Solid lithium-air battery hits 4x energy, breaks room-temperature performance barrier

A lithium-air battery that rivals gasoline in energy density may be the game-changer EVs have been waiting for. ================================================================= In a major leap toward next-generation energy storage, researchers have created a lithium-air battery that could one day rival gasoline in energy density, offering up to four times the capacity of today’s lithium-ion batteries. If realized at scale, such a breakthrough could transform everything from electric vehicles to grid storage. This cutting-edge development, led by scientists at the Illinois Institute of Technology and Argonne National Laboratory, hinges on achieving a four-electron chemical reaction—a feat never before accomplished in a lithium-air battery...
