· JVASP-35975· LiScS2

LiScS2 is a lithium scandium sulfide ceramic compound belonging to the family of solid electrolyte materials. This material is of primary interest in solid-state battery research, where it functions as a ceramic electrolyte to conduct lithium ions between battery electrodes while maintaining electronic insulation. LiScS2 represents an emerging class of materials designed to overcome limitations of conventional liquid electrolytes—offering improved thermal stability, safety, and potential for higher energy density—though it remains largely in the development and optimization phase rather than in widespread commercial production.
