▎ 摘  要

NOVELTY - The method involves preparing an electrode active material for a ultra-capacitor. A nitrogen and fluorine source is prepared. The nitrogen and fluorine source is co-doped into the electrode active material for ultra-capacitors by reacting nitrogen and fluorine sources with the electrode active material for ultra-capacitors, where the electrode active material comprises at least one group selected from among graphene, carbon nano-tubes and activated carbons. The nitrogen and fluorine source is ammonium fluoride, nitrogen trifluoride, tetrafluorohydrazine, difluoramine, ammonium fluoroborate and nitrosyl fluoride. USE - Method for manufacturing electrode active material for ultra-capacitor. ADVANTAGE - The method improves electrical conductivity of electrode active material, exhibits high output characteristics, and has high capacity retention rate of more than 90% under current density of greater than or equal to 50 mA/cm 2. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a high-power ultra-capacitor using an electrode active material for a capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method for manufacturing electrode active material for ultra-capacitor (Drawing includes non-English language text).
