Li4 S2 O8

Li₄S₂O₈ is an experimental lithium sulfate-oxide ceramic compound under investigation for advanced energy storage and solid-state electrolyte applications. While not yet commercially established, this material belongs to the family of lithium-based ionic conductors being developed as potential solid electrolytes for next-generation lithium-ion and lithium-metal batteries, where it could offer improved safety, energy density, and thermal stability compared to conventional liquid electrolytes. The sulfate-oxide composition positions it as a candidate for high-temperature ceramic applications requiring both ionic conductivity and mechanical stability.
