Electrochemical method for converting amorphous carbon into graphite

The invention relates to an electrochemical method for converting amorphous carbon into graphite. The method comprises the following steps: preparing an amorphous carbon material into a solid cathode, taking the graphite or other conductive material as an anode, controlling the pressure of a tank or the potential of the cathode in molten salt of MX (m-xylene) for electrolysis, and converting the amorphous carbon into graphitized carbon. The method is simple in process, low in reaction temperature, free from a catalyst and low in cost; products can be graphite powder, two-dimensional nanosheets, one-dimensional nanofibers, hollow nanospheres or the like; the method has a wide application prospect in the fields of graphite structure materials, energy storage, catalysis, adsorption, separation and the like.
