· JVASP-135380· LiY2S2

LiY2S2 is an inorganic ceramic compound belonging to the lithium yttrium sulfide family, representing a mixed-metal sulfide with potential applications in solid-state electrochemistry and advanced ceramics. This material is primarily investigated in research contexts for solid electrolyte applications in all-solid-state batteries, where sulfide-based ceramics offer high ionic conductivity and wide electrochemical stability windows compared to oxide counterparts. Engineers would consider this compound for next-generation energy storage systems where ceramic electrolyte materials can enable higher energy density, improved safety, and extended cycle life in lithium-ion and solid-state battery designs.
