LI2S@C COATED LITHIUM METAL PRODUCT METHOD FOR THE PRODUCTION THEREOF AND USE

摘要

22822The invention relates to 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 SO or mixtures thereof. The method products according to the invention are used to produce lithium battery electrodes.
