摘要： 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.

摘要： A method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas.The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.

摘要： A method for preparing a lithium ion conductive sulfide, which is capable of independently controlling the elemental ratio of lithium (Li), phosphorus (P), sulfur (S), etc, is provided. The method for preparing a lithium ion conductive sulfide can provide a lithium ion conductive sulfide having a crystal structure and an anion cluster distribution distinguished from those of existing ones.
