· JVASP-135364· LiSiS

LiSiS (lithium silicon sulfide) is an inorganic ceramic compound belonging to the sulfide ceramic family, characterized by ionic bonding between lithium, silicon, and sulfide ions. This material is primarily of research interest for solid-state battery electrolytes and ion-conducting ceramic applications, where its lithium-ion mobility and chemical stability make it a candidate for next-generation energy storage systems. LiSiS represents an emerging class of lithium superionic conductors that could enable higher energy density batteries with improved thermal and chemical stability compared to conventional liquid electrolytes.
