Li2BS2 is an experimental lithium borate sulfide ceramic compound belonging to the class of mixed-anion ceramics that combine boron, sulfur, and lithium chemistry. This material is primarily of research interest for solid-state electrolyte applications in next-generation lithium-ion and lithium-metal batteries, where its ionic conductivity and stability at interfaces make it attractive compared to conventional liquid electrolytes. The mixed-anion structure represents an emerging strategy to achieve higher ionic conductivity while maintaining mechanical and thermal stability, positioning Li2BS2 within the broader family of superionic conductors being developed to enable safer, higher-energy-density battery systems.
