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, the system being related to the sodium-sulfur battery.
Lithium sulfide is prepared by treating lithium with sulfur. This reaction is conveniently conducted in anhydrous ammonia.[1]
- 16Li + S8 → 8Li2S
