Solid electrolytes open doors to solid-state batteries
Japanese scientists have synthesized two crystal materials that show great promise as solid electrolytes. All-solid-state batteries built using the solid electrolytes exhibit excellent properties, including high power and high energy densities, and could be used in long-distance electric vehicles.
High power batteries are desirable for numerous applications, including the electric vehicles of the future. These batteries must be rechargeable, remain safe to store and use at variable temperatures, and retain charge for a considerable length of time. Now, Yuki Kato and Ryoji Kanno in collaboration with colleagues from Toyota Motor Corporation, Tokyo Institute of Technology and High Energy Accelerator Research Organization Japan (KEK), have successfully designed and trialled novel, high power all-solid-state batteries with promising results. ….
