ACTIVATED CARBONACEOUS STRUCTURE AND ELECTRIC DOUBLE- LAYER CAPACITOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an activated carbonaceous structure which can be improved in the charging density of activated carbon powder and reduced in internal resistance and forms a polarized electrode of an electric double-layer capacitor with large electrostatic capacitor through short-time charging. SOLUTION: The electric double-layer capacitor 11 is manufactured by arranging a couple of polarized electrodes 12 and 12 impregnated with an electrolytic solution, in an activated carbonaceous structure formed by charging coconut shell activated carbon powder 2 of 0.1 to 0.4 r1 in mean particle size (r2 ) in phenol-resin based activated carbon powder 2 to 20 to 50μm in mean particle size (r1 ) across a separator 13, and also by arranging charge collectors 14 and 14 on the external surfaces of the polarized electrodes 12 and 12.
