▎ 摘　　要

NOVELTY - The electrode e.g. positively charged carbon composite electrode (7), has primary synthetic carbon provided with an irregular, nongraphitic structure, and secondary synthetic carbon made of graphene layers and polymeric binding agent, where electrodes specific capacity is determined by linear regression equations. The secondary synthetic carbon inside electrode composition formed by the graphene layers is carbide-derived carbon. A conducting adhesive layer is formed by mixture of conducting carbon nanopowder and electrochemically inactive organic polymer. USE - Carbon composite electrode e.g. positively charged carbon composite electrode and negatively charged carbon composite electrode, for an electric double-layer capacitor (EDLC). ADVANTAGE - The electrode has the carbide carbon nanopowder with high ultramicropore concentration and homogenous pore distribution developed preferably from carbide crystallites of large dimensions, so that carbon particles is obtained by kind of synthesis for preparing the electrodes with good conductivity and specific capacity and obstacle in preparing the electrodes is a coarse structure of an electrode surface, thus improving mechanical strength for carbon film and preventing separating of the carbon particles during electrochemical cyclisation in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a package of a carbon composite electrode.
