Lithium sulfide is the inorganic compound with the formula Li2S. This solid, which crystallises in the antifluorite motif, is described as the salt (Li+)2S2-. In 2005, lithium sulfide found use in batteries,ref|electronicsweekly.com the system being related to the sodium-sulfur battery.

Lithium sulfide is prepared by treating lithium with sulfur.ref|webelements.com This reaction is conveniently conducted in anhydrous ammonia. [Rankin, D. W. "Digermanyl Sulfide" Inorganic Syntheses 1974, XV, pages 182-184.] :16Li + S8 → 8Li2S
