The invention provides materials capable of giving electrodes which are reduced in the capacity loss due to an irreversible capacity in the initial cycle in the charge and discharge cycle test as compared with electrodes made by using conventional materials; and a process for the production thereof. A carbon composite material consisting of a carbon material and a coating made of a metal oxide on the surface of the carbon material, wherein the metal oxide is an Fe-containing metal oxide; a carbon composite material as described above, wherein the carbon material is mesoporous carbon; a carbon composite material as described above, wherein the Fe-containing metal oxide is Fe2O3; and a process for the production of the carbon composite materials which comprises the steps (a) and (b): (a) the step of using an anode, a cathode with a carbon material set on the surface thereof, and an electrolytic solution consisting of an aqueous solution containing Fe and depositing Fe on the surface of the carbon material through electrolysis to obtain an Fe-coated carbon material; and (b) the step of heating the Fe-coated carbon material in an oxygen-containing atmosphere. |
