Abstract: PURPOSE: A method is provided to effectively use the surface area of a carbon nano material and reduce the internal resistance of an electrode by permitting the carbon nano material to directly grow on the surface of a current collector. CONSTITUTION: A method is characterized in that a current collector contacts the mixture of a hydrogen and a carbon containing gas and a carbon nano material is deposited on the surface of the current collector. The deposition process is performed in the temperature of 400 to 1200 Deg.C for 1 to 60 minutes. The carbon nano material is selected from a carbon nanotube, a carbon nanofiber, and an amorphous carbon.
