1. A method of producing a carbon material composite containing graphite oxide and at least one surfactant selected from the group consisting of a nonionic surfactant, a cationic surfactant, and an amphoteric surfactant, the method comprising:
oxidizing graphite using sulfuric acid;
mixing an aqueous dispersion obtained through the oxidizing, the aqueous dispersion containing graphite oxide dispersed therein, and the at least one surfactant selected from the group consisting of a nonionic surfactant, a cationic surfactant, and an amphoteric surfactant; and
purifying the carbon material composite.
