Abstract
A particulate lithium metal composite materials having a layer containing phosphorous and a method for producing said phosphorous-coated lithium metal products, characterized in that melted, droplet-shaped lithium metal is reacted in a hydrocarbon solvent with a phosphorous source that contains the phosphorous in the oxidation stage 3, and use thereof for the pre-lithiation of electrode materials and the production of battery anodes.
