· JVASP-35221· Li2SiSnS4

Li2SiSnS4 is a mixed-metal sulfide ceramic compound belonging to the family of lithium-based thiostannates, synthesized as a research material rather than a commercial product. This compound is being investigated primarily for solid-state electrolyte applications in all-solid-state lithium-ion batteries, where its ionic conductivity and chemical stability make it a candidate for next-generation energy storage systems that require improved safety and energy density compared to liquid electrolyte batteries.
