· JVASP-155429· LiGeS2

LiGeS2 is an inorganic ceramic compound composed of lithium, germanium, and sulfur, belonging to the family of lithium-based mixed-anion ceramics. This material is primarily of research interest for solid-state electrolyte and ionic conductor applications, where its sulfide-based structure offers potential advantages in ion transport compared to oxide ceramics. LiGeS2 is explored in advanced battery systems and solid-state energy storage devices, though it remains largely in the developmental stage rather than high-volume production.
