Scientists have discovered a way to build next-generation batteries for electric cars that do not lose any capacity, even after hundreds of charging cycles. Solid-state batteries have been hailed as “game-changing” for their potential to overcome the technical limitations of lithium-ion battery packs that are currently used to power the majority of consumSolid-state batteries have been described as the “next big thing” in battery development by one of BMW’s top engineers. er electronics – from smartphones to electric cars. However, until now solid-state batteries have faced their own limitations relating to durability. Repeated charges can cause irreversible damage to the interface between the electrodes and the electrolyte, making them inappropriate for commercial use. The new battery was able to retain its capacity of 300 mAh with no degradation over hundreds of charge-discharge cycles in lab tests by combining the positive electrode with an appropriate solid electrolyte and negative electrode.
