· Li1 Sc1 S2

Lithium scandium sulfide (Li₁Sc₁S₂) is an ionic semiconductor compound combining rare-earth and alkali-metal elements in a sulfide host lattice. This material is primarily of research interest for solid-state electrolyte and energy storage applications, where its ionic conductivity and chemical stability are being explored as an alternative to conventional lithium-ion architectures. The combination of lithium and scandium cations offers potential advantages in lithium-ion transport and structural rigidity, making it a candidate compound in the search for safer, higher-performance solid electrolytes for next-generation batteries.
