  • METHOD OF PRODUCING LITHIUM SULFIDE WITHOUT USING HYDROGEN SULFIDE GAS
    Publication number: 20240166515
    Abstract: Disclosed is a method of producing lithium sulfide (Li2S) without using hydrogen sulfide (H2S) gas. Particularly, the method of producing lithium sulfide (Li2S) 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 (Li2S) powder by removing the metal oxide from the mixed solution and then performing drying.
