Abstract
Disclosed is a method of producing lithium sulfide (LiS) without using hydrogen sulfide (HS) gas. Particularly, the method of producing lithium sulfide (LiS) includes preparing a starting material including a metal oxide by subjecting a mixed powder including an inorganic compound containing lithium and oxygen, a metal reducing agent, and sulfur (S) to synthesis reaction using mechanical force, preparing a mixed solution by mixing the starting material and a solvent, and obtaining a lithium sulfide (LiS) powder by removing the metal oxide from the mixed solution and then performing drying.
