· JVASP-3084· Na3SbS4

Na3SbS4 is an inorganic ceramic compound belonging to the sulfide family, specifically a sodium antimony sulfide material. This is a research-stage compound under investigation for solid-state electrolyte applications in battery technology, where sulfide-based ceramics are valued for their ionic conductivity and potential to enable next-generation energy storage systems. Engineering interest centers on its role as an alternative to oxide ceramics in all-solid-state battery designs, where improved lithium-ion or sodium-ion transport and chemical stability against electrode materials could offer higher energy density and safety compared to conventional liquid electrolytes.
