▎ 摘　　要

NOVELTY - The method involves preparing a nitrogen source solution. The nitrogen source solution is reacted with the electrode active materials. The obtained material is doped with nitrogen by performing hydrostatic pressurizing process to obtain electrode material. The material is selected from graphene, carbon nanotubes and activated carbons. The nitrogen source is urea, melamine, polyacrylonitrile, polyaniline, polypyrrole, polyrhodanine, purine, Adenine, Guanine, Hypoxanthine, Xanthine and/or Theobromine. A separator is disposed between a cathode and an anode to prevent a short circuit between the anode and cathode, and electrolyte is electrolyte-regnated into the anode. USE - Method for producing electrode active material useful for high-power ultra-capacitor. ADVANTAGE - The electrical conductivity of the electrode active material is improved. The high power characteristics are realized by facilitating charge transfer in an electrolyte solution. The capacity retention rate of the high-power ultra-capacitor is increased. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the Method for producing electrode active material useful for high-power ultra-capacitor.
