Solid-state batteries use solid electrolytes, not liquid, which results in a higher energy density than traditional lithium-ion chemistries. After years of development, they promise to be the next big trend in electric vehicle technology.
Benefits include faster charging, greater energy density, longer cycle life and thermal stability. Pilot production lines are starting to emerge and mass-production could start by 2023. Automakers such as BMW, Daimler, Ford, Nissan, Toyota and Volkswagen are leading the way, in addition to start-ups such as ProLogium, QuantumScape and Solid Power. Electrovaya, LG, Panasonic, Samsung and other traditional battery manufacturers are also actively pursuing the technology.
