PURPOSE: A method for introducing an oxygen functional group to the surface of a carbon material is provided to avoid a post treatment process for removing foreign materials due to simple and safe an oxygen functional group introduction process. CONSTITUTION: A method for introducing an oxygen functional group to the surface of a carbon material comprises the steps of: (i) installing a carbon material in at least one electrode of a working electrode or counter electrode; (ii) dipping the carbon material in electrolyte in the state where the working electrode or counter electrode are adhered; and (iii) connecting the working electrode or counter electrode to a DC power supply to perform electrolytic oxidation.
