Lithium Sulfide, Powder, 99.9%, -1250 mesh

Lithium sulfide is used as a cathode material in lithium-sulfur batteries and as a precursor for synthesizing sulfide-based solid-state electrolytes.

It serves as a key component in the development of solid-state lithium electrolytes, particularly thio-LISICON and glass-ceramic types, to improve ionic conductivity and safety.
