Abstract
A method for producing lithium sulfide includes: a preparation process (step S12) at which a raw material and a reducing agent are charged into a furnace, the raw material being mainly composed of lithium sulfate having a property of weight loss of 5% or more to 25% or less upon heating to 120° C.; and a temperature raising process (step S14) at which the raw material and the reducing agent are heated in the furnace to raise the temperature.
