    • A method for reforming the surface of natural graphite is provided to increase the surface of the natural graphite easily, by growing carbon nanofibers on the surface of the natural graphite in a vine type before reforming the surface of the natural graphite. Metal catalysts are uniformly adsorbed on the surface of natural graphite. The metal catalysts comprises metal salt, metal oxide, metal chloride, metal nitride, or precursors thereof, which contain at least one metal element selected from Fe, Co, Ni, Cu, Ti, Sn, Si, Ge, Pb, and In. The metal catalysts are heated at 400-600°C under an inert gas ambience, thereby immobilizing the catalysts on the surface of the natural graphite. Carbon nanofibers are vapor-grown on the surface of the natural graphite in a vine type at 500-650°C by using a mixture gas of at least one carbon source, which are selected from carbon monoxide, methane, acetylene, ethylene, and propane. The surface of the natural graphite on which the carbon nanofibers are vapor grown is oxidized at 200-400°C. Further, the inert gas is a mixing gas of nitrogen, argon, helium containing hydrogen.
