Abstract
A particulate lithium metal/lithium sulfide composite material, to a method for producing a LiS@C-coated lithium metal product, and to the use of said lithium metal product. The particulate lithium metal/lithium sulfide composite material has a core-shell morphology, the shell of which is made of a lithium sulfide containing C and the core of which is made of metal lithium. According to the method, the particulate lithium metal/lithium sulfide composite material is produced by reacting melted, drop-shaped lithium metal in a hydrocarbon solvent with a sulfur source selected from the group CS, S, HS, COS, SO, SOor mixtures thereof. The method products according to the invention are used to produce lithium battery electrodes.
