1. A method for preparing a carbon material, comprising:
connecting two ends of an electrically conductive medium to an anode and a cathode, respectively; and
applying a voltage to the electrically conductive medium to form an electrically conductive path in an oxygen-free environment containing a carbon source and a catalyst to obtain the carbon material, wherein the electrically conductive medium is a solid substrate;
wherein the carbon material is obtained on a surface of the solid substrate; and
wherein the carbon source is selected from the group consisting of ethanol and ethylene glycol, the catalyst is Fe, the electrically conductive medium is carbon fibers, the oxygen-free environment is provided by one selected from the group consisting of ethanol and ethylene glycol, and the formed electrically conductive path has a current of 1.5-5 A and a voltage of 10-40 V.
