The invention relates to new carbons containing fluorine. The carbons containing fluorine are obtained from a graphite or a mosaic textured graphitisable compound containing carbon. As a first step, the graphite or the carbon-containing compound is reacted with a gaseous mixture (HF+F2) in presence of an MFn fluoride at a temperature range between 15° C. and 80° C., M representing an element selected among I, Cl, Br, Re, W, Mo, Nb, Ta, B, Ti, P, As, Sb, S, Se, Te, Pt, Ir, and Os and n representing the valency of the element M, with n>=7. As a second step, the compound obtained at the end of the first step is reacted with fluorine for 1 to 20 hours at a temperature range between 20° C. and 400° C. The invention is useful as an active electrode material. |
