Sulfide-based all-solid-state batteries (ASSBs), which use a solid electrolyte instead of a liquid one, are emerging as a promising way to overcome the safety and energy-density limitations of conventional lithium-ion batteries. However, a major obstacle to their practical use is the poor chemical compatibility at the interface between the cathode active materials (CAMs) and sulfide-based solid electrolytes.
