Solid-state batteries promise high energy storage with enhanced safety but suffer from contact loss at the lithium (Li) metal anode-solid electrolyte interface as Li is stripped into ionically-conducting solid electrolyte. Contrary to prevailing view that arises void formation in this interface, we demonstrate, cells garnet electrolytes, it instead deposition of insulating impurities within electrode onto interface. These form a porous layer, and an imposed stack pressure required for creep...
