When Lightning Strikes Twice: The Ducati V21L's (Almost) Final Thunder - CleanTechnica
The article highlights Ducati’s groundbreaking V21L electric motorcycle, which has significantly advanced the performance standards of electric racing in the 2025 FIM MotoE World Championship. Weighing just over 216 kilograms after battery improvements, the V21L has consistently broken records and posted lap times competitive with traditional Moto3 combustion-engine bikes. Ducati’s engineering innovations, including higher energy density battery cells, corner-specific traction control, and chassis refinements like an extended wheelbase and adjustable swingarm pivot, have collectively transformed the bike’s handling and speed, effectively closing the gap between electric and combustion racing machines. The 2025 season reached a dramatic climax at the Misano round, where intense competition among riders like Alessandro Zaccone, Mattia Casadei, and Lorenzo Baldassarri kept the championship undecided until the final race in Portugal. Despite the V21L’s dominance and the thrilling racing it enabled, the MotoE series is facing an “indefinite hiatus,” casting uncertainty on the future

Panasonic, a major battery supplier for Tesla, is developing a new “anode-free” electric vehicle (EV) battery technology that could increase battery capacity by 25%, potentially adding about 90 miles (145 km) of range to the Tesla Model Y without enlarging the battery pack. This technology eliminates the anode during manufacturing, allowing a lithium metal anode to form upon first charge, which frees up internal space for a higher concentration of active cathode materials such as nickel, cobalt, and aluminum. Besides boosting energy density and driving range, the approach also offers the possibility of producing lighter and cheaper batteries by reducing battery size while maintaining current range, and by lowering the proportion of costly nickel. The announcement comes amid Tesla’s recent market share decline in the U.S. due to increased competition. While Panasonic has not disclosed specific impacts on manufacturing costs or consumer prices, this advancement could provide Tesla a competitive edge in the crowded EV market. Panasonic is not alone in pursuing anode-free battery designs

Solid-state batteries hold significant promise for electric vehicles (EVs) by offering higher energy density, faster charging, and improved safety compared to traditional lithium-ion batteries. Lithium-ion technology, which currently powers most EVs and consumer electronics, is nearing its energy density limits—around 260 Wh/kg—necessitating heavier battery packs for longer ranges and requiring cooling systems to prevent thermal runaway. In contrast, solid-state batteries replace the liquid electrolyte with solid materials such as ceramics or polymers, enabling denser electrodes and potentially exceeding 400 Wh/kg energy density with lithium metal anodes. However, this architecture introduces challenges like high interfacial resistance, mechanical stress during cycling, and dendrite formation, which can cause short circuits. Unlike liquid electrolytes that self-heal electrode gaps, solid electrolytes require precise manufacturing techniques to maintain stable interfaces. The main barrier to widespread adoption of solid-state batteries is scaling up manufacturing to automotive levels. Researchers Mihri Ozkan and Cengiz Ozkan from the University of California

The National Renewable Energy Laboratory (NREL) has developed the Ultra-Low Inductance Smart (ULIS) power module, a compact silicon carbide device that delivers five times greater energy density than previous designs while being smaller and lighter. Operating at 1200 volts and 400 amps, ULIS is designed for high-intensity applications such as data centers, microreactors, next-generation aircraft, military vehicles, and power grids. Its key innovation lies in drastically reduced parasitic inductance—seven to nine times lower than current state-of-the-art modules—enabling ultrafast, ultraefficient electrical switching that maximizes usable power output and improves overall energy efficiency. ULIS features a unique flat, octagonal design that allows more semiconductor devices to be housed in a smaller footprint, enhancing compactness and weight reduction. This design also facilitates maximum magnetic flux cancellation, contributing to its low-loss, high-efficiency electrical performance. Additionally, ULIS incorporates advanced self-monitoring capabilities to predict component failures,

Chinese researchers at Tianjin University have developed a lithium metal battery with an unprecedented energy density of 600 Wh/kg, potentially doubling the energy density of Tesla’s best batteries and quadrupling that of BYD’s Blade batteries. This breakthrough could significantly extend the driving range of electric vehicles (EVs), alleviate range anxiety, reduce battery weight, and enhance performance and efficiency. Additionally, the battery’s high energy density and safety features open up promising applications in electric aircraft and drones, where extended flight times and reliability are critical. The team achieved this advancement by rethinking the traditional lithium-ion solvation structure, creating a more flexible, non-localized interaction between lithium ions and solvent molecules. Using machine learning to optimize lithium salts and solvents, and incorporating fluorine to enhance thermal stability, the battery demonstrated remarkable safety characteristics: it operates at temperatures as low as -60 °C without freezing, resists ignition under open flame, and withstands nail penetration tests. Early tests showed stable performance after 90 charge cycles and

Anhui Anwa New Energy Technology, a Chinese company partly owned by automaker Chery and battery maker Gotion High-Tech, has unveiled its first batch of solid-state battery samples with an energy density of 136 watt-hours per pound. These first-generation batteries meet the new ‘No Fire No Explosion’ safety standard and were produced at Anwa’s factory in China’s Wuhu Economic and Technological Development Zone. The company employs a fully integrated production line with a five-step dry manufacturing process that reduces energy consumption by 20% and fixed asset investment by 30%, enhancing sustainability and cost-effectiveness. Anwa plans to expand its facility with a 5 GWh solid-state battery R&D center and a fully automated production line to support large-scale manufacturing. Anwa has begun trial production of second-generation solid-state battery packs expected to reach an energy density of approximately 181 watt-hours per pound, a significant improvement over the first generation. The company aims to start mass production of third-generation batteries by

Nascent Materials, a startup founded by Chaitanya Sharma, has emerged from stealth mode with a novel manufacturing process aimed at improving lithium-ion battery cathodes, specifically lithium-ion-phosphate (LFP) and lithium-manganese-iron-phosphate (LMFP) materials. Sharma, who has experience at Tesla’s Gigafactory and iM3NY, developed a method that can enhance cathode energy density by up to 12% while reducing production costs by 30%. Unlike pursuing new battery chemistries, Nascent focuses on optimizing material processing to achieve more consistent particle size and shape, which improves packing density and overall battery performance. The process also consumes less energy and can utilize lower-purity raw materials, potentially broadening domestic supply sources. Nascent’s approach addresses significant supply chain challenges, particularly the inconsistent quality of cathode materials available to smaller manufacturers, a problem Sharma witnessed firsthand at iM3NY. By providing more reliable and locally sourced materials, Nascent aims to reduce
