Abstract: Surface fluorination process of lithium metal using elemental fluorine. Thereby, a uniform surface layer of LiF free of impurities is formed over the entire surface of the Li metal. This highly reproducible treatment can also be carried out on a large scale, making it possible to obtain a material which can be advantageously used as an anode in a lithium battery, since it ensures significantly higher performance than those obtained not only by using lithium metal as an anode, but also lithium metal anodes provided with a LiF layer, in which the formation of the LiF layer is formed in situ by organic or inorganic fluorine agents.
