Researchers at the Paul Scherrer Institute (PSI) in Switzerland have developed a novel manufacturing process that significantly enhances the durability and performance of lithium-metal all-solid-state batteries, a promising technology for safer, higher energy density, and faster-charging batteries. The team tackled two major challenges: lithium dendrite formation and unstable anode–electrolyte interfaces. They employed a gentle sintering technique at a low temperature of 176°F (80°C) to densify the sulfide-based argyrodite solid electrolyte (Li₆PS₅Cl) without compromising its chemical stability. This method produces a dense, uniform microstructure that resists dendrite penetration while maintaining fast lithium-ion transport. In addition, the researchers applied an ultra-thin (65 nm) lithium fluoride coating on the lithium metal anode via vacuum evaporation. This coating acts as both a chemical shield against electrolyte decomposition and a physical barrier to dendrite growth, significantly improving the battery’s durability and reliability. Laboratory tests showed

solid-state-batteryenergy-storageelectric-motorcyclesbattery-technologyclean-energyelectric-vehiclesenergy-innovationChina reports 824 Wh/kg solid-state EV battery, targets 1,000 Wh/kg
Chinese solid-state battery developer WeLion New Energy has announced a laboratory breakthrough achieving an energy density of 824 Wh/kg in solid-state battery tests, significantly surpassing current EV battery standards. This milestone, revealed by WeLion Chairman Yu Huigen, positions the company at the forefront of the global solid-state EV battery race, with a long-term goal to exceed 1,000 Wh/kg. Such energy density could enable electric vehicles to have much longer driving ranges or lighter battery packs compared to today’s lithium iron phosphate batteries, which typically deliver 150-180 Wh/kg. Solid-state batteries, which use solid electrolytes instead of liquid ones, promise enhanced safety, thermal stability, faster charging, and higher efficiency. Despite this technical progress, WeLion acknowledges substantial challenges remain before large-scale EV deployment is feasible, primarily due to high costs associated with sulfide-based solid electrolytes. As a result, the company plans to initially target niche markets where safety is critical and pricing is less sensitive, such as humano

Scientists at the University of Oxford have developed a novel class of organic materials called state-independent electrolytes (SIEs) that maintain high ionic conductivity even after solidifying, challenging the long-held electrochemical principle that ion movement slows drastically when a liquid electrolyte solidifies. These SIEs enable ions to move through solid structures as quickly as they do in liquid form, overcoming the "freezing out" effect that has hindered the performance of solid-state batteries compared to their liquid-based counterparts. The key innovation lies in the molecular design: disc-shaped molecules with flexible sidechains stack into rigid columns while their "soft bristles" create a permeable environment, allowing negative ions to flow freely through the solid matrix. This breakthrough offers significant advantages for battery manufacturing and safety. The electrolyte can be heated and poured as a liquid to thoroughly infiltrate battery electrodes, then cooled to form a stable solid that eliminates leakage and fire risks typical of liquid electrolytes, all without sacrificing performance. Due to their lightweight, flexible

Researchers at Georgia Tech have developed a novel solid-state battery that blends lithium with soft sodium metal, significantly reducing the high pressure typically required for solid-state battery operation. This breakthrough addresses a major limitation of solid-state batteries, which usually need heavy and bulky metal plates to maintain pressure, making them impractical for widespread use. By incorporating sodium, which is electrochemically inactive but very soft, the battery maintains better contact with the solid electrolyte under lower pressure, enhancing performance and potentially enabling lighter, longer-lasting batteries. The team drew inspiration from biology, specifically the concept of morphogenesis, to explain how the sodium-lithium combination adapts structurally during battery use. This biological analogy helped them understand the deformable nature of sodium within the battery, which adjusts to changes and improves stability. Funded partly by DARPA, the research promises significant advancements, including electric vehicles capable of traveling 500 miles on a single charge and longer-lasting phone batteries. While commercialization challenges remain, this innovation could mark a major leap forward in battery technology by making solid-state batteries more competitive with current lithium-ion standards.

Researchers from Skolkovo Institute of Science and Technology (Skoltech) and the AIRI Institute have achieved a significant breakthrough in solid-state battery technology by using machine learning to accelerate the discovery of high-performance battery materials. Their innovation could enable electric vehicles (EVs) to travel up to 50% farther on a single charge while improving safety and battery lifespan. The team employed graph neural networks to rapidly identify optimal materials for solid electrolytes and protective coatings, overcoming a major hurdle in solid-state battery development. This approach is orders of magnitude faster than traditional quantum chemistry methods, enabling quicker advancement in battery design. A key aspect of the research is the identification of protective coatings that shield the solid electrolyte from reactive lithium anodes and cathodes, which otherwise degrade battery performance and increase short-circuit risks. Using AI, the team discovered promising coating compounds such as Li3AlF6 and Li2ZnCl4 for the solid electrolyte Li10GeP2S12, a leading candidate material. This work not only enhances the durability and efficiency of solid-state batteries but also paves the way for safer, more durable, and higher-performing EVs and portable electronics, potentially reshaping the future of energy storage.
