Application

Lithium Sulfide is primarily used in the development of solid-state batteries, where it serves as a key component in sulfide-based solid electrolytes due to its high ionic conductivity and compatibility with lithium metal anodes. It is also employed in the synthesis of cathode materials for next-generation lithium-sulfur (Li-S) batteries, enabling higher energy densities and improved cycle life. Researchers utilize Li₂S to study interfacial stability and electrochemical performance in energy storage systems. Additionally, it finds applications in specialty glass and ceramic formulations where sulfur incorporation is required.
