Graphite fluoride is classified into (CF) n and (C 2F) n types from the structure and composition. (CF) n has been already synthesized industrially in fairly large quantities and utilized as an excellent cathodic depolarizer in lithium organic electrolyte batteries. Furthermore, many researches on the application have been carried out in comprehensive industrial fields such as lubricant, water repellent, mold release agent, etc. On the other hand, a new type of graphite fluoride, (C 2F) n, is also expected as the promising new material in a wide variety of industrial fields. However, it had been not produced to date on an industrial scale. Central Glass Co., Ltd. has further developed the industrial technology for mass production of (C 2F) n and has been brought it to the stage of plant construction, in addition to (CF) n. In this paper, the properties and the applications of (C 2F) n will be reported in comparison with those of (CF) n.
