Fluorographite is a kind of graphite interlayer compound in which fluorine atoms are inserted into graphite layers. Fluorographite is a powder solid, and its color gradually changes from black to gray to white with the increasing of F/C ratio. Fluorographite has been widely used in solid lubrication, corrosion protective and antifouling coatings Li-CFx batteries and other fields due to the merits of extremely low surface energy, excellent chemical and thermal stability, outstanding lubrication performance and super theoretical specific capacity. Fluorographite can be subdivided into fluorinated flake graphite, fluorinated spherical graphite, fluorinated expanded graphite and fluorinated nano-graphite according to different raw materials.
