NASA's project SABERS is testing a graphene battery that could be a game changer for aviation and EVs

NASA's SABERS (Solid-state Architecture Batteries for Enhanced Rechargeability and Safety) project, which has been going on for a few years under NASA’s “high risk, high reward” research program, aims to develop batteries with improved power density (preferably ones that could make electric flight feasible, which required around 480 watt-hour per kilogram).
