Abstract: The present invention relates to a method for reforming the surface of a carbon fiber, which can be used as the carbon electrode of a redox flow battery, a carbon fiber having the surface thereof reformed thereby, and a carbon electrode and a redox flow battery including the carbon fiber having the surface thereof reformed thereby. The method for reforming the surface of a carbon fiber according to the present invention comprises the steps of: supporting the carbon fiber on a solvent containing a hydroxyl group; treating, with supersonic waves, the carbon fiber supported on the solvent containing a hydroxyl group; and thermally treating the carbon fiber treated with supersonic waves. The carbon fiber having the surface thereof reformed according to the present invention can improve the electrochemical properties of the carbon fiber by maximizing the specific surface area of the carbon fiber because the surface of the carbon fiber is reformed to be hydrophilic and has mesopores formed thereon. Therefore the carbon fiber having the surface thereof reformed according to the present invention can be used as the carbon electrode of a redox flow battery.

Abstract: PURPOSE: A method for preparing an anode active material is provided to easily prepare titanium oxide with a size of several nanometers in a nitrogen-doped porous carbon nanotube, and allow an appropriate control of the nitrogen content, the titanium oxide content, the pore size, the diameter of the carbon nanotube, and the size of titanium oxide. CONSTITUTION: A method for preparing an anode active material comprises the following steps. An electro-spinning solution is prepared by mixing a first solution in which a metal oxide precursor is dissolved, a second solution in which a polymer as a carbon nanotube precursor is dissolved, and an ionic liquid solution for nitrogen doping and forming of a porous structure (S10). The electro-spinning solution is electro-spun to prepare a composite material of metal oxide-nitrogen-porous carbon nanotube (S20). The composite material is thermally treated (S30). Further, an anode is formed by coating a current collector with a slurry in which the anode active material, a conducting agent, a binding agent, and a solvent are mixed.
