uses explosive gases like silane, posing safety risks and increasing costs. Instead, Solidion employs a silane-free process, using encapsulated silicon and metallurgical-grade or reclaimed silicon feedstock to reduce expenses. Their patented anodes can contain 45-95% silicon by weight, significantly boosting battery performance and range.

China is reportedly testing large unmanned underwater drones, known as Extra-Extra-Large Uncrewed Underwater Vehicles (XXLUUVs), which are comparable in size to conventional diesel submarines but fully autonomous. These drones, over 131 feet (40 meters) long and likely powered by hybrid diesel-electric propulsion with large lithium-based battery banks, can carry more fuel, sensors, and weapons due to the absence of human crews. With an estimated range of around 10,000 nautical miles (18,520 km), they could traverse vast ocean distances, loiter for extended periods, and potentially conduct long-range missions such as blockading strategic sea routes like the Panama Canal or the U.S. West Coast. Intended to be armed with conventional submarine weapons like mines and torpedoes, these drones might also serve as motherships for smaller drones, although this capability is considered less certain. Their long endurance and stealth make them valuable for missions including mine-laying, undersea infrastructure attacks (

Researchers at Skoltech in Russia have developed an improved cathode material for lithium-ion batteries by doping it with a small amount (0.5 mole percent) of tantalum oxide (Ta₂O₅). This modification significantly reduces the rate of battery capacity decay per cycle by nearly 50%, thereby enhancing battery lifespan. The breakthrough addresses a key challenge in nickel-rich layered oxide cathodes, which store more energy but degrade faster due to crack formation during repeated charging and discharging.

They developed a mathematical model accounting for particle shape and size to optimize this gradient and synthesized three types of gradient structures validated by experiments. To maintain this gradient during high-temperature lithium doping, the addition of tantalum oxide was crucial. Tantalum segregates to the surface of crystallites, forming a thin tantalum-rich layer that prevents transition metal interdiffusion and

Researchers at Concordia University have discovered that indigo dye, historically used for coloring denim, can significantly improve solid-state lithium-ion batteries. Unlike traditional liquid electrolytes, solid-state batteries use solid materials for lithium-ion movement, enhancing safety and energy capacity. The study found that indigo not only stores and releases lithium ions but also activates the solid electrolyte, creating a synergistic effect that boosts the battery’s overall capacity beyond what either component could achieve alone. Additionally, these batteries maintain stable performance even at temperatures as low as minus ten degrees Celsius, addressing a common limitation of organic-material-based batteries. This breakthrough is notable because organic materials typically struggle with instability when integrated into solid-state batteries due to excessive interactions with solid components. However, the controlled reaction between indigo and the electrolyte in this research enables steady and predictable battery chemistry, which is crucial for developing greener, more sustainable energy storage solutions. The use of natural molecules like indigo could simplify supply chains, reduce costs, and support the transition to more accessible

The article outlines seven practical strategies to improve electric vehicle (EV) range and battery health during winter, emphasizing the significant impact cold weather has on lithium-ion batteries. Lower temperatures slow battery chemical reactions, reducing capacity and efficiency, while winter driving demands more energy for heating and lighting, exacerbating range anxiety. Key recommendations include parking the EV in a garage and preconditioning the battery and cabin while plugged in to draw power from the grid, thus starting trips with optimal temperatures and a full charge. Using heated seats and steering wheels instead of the main cabin heater conserves energy, allowing for a cooler cabin temperature without sacrificing comfort. Additional tips focus on maintaining proper tire pressure to reduce rolling resistance and improve efficiency, using Eco Mode combined with smooth driving to limit power output and enhance safety on slippery roads, and carefully planning winter routes and charging stops. Planning involves using route tools that account for traffic, temperature, elevation, and road conditions, as well as activating battery preconditioning before fast charging to optimize charging speed.

The article discusses the strategic role Japan’s submarine fleet could play in countering China’s numerically superior navy in a potential conflict over Taiwan. While China’s People’s Liberation Army Navy (PLAN) is currently the world’s largest by number, with around 370 ships and an expected increase to 395 by 2025 and 435 by 2030, Japan’s submarine fleet is much smaller, comprising 24 conventionally powered submarines. Despite this, Japan’s submarines are technologically advanced, featuring Air-independent propulsion (AIP) systems that allow extended submerged operations and enhanced stealth, as well as lithium-ion batteries in newer classes like the Taigei-class, which improve underwater endurance and power. These subs are equipped with advanced sonar, torpedoes, and anti-ship missiles, making them formidable assets despite their smaller numbers. Geography further amplifies Japan’s strategic advantage.

Researchers at the Max Planck Institute for Polymer Research (MPI-P) in Germany, collaborating with Japanese universities, have identified and precisely measured a nanoscale space-charge layer inside operating lithium solid-state batteries that impairs their performance. This layer, less than 50 nanometers thick and located primarily at the positive electrode interface, acts as a barrier by accumulating electric charge that repels migrating ions, thereby increasing internal resistance. Despite its minuscule size—comparable to the surface thickness of a soap bubble—this charge layer contributes about 7% of the battery’s total resistance, potentially more depending on the materials used. The team employed novel combinations of Kelvin probe force microscopy (KPFM) and nuclear reaction analysis (NRA) to observe the space-charge region in real time and measure lithium accumulation, overcoming previous challenges where estimates of the layer’s thickness varied widely and were not captured under operating conditions. This breakthrough provides a clearer understanding of the internal limitations of solid-state batteries, which are otherwise promising

Researchers at Ulsan National Institute of Science and Technology (UNIST) have developed a novel method to enhance the lifespan and safety of solid-state batteries by physically stretching a fluorinated polymer electrolyte (PVDF-TrFE-CFE). This uniaxial stretching aligns the polymer chains, creating continuous pathways that significantly improve lithium-ion transport. As a result, batteries using the stretched electrolyte retained about 78% of their capacity after 200 charge-discharge cycles, compared to only 55% retention with unstretched electrolytes. The lithium-ion diffusion rate increased nearly fivefold, and ionic conductivity improved by 72%. Additionally, incorporating ceramic powder (LLZTO) into the polymer matrix enhanced mechanical flexibility, flame retardancy, and ion conductivity. Safety tests demonstrated that the new electrolyte is highly flame-retardant, extinguishing flames within four seconds, addressing a major safety concern in electric vehicle batteries that use flammable organic liquid electrolytes.

Their method involves leaching metals from dismantled batteries into an organic solvent, then selectively capturing lithium ions using a polymer-coated electrode within an electrochemical cell. The key innovation is a redox-active crown ether copolymer that selectively binds lithium even in the presence of competing metals like iron, nickel, and cobalt. This polymer can be electrochemically regenerated by applying a voltage, releasing the captured lithium for collection while leaving other metals behind, enabling repeated, efficient recovery cycles without the need for harsh chemical treatments. The study, published in ACS Energy Letters, highlights that this approach is both highly selective and energy-efficient, with lithium uptake doubled due to the redox-active polymer design. A techno-economic analysis suggests the recovered lithium could be produced at costs competitive with or lower than current market prices (

Redwood Materials, a Nevada-based battery recycler and cathode producer founded in 2017 by former Tesla CTO JB Straubel, has reportedly cut about 5% of its workforce—roughly a few dozen employees out of 1,200—shortly after raising $350 million in a Series E funding round. The company specializes in recycling materials such as cobalt, nickel, and lithium from battery scrap and used EV batteries, which it then sells back to customers including Panasonic. Redwood has also expanded into cathode production and recently launched a business repurposing old EV batteries for energy storage, a sector benefiting from the rise of AI data centers. The October funding round increased Redwood’s valuation to approximately $6 billion. Despite the recent capital infusion, the company opted for workforce reductions, though a spokesperson declined to comment on the layoffs. As of June, Redwood had accumulated over 1 gigawatt-hour of batteries for its energy storage initiatives, signaling ongoing investment in this growing market segment.

Researchers from Chang’an University and Queensland University of Technology have conducted a comprehensive review on improving lithium-ion battery (LIB) performance in extreme cold environments by developing low-temperature (LT) electrolytes. Their work, published in Springer Nature, outlines innovative strategies including lithium salt molecular design, solvent matrix optimization, interfacial engineering additives, and gel-polymer composite electrolytes to maintain battery function at subzero temperatures. The study covers various electrolyte types—ester-based, ether-based, nitrile-based, and gel-polymer systems—highlighting how properties like freezing point and dielectric constant influence lithium-ion solvation and battery performance. Notably, machine learning models trained on over 150,000 molecular candidates have accelerated electrolyte discovery by accurately predicting key properties such as melting point and viscosity. The team emphasizes the role of machine learning-guided formulation strategies that enable high-throughput virtual screening and structure–property relationship predictions, facilitating rapid development of LT electrolytes.

Scientists at the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Germany have developed a new class of fiber-based silicon anodes for lithium-ion batteries that could increase energy density by up to 250%. Unlike conventional graphite anodes, which store about 370 mAh per gram, silicon theoretically offers over 4,200 mAh per gram, promising significantly higher capacity at comparable cost. However, silicon’s tendency to expand up to 300% during lithium absorption has caused cracking and rapid battery failure in past attempts. The new approach uses flexible, electrically conductive nonwoven fiber substrates to accommodate silicon’s volume changes, preventing damage during charging cycles. The FACILE project, involving regional partners, aims to produce silicon anodes with a practical capacity of at least 1,000 mAh per gram, translating to a substantial boost in battery energy density. The team has begun integrating these anodes into small test cells and plans to refine and scale production for larger cells suitable for electric vehicles (

Rice University researchers have developed a novel two-step flash Joule heating chlorination and oxidation (FJH ClO) process for recycling lithium-ion batteries that significantly reduces chemical use and energy consumption. This acid-free method rapidly extracts lithium, cobalt, and graphite from spent batteries with high purity by first exposing battery waste to chlorine gas to break down materials, then heating in air to form metal oxides that separate from lithium chloride, which dissolves easily in water. Compared to conventional recycling methods that rely on strong acids, long reaction times, and generate wastewater, the FJH ClO process uses about half the energy and up to 95% fewer chemicals, offering a cleaner, faster, and more environmentally friendly alternative. The technique enables full-spectrum recovery of critical battery materials in a streamlined, single-route process, avoiding multiple chemical treatments common in existing methods. This efficiency not only promises economic benefits through lower operating costs and faster turnaround but also helps reduce reliance on new mining, mitigating environmental impact. The research

Researchers at the Ulsan National Institute of Science and Technology (UNIST) have developed a novel gel polymer electrolyte (GPE), named An-PVA-CN, that could significantly enhance electric vehicle (EV) battery performance by increasing driving range by 2.8 times and extending battery life nearly threefold. Traditional lithium-ion batteries face challenges at high voltages (above ~4.4 V), where nickel-rich cathodes release surface oxygen that forms reactive oxygen species (ROS). These ROS degrade the electrolyte, damage cathode structure, cause nickel dissolution, and generate gas that swells batteries, increasing failure risk and shortening lifespan. The new gel electrolyte addresses these issues with a dual protection mechanism: anthracene molecules bind to unstable surface oxygen to prevent ROS formation and also scavenge any ROS already present, neutralizing them before damage occurs. Additionally, nitrile groups in the polymer bind to nickel ions, preventing their dissolution and maintaining cathode structural integrity. This results in reduced cracking, degradation

Swiss researchers, led by the Bern University of Applied Sciences (BFH) under the CircuBAT project, have developed a pioneering robotic system to enhance the sustainable second life and recycling of electric vehicle (EV) lithium-ion batteries. This innovation aims to close the loop between battery production, use, and recycling by automating the dismantling, sorting, and upcycling processes, which have traditionally been labor-intensive and hazardous. The system, designed at the Swiss Battery Technology Center (SBTC), uses precision robotics to safely separate battery modules and recover high-quality raw materials with minimal manual handling, thereby improving recycling efficiency and reducing environmental impact. In addition to recycling, the project introduced a “Battery Expert System” that analyzes aging patterns of thousands of cells to identify those suitable for repair or repurposing, enabling retired EV batteries to be reused as stationary energy storage systems for buildings or renewable energy grids. The researchers also developed automated dismantling methods, direct material recovery techniques, and novel electrode coatings that lower energy consumption

Researchers at South Korea’s Ulsan National Institute of Science and Technology (UNIST) have developed an innovative, eco-friendly recycling process that recovers over 95% of nickel and cobalt from used electric vehicle (EV) batteries with near-perfect purity. Unlike conventional wet recycling methods that rely on strong acids and multi-step chemical treatments, this new technique uses a selective electrochemical separation facilitated by a deep eutectic solvent (DES) called ethaline, composed of ethylene glycol and chloride ions. This solvent selectively binds nickel and cobalt ions, enabling their efficient separation through distinct reduction voltages, thereby overcoming the typical trade-off between purity and recovery rate. The process achieves a nickel-cobalt separation factor greater than 3,000 and recovers more than 97% nickel from synthetic mixtures, with real battery leachates yielding 99.1% nickel purity and 98.8% cobalt purity at recovery rates above 95%. Additionally, the method’s electrodeposition step naturally generates chlorine within

The Philippines holds a significant geological advantage in the global electric vehicle (EV) revolution as one of the world’s largest nickel producers, accounting for about 25% of global supply with 430,000 metric tons produced in 2024. However, the country currently exports 90% of its nickel as raw ore, missing out on the higher-value midstream and downstream processing stages that convert nickel into battery-grade materials essential for EV batteries. Nickel is a critical component in lithium-ion batteries, particularly in Nickel Manganese Cobalt Oxide (NMC) cells, which offer high energy density and driving range. The Philippines also produces around 3% of global cobalt, further positioning it to develop NMC-based battery production despite a market trend toward Lithium Iron Phosphate (LFP) cells for cost reasons. To capitalize on its nickel resources, experts suggest the Philippines enforce raw ore export bans by 2025 and invest in hydrometallurgical processing technologies like High Pressure Acid Leaching (

US-based Sakuu has demonstrated a significant breakthrough in electric vehicle (EV) battery technology with its Kavian platform, which uses a fully dry-processed cathode to produce battery electrodes exhibiting exceptional cycle life. A test cell made via Kavian’s dry-printing process retained 83% of its charge after 4,000 cycles, effectively doubling the typical EV battery standard of 2,000 cycles at 80% state of health. This milestone challenges prevailing skepticism about dry manufacturing methods for lithium-ion battery electrodes, particularly cathodes, and suggests that dry processing can match or exceed the performance of conventional wet-coated batteries. The Kavian platform’s dry process addresses key limitations of traditional wet-coated battery manufacturing by eliminating toxic solvents and water, reducing CO2 emissions by 55%, shrinking the manufacturing footprint by 60%, and cutting utility operating costs by 30%.

British engineer and YouTuber Chris Doel created a 2.52 kWh off-grid power wall using 500 recycled lithium-ion batteries salvaged from disposable vape pens. By collecting discarded vapes, testing each battery for viability, and assembling them into 56 modules with 3D-printed holders, Doel constructed a system that delivers about 50 volts DC. This power wall, connected to an inverter, converts the energy to standard 230 volts AC, enabling him to run his workshop appliances such as a kettle, microwave, fan, and computer without relying on the electrical grid. Doel’s project not only showcases a practical reuse of electronic waste but also highlights the environmental impact of disposable vapes, which often end up in landfills despite containing rechargeable batteries. His setup, weighing around 38 kilograms and valued at approximately £2,500 if built with new batteries, was assembled using mostly reclaimed materials and repurposed components like a scooter battery management system.

Researchers at Huazhong University of Science and Technology have developed a novel molten salt-based method to restore degraded lithium-ion battery cathodes, specifically targeting NCM811 (LiNi₀.₈Co₀.₁Mn₀.₁O₂), a common material in electric vehicle (EV) batteries. Unlike traditional recycling techniques that extract metals but destroy the cathode’s atomic structure, this approach uses a ternary molten salt mixture (lithium hydroxide, lithium nitrate, and lithium salicylate) to repair defects and replenish lost lithium ions. The process restores the cathode’s original crystal structure and performance, achieving an initial discharge capacity of 196 mAh/g and retaining 76% capacity after 200 cycles, outperforming most current recycling methods. The molten salt method operates at lower temperatures without harsh chemicals, reducing energy consumption and environmental impact. This technique effectively heals both internal and surface damage, removing unwanted layers and reviving the ordered layered structure critical for

A Stanford-led research team has achieved a breakthrough by pushing iron into an unprecedented high-energy state, enabling it to release and reabsorb up to five electrons—significantly more than the usual two or three. This was accomplished by engineering a nanoscale lithium–iron–antimony–oxygen compound with particles just 300 to 400 nanometers in diameter, which maintained structural stability during repeated charging cycles. The discovery was confirmed through advanced X-ray spectral modeling, revealing that both iron and oxygen atoms cooperatively contribute to this enhanced electron exchange. This advancement could revolutionize lithium-ion battery technology by providing a high-voltage, iron-based cathode that is more powerful and substantially cheaper than current cobalt- or nickel-based alternatives. Iron, previously considered unsuitable for high-voltage applications, now emerges as a sustainable and cost-effective material, potentially reducing reliance on expensive and environmentally problematic metals like cobalt. The research, building on theoretical work from 2018, was published in Nature Materials and may also impact other

The article from CleanTechnica argues that despite the Trump administration's efforts to roll back clean energy policies in 2025, the broader transition to clean energy in the United States and globally remains unstoppable. While Trump has sought to dismantle federal incentives, withdraw from the Paris Agreement, and revive fossil fuel industries, the fundamental drivers of the energy transition—innovation, economies of scale, and technological learning—continue to push costs down and deployment forward. Solar, wind, and lithium-ion battery technologies have become increasingly affordable and efficient, making clean energy investments financially attractive regardless of political shifts. A key example of this momentum is the rapid expansion of battery manufacturing in the U.S., particularly across the Midwest and Southeast, where over 800 GWh of battery cell capacity projects have been announced or are under construction. These large-scale, multibillion-dollar projects are bound by long-term contracts and local incentives, making them resilient to policy reversals. Although Trump’s policies have slowed deployment by cutting subsidies and canceling

Researchers at the University of Wisconsin-Milwaukee, led by Professor Deyang Qu, have developed a novel method to recycle used lithium iron phosphate (LFP) electric vehicle (EV) batteries into fertilizers. This process employs an ion-exchange technique to recover lithium by replacing it with potassium, leaving behind key fertilizer components such as phosphorus, potassium, and nitrogen. The innovation addresses the growing challenge of EV battery waste, particularly as conventional recycling is costly and yields limited value beyond lithium recovery. By converting battery materials into fertilizers, the method not only reduces environmental waste but also supports agriculture, offering a potentially sustainable economic solution. The research, supported by UWM and the USDA Agricultural Research Service, aims to scale up fertilizer production for field testing, including planned trials on tomato crops. This approach could create a domestic supply of essential fertilizer minerals, currently mostly imported, while reducing the energy footprint associated with mining and transportation. The method is particularly relevant given the expected surge in expired lithium-ion batteries after about a decade

Researchers at the University of Waterloo have developed a novel gravity-based energy storage system designed for high-rise buildings to store renewable energy efficiently. This system integrates photovoltaic (PV) facades on multiple building sides, small rooftop wind turbines, lithium-ion batteries, and a rope-hoist gravity storage mechanism. Excess electricity generated by the PV panels and wind turbines is used to lift a heavy mass—typically steel or concrete blocks—within a vertical shaft, storing energy as gravitational potential. When energy demand rises or renewable production falls, the mass is lowered to drive a generator, converting the stored potential energy back into electricity. The lithium-ion batteries serve primarily for rapid response during sudden surpluses or shortages. The researchers employed a multi-objective optimization framework to minimize both the levelized cost of electricity (LCOE) and grid dependency (GD) across 625 parametric building designs varying in energy use intensity (EUI) and geometric configurations.

A research team in Korea has developed a novel hybrid anode material for electric vehicle (EV) batteries that significantly enhances fast-charging capability while extending battery lifespan. This hybrid anode combines conventional graphite particles (mesocarbon microbeads, MCMB) with curved nanosheets of chlorinated contorted hexabenzocoronene (Cl-cHBC), creating larger interlayer spaces and nanoscale channels that facilitate efficient lithium-ion transport. The sequential lithium-ion insertion—first into the nanosheets, then into graphite—prevents the formation of "dead lithium," a common cause of capacity loss during rapid charging. Experimental results demonstrated that batteries with this anode deliver over four times the capacity of standard graphite under high-rate charging and maintain 70% capacity after 1,000 cycles in full-cell tests. Pouch cells showed stability for over 2,100 cycles with 99% Coulombic efficiency, indicating strong durability for practical use.

Researchers have developed an innovative battery recycling method that harnesses a spent lithium-ion battery’s own stored chemical energy to recover key metals with high efficiency. By recharging the battery to a controlled level (around 70% capacity), they trigger a self-heating thermal runaway reaction that raises the internal temperature to about 1,100°C. This heat breaks down complex cathode materials, such as nickel manganese cobalt oxide (NMC), into simpler metallic or oxide forms, facilitating easier extraction without the need for extensive external energy or harsh chemicals. The process involves a two-stage material recovery: first, washing the thermally treated powder with water to remove soluble lithium salts (recovering over 60% lithium), and second, using dilute hydrochloric acid to dissolve remaining lithium and transition metals, achieving over 93% lithium and 95% transition metal recovery in tested cells. This method contrasts with conventional recycling techniques like pyrometallurgy and hydrometallurgy, which require high energy input or large

Researchers at Japan’s Tohoku University have demonstrated that two pressure-assisted sintering methods—hot pressing (HP) and spark plasma sintering (SPS)—are equally effective for fabricating dense, high-quality garnet-type oxide solid electrolytes (Li₇La₃Zr₂O₁₂ or LLZO) for next-generation solid-state lithium metal batteries (SSLMBs). Both techniques achieve nearly full densification (~98%) in under five minutes without significant differences in ionic conductivity or microstructure. This challenges the previously held belief that SPS offers unique advantages due to a “plasma effect,” showing instead that densification is driven primarily by applied pressure and heat. The study, published in Small, highlights that either HP or SPS can be chosen based on factors such as cost, equipment availability, and scalability rather than presumed performance superiority. This finding is significant because conventional oxide electrolyte fabrication requires prolonged high-temperature sintering, which is costly and leads to lithium evaporation.

MIT researchers have developed a new model called the Coupled Ion-Electron Transfer (CIET) model that redefines the fundamental chemical reaction of lithium-ion intercalation in batteries. This reaction governs how lithium ions insert into solid electrodes, directly affecting battery charging and discharging speeds. Previous models, notably the Butler-Volmer equation, assumed ion diffusion was the rate-limiting step, but experimental data often conflicted with these predictions. Using a novel electrochemical technique involving repeated short voltage bursts, the MIT team precisely measured intercalation rates across over 50 electrolyte-electrode combinations, including common battery materials like lithium nickel manganese cobalt oxide and lithium cobalt oxide. The study found that lithium intercalation rates are significantly slower than previously thought and are controlled by the simultaneous transfer of both lithium ions and electrons to the electrode—a process described by the CIET model. This coupled transfer lowers the energy barrier for the reaction and is the true speed-limiting step in battery operation. The insights from this

Researchers at MIT have developed a novel method to decode faint acoustic signals emitted by lithium-ion batteries during charge and discharge cycles, linking specific sound patterns to internal degradation processes such as gas generation and electrode material fracturing. By combining electrochemical testing with sensitive acoustic recordings under real-world conditions, the team was able to noninvasively monitor battery health, identifying distinct acoustic signatures even amid noisy data. This approach was validated through electron microscopy, confirming the correlation between sounds and internal battery damage. Unlike previous methods that relied on simple sound thresholds, the MIT researchers employed advanced wavelet transforms to isolate meaningful signals from background noise, similar to techniques used in structural health monitoring of bridges. This acoustic monitoring provides an additional diagnostic tool beyond traditional voltage and current measurements, offering insights into battery lifespan and safety risks, including early warnings of thermal runaway. The technology has immediate applications in material research, manufacturing quality control, and electric vehicle monitoring, with ongoing collaborations such as one with Tata Motors to implement real-world diagnostic systems.

Dutch battery startup LeydenJar is developing silicon anode technology that could significantly challenge China's dominance in lithium-ion battery production, particularly in graphite anodes. With recent funding led by investors Exantia and Invest-NL, plus a €10 million commitment from a U.S. customer, LeydenJar plans to open its first manufacturing facility, PlantOne, in Eindhoven by 2027. Their silicon anodes promise a 50% increase in energy density over traditional graphite anodes, a substantial improvement compared to the incremental gains seen so far in the industry. LeydenJar’s innovation lies in using plasma vapor deposition to grow spongy silicon columns on copper sheets, allowing the silicon to expand and contract without crumbling—a common challenge due to silicon’s tendency to swell during lithium ion storage. This structure supports faster charging and a lower carbon footprint. While the anodes can endure over 450 charge cycles before losing 80% capacity, this still falls short of the 1,000 cycles automakers

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have developed a novel impact-resistant additive to enhance the safety of lithium-ion batteries used in electric vehicles (EVs). Inspired by the shear-thickening behavior of oobleck—a cornstarch and water mixture that solidifies under pressure—Gabriel Veith and his team created an additive composed of uniformly sized superfine silica particles suspended in the battery electrolyte. This additive instantly hardens upon impact, preventing the battery’s electrodes from touching and short-circuiting, which can otherwise cause fires. The uniform particle size is critical to ensure even dispersion and effective solidification, and the additive can be incorporated into existing battery manufacturing processes with minimal modifications. The technology, branded as Safe Impact Resistant Electrolytes (SAFIRE), was licensed in 2022 to Safire Technology Group, a startup advancing its commercialization for automotive, defense, and electric vertical take-off and landing (eVTOL) aircraft applications.

Researchers from Hebei University and Longyan University in China have developed a novel dual-shell coating, termed LiF@spinel, that significantly enhances the durability and performance of lithium-rich cathodes in lithium-ion batteries. This design integrates two protective layers: a spinel buffer that facilitates rapid lithium-ion transport and an outer lithium fluoride (LiF) layer that chemically bonds with nickel-fluoride anchors to shield the cathode from corrosive electrolyte attacks. Constructed via in situ reconstruction, the coating forms a seamless 3D network confirmed by advanced microscopy and spectroscopy techniques. Performance tests demonstrated that batteries with this coating retained 81.5% capacity after 150 cycles at 2 C, outperforming uncoated counterparts, and maintained over 80% capacity even under ultrafast cycling at 5 C, with reduced resistance and fewer degradation by-products. This breakthrough addresses key challenges in lithium-ion battery technology, such as cathode instability, electrolyte breakdown, capacity fade, and safety risks, which

Researchers at the University of Wisconsin–Madison have developed a novel, low-cost electrochemical method to efficiently recycle lithium from spent lithium-iron-phosphate (LFP) electric vehicle (EV) batteries. Unlike conventional recycling methods that are economically unviable for LFP batteries due to the absence of valuable metals other than lithium, this new two-step process selectively extracts lithium ions using a lithium-ion storage electrode and then recovers them as high-purity lithium chemicals such as Li3PO4, Li2CO3, or LiOH. The method regenerates the acid used in lithium leaching, minimizing chemical consumption and waste, thus offering a sustainable and environmentally friendly recycling approach. The researchers demonstrated the process’s effectiveness using both commercial LFP batteries and industrial black mass derived from spent batteries. This electrochemical system operates under mild conditions without requiring special inputs, making it potentially scalable and cost-effective. Given the growing market shift toward LFP batteries—which are cheaper and safer but less valuable to recycle due to

MIT researchers have developed a novel “self-assembling” electrolyte material for electric vehicle (EV) batteries that significantly simplifies recycling. Inspired by a Harry Potter scene where Dumbledore cleans a room with a flick of his wrist, the team designed a battery electrolyte that can quickly disassemble when exposed to a simple organic solvent. This allows the battery’s layers to separate naturally, enabling easier sorting and recycling of individual components. Unlike conventional batteries, which are difficult and costly to recycle due to complex and harsh chemical processes, this new approach embraces a “recycle-first” design philosophy, creating materials that prioritize recyclability from the outset. The electrolyte material is composed of aramid amphiphiles (AAs), molecules that self-assemble into durable nanoribbons mimicking the strong chemical structure of Kevlar, combined with polyethylene glycol (PEG) to conduct lithium ions. These nanoribbons form a solid-state electrolyte that is both tough and functional, facilitating lithium-ion transport between the battery’s cathode and

The article from CleanTechnica discusses the transformative impact of combining solar power with battery storage on energy systems and societies. It highlights a reader’s insightful prediction that as battery packs become cheaper and more widespread, affluent consumers will increasingly disconnect from traditional power grids, opting for self-sufficient solar-plus-storage setups. This shift could reduce utility profits and halt grid improvements, potentially leading to government intervention or a decline in grid services. However, this decentralization also increases system redundancy, reducing the risk of widespread outages caused by cyberattacks, natural disasters, or other disruptions, signaling a move from centralized grids to localized “islanding” energy systems. A real-world example is Pakistan, where cheap Chinese solar panels and lithium-ion batteries have enabled many users to exit the unreliable and costly traditional grid.

Scientists at the MEET Battery Research Center and the University of Münster have developed an innovative recycling method for dry-processed lithium-ion battery cathodes, advancing sustainable and circular battery production. Unlike traditional wet processing, which uses solvent-based slurries, dry processing employs polytetrafluoroethylene (PTFE) as a binder, eliminating costly and toxic solvents. The new recycling technique leverages mild mechanical milling to delaminate and recover cathode materials from aluminum current collectors without harsh chemicals or high heat, preserving the integrity of active materials and the PTFE binder network for direct reuse in battery manufacturing. This approach not only supports greener battery production but also proves economically viable. Tests demonstrated that electrodes made from recycled materials perform comparably to those from new composites. A life-cycle cost assessment indicated that even at a low scrap rate of 5%, the method reduces electrode processing costs by about 2.6% (approximately USD 0.8 per kWh) and lowers carbon emissions by around 2

A recent Australian study highlights that discarded electric vehicle (EV) lithium-ion batteries still retain about 80% of their lithium content, presenting a significant opportunity for recycling. Recycling these batteries not only recovers high-purity lithium (near 99%) but also valuable metals like nickel and cobalt. Compared to traditional lithium mining, recycling reduces carbon emissions by 61%, energy use by 83%, and water consumption by 79%, making it a cleaner and more sustainable approach. With the global lithium-ion battery market expected to grow 13% annually and battery waste projected to reach 137,000 tons per year in Australia alone, recycling could address both environmental and economic challenges, including job creation and waste reduction. Despite these benefits, challenges remain, such as rapidly evolving battery chemistries and lagging policy development, which complicate recycling processes.

Researchers at Rice University have discovered that the internal chemistry of battery materials, rather than just their physical structure, is crucial to improving the durability and capacity of lithium-ion batteries. Using high-resolution X-ray imaging, the team observed in real-time how energy reactions within thick battery electrodes often create uneven “hot spots” near the surface, leaving deeper regions inactive. This uneven reaction causes internal cracking, faster degradation, and reduced energy capacity, which limits the performance and lifespan of batteries, particularly those designed to hold more energy. The study, led by materials scientist Ming Tang, compared two common battery materials: lithium iron phosphate (LFP) and a nickel manganese cobalt oxide blend (NMC). Contrary to prior assumptions that pore structure dictated performance, the researchers found that the thermodynamic properties of the materials primarily determine how evenly reactions spread. NMC electrodes exhibited more balanced and stable reactions, while LFP showed pronounced hot spots near the separator surface. To aid battery design, the team introduced a new metric called the “

Researchers at the US National Renewable Energy Laboratory (NREL) are employing ultra-high-resolution nano-computed tomography (nano-CT) scans to analyze and revive spent lithium-ion batteries from electric vehicles (EVs). This nondestructive imaging technique, capable of resolving features down to 50 nanometers, reveals microscopic cracks and internal defects in battery cathodes that traditional methods miss. These cracks, particularly in nickel-rich cathode particles, impede lithium-ion flow and degrade fast-charging capabilities despite retained energy capacity. By correlating structural damage with performance loss, the team can identify specific degradation patterns and tailor direct-recycling methods that refurbish rather than fully rebuild cathodes. The direct-recycling approach aims to repair damaged cathodes through gentler mechanical treatments that restore cracked particles or replace only damaged sections, preserving the crystal structure critical for high energy density. This method contrasts with conventional recycling, which dissolves electrodes into basic chemicals—an energy-intensive process that also risks losing valuable metals. Successful implementation would reduce processing

The article discusses advances in understanding and improving lithium-ion battery recycling through high-resolution nano-CT imaging, led by researchers at the National Renewable Energy Laboratory (NREL). Lithium-ion batteries rely on scarce and valuable minerals such as lithium, nickel, cobalt, manganese, and graphite, with much of the global supply chain controlled by China. To reduce dependence on foreign markets and extend the lifespan of critical materials, direct recycling of battery cathodes within the United States is being explored as a more efficient and cost-effective alternative to traditional recycling methods, which are energy-intensive and break materials down to their elemental forms. NREL’s nano-CT scanner, capable of 50-nanometer spatial resolution, allows nondestructive, real-time visualization of internal battery structures, revealing microscopic degradation that impacts battery performance. Researchers found that although end-of-life battery materials retained similar energy capacity to new cells, their charging rates were significantly reduced due to morphological damage—specifically, particle cracking within the cathode microstructure.

The article critiques the Trump administration’s 2025 plan to reduce government R&D investment, contrasting it with insights from Mariana Mazzucato’s 2024 book, which highlights the essential role of state-led innovation in driving transformative technologies. Mazzucato challenges the common belief that breakthrough innovation is primarily driven by private firms, emphasizing that governments have historically borne the significant risks of early-stage, radical research. She provides examples such as the internet, biotechnology, and pharmaceuticals, where foundational technologies were developed and funded by public agencies long before private companies commercialized them. Venture capital, often celebrated as a key innovation driver, typically enters later in the cycle, focusing on scaling rather than pioneering uncertain technologies. The article further illustrates how critical energy technologies like solar panels, wind turbines, and lithium-ion batteries emerged from decades of patient government R&D, underpinning companies like Tesla. Even the shale gas boom, commonly viewed as a free-market success, relied heavily on federal funding for early hydraulic fracturing research.

The National Renewable Energy Laboratory (NREL) has developed an innovative physics-informed neural network (PINN) model that significantly enhances the efficiency and accuracy of diagnosing lithium-ion battery health. Traditional battery diagnostic models, such as the Single-Particle Model (SPM) and the Pseudo-2D Model (P2D), provide detailed insights into battery degradation mechanisms but are computationally intensive and slow, limiting their practical use for real-time diagnostics. NREL’s PINN surrogate model integrates artificial intelligence with physics-based modeling to analyze complex battery data, enabling battery health predictions nearly 1,000 times faster than conventional methods. This breakthrough allows researchers and manufacturers to non-destructively monitor internal battery states, such as electrode and lithium-ion inventory changes, under various operating conditions. By training the PINN surrogate on data generated from established physics models, NREL has created a scalable tool that can quickly estimate battery aging and lifetime performance across different scenarios. This advancement promises to improve battery management, optimize design, and extend the operational lifespan of energy storage systems, which are critical for resilient and sustainable energy infrastructures.

During protests in downtown Los Angeles sparked by aggressive immigration raids conducted by ICE under the Trump administration, several Waymo autonomous vehicles and Lime e-scooters were vandalized and set on fire. On Sunday evening, protesters attacked five Waymo robotaxis by slashing tires, breaking windows, spray-painting anti-ICE slogans, and igniting the cars. Some Lime e-scooters were also thrown into the burning vehicles. The LAPD warned that burning lithium-ion batteries from these devices release toxic gases, posing health risks to bystanders. The exact motive behind targeting Waymo vehicles remains unclear, though previous police investigations have utilized footage from Waymo’s cars. Waymo stated it is cooperating with the LAPD and intends to pursue criminal charges and seek damages for the vandalism. There are unconfirmed reports that Waymo may have removed its vehicles from Los Angeles following the attacks. The protests began on June 6 in response to ICE raids that resulted in over 100 immigrant arrests, escalating into both peaceful and violent demonstrations across multiple cities, including freeway blockades. In response, President Trump federalized the California National Guard and deployed troops to LA, a move opposed by state officials including Governor Gavin Newsom, who called it a breach of state sovereignty. Defense Secretary Pete Hegseth indicated readiness to deploy Marines if violence persists. Videos have surfaced showing LAPD using force against protesters and journalists during the unrest.
