Y verify ( what is ? ) Infobox references Lithium sulfide is the inorganic compound with the formula Li S. It crystallizes in the antifluorite motif, described as the salt ( Li ) S. It forms a solid yellow - white deliquescent powder. In air, it easily hydrolyses to release hydrogen sulfide ( rotten egg odor ). Contents 1 Preparation 2 Reactions and applications 3 References 4 External links Preparation Lithium sulfide is prepared by treating lithium with sulfur. This reaction is conveniently conducted in anhydrous ammonia. 2 Li + S → Li S The THF - soluble triethylborane adduct of lithium sulfide can be generated using superhydride. Reactions and applications Lithium sulfide has been considered for use in lithium - sulfur batteries.
