Document Type and Number:
WIPO Patent Application WO/2022/186379
Kind Code:
A1
Abstract:
Provided is a method for more suitably producing lithium sulfide having a high ion conductivity without producing by-products. This method for producing lithium sulfide involves a temperature increasing step (step S14) in which lithium sulfate put into a furnace is reduced, in an atmosphere with a reduced pressure of 0.05 MPa or less, in the state where the lithium sulfate is heated to a temperature higher than 700°C.
