POLARIZABLE ELECTRODE FOR ELECTRIC DOUBLE-LAYER CAPACITOR, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polarizable electrode, that has a low internal resistance value per prescribed projection area of an electric double-layer capacitor, a large capacitance per a prescribed volume and superior fracture strength, and to provide method of manufacturing the same. SOLUTION: The polarizable electrode of the present invention is manufactured, through the formation of a mixed power by dry-blending of activated carbon powder, conductive auxilary power and polymer resin powder containing fluorine with a lamellar structure and then compressing and molding this mixed powder into a sheet. In this plarizable electrode manufactured using this method, activated carbon is connected, so as to be held by three-dimensional structure composed of microfilaments of the polymer resin, containing fluorine formed by fracture of lamellar structure. Therefore, a polarizable electrode having superior fracture strength can be obtained.
