<p>PROBLEM TO BE SOLVED: To realize an electric double-layered capacitor which is lessened in inner resistance by a method wherein two electrode materials which are each possessed of a carbon electrode layer and a polar solvent swelling resin layer are wound or laminated making the resin layers confront each other into a capacitor device, and the capacitor device is impregnated with drive electrolytic solution. SOLUTION: Polytetrafluoroethylene, activated carbon, and carbon black are kneaded well into slurry, and the slurry is applied on an aluminum etched foil 3, then dried up, and pressed into a carbon electrode 2. Polyvinylidene fluoride (PVDF) is dissolved into N-methylpyrrolidone, N-methylpyrrolidone loaded with PVDF is applied on the carbon electrode 2 and then dried up, polar solvent swelling resin is formed into a separator layer 1, and the carbon electrode 2 and the separator layer 1 are joined into an electrode of integral structure. The electrode is cut into a belt, a lead terminal is provided to the aluminum surface, the electrodes are wound together with a PDF film making the swelling resin surface 1 confront each other and come into contact with the aluminum surface for the formation of an electric double-layered capacitor element. The capacitor element is impregnated with an electrolytic solution.</p> |
