· JVASP-107549· LiSmS2

LiSmS2 is a lithium-samarium sulfide ceramic compound belonging to the family of rare-earth sulfide materials. This is a research-phase material primarily investigated for solid-state battery applications, where its ionic conductivity and chemical stability in lithium-based electrochemical systems make it a candidate for advanced electrolyte and electrode materials. While not yet in mainstream industrial production, compounds in this material family are valued by battery researchers seeking alternatives to conventional oxide ceramics, offering potential advantages in energy density and thermal stability for next-generation energy storage systems.
