Abstract
Provided is a method for producing lithium sulfide based on a new dry method, by which lithium sulfide can be produced more easily at lower cost, and fine pulverization of lithium sulfide can be attempted. Suggested is a method for producing lithium sulfide (Li2S) for a solid electrolyte material for lithium ion batteries that is used as a solid electrolyte material for lithium ion batteries, the method including bringing lithium carbonate powder into contact with a gas containing sulfur (S) in a dry state, simultaneously heating the lithium carbonate, and thereby obtaining lithium sulfide powder.
