Graphite fluoride is a new type of inorganic fluoride material, a white solid powder. As a new derivative of graphene, it not only maintains the high strength of graphene, but also has some excellent properties different from graphene due to the introduction of fluorine atoms, such as reduced surface energy, enhanced hydrophobicity, and band gap widening, and other novel interfaces and physical and chemical properties. At the same time, graphene fluoride is resistant to high temperatures, corrosion, friction, chemically stable, and has excellent lubricity. It can be used as a cathode material in Lithium carbon fluoride batteries.
