Abstract
The invention relates to a novel method for producing a carbon-doped lithium sulfide powder, according to which elementary lithium is reacted with elementary sulfur and/or a sulfur-containing compound selected from the group containing CS, COS, SOand SO, in a liquid state, in an aliphatic or cycloaliphatic hydrocarbon solvent. The products of the method according to the invention are used to produce lithium battery electrodes or a lithium-ion-conducting solid.
