POLARIZED ELECTRODE, MANUFACTURE THEREOF AND ELECTRIC DOUBLE LAYER CAPACITOR USING THE SAME

Japanese Patent JP2778425

B2

PURPOSE: To make possible the supply of an electric double layer capacitor with a large current by constituting it of an activated carbon/carbon composite material wherein thin holes having specified hole diameters occupy a specified volume.
CONSTITUTION: A polarized electrode 1 is constituted of an activated carbon/carbon composite material wherein thin holes of hole diameters 0.1 to 5.0μm occupy a volume of 0.1 to 1.2cc/g. The polarized electrodes in a pair impregnated with art electrolyte are opposed to each other with a separator 2 held between and conductive sheets are contact-bonded thereon from the opposite sides to be made current collectors 3. On the occasion, a polycarbonate gasket 4 is disposed around the polarized electrodes 1 so that the current collectors 3 on the opposite sides may not come into contact with each other. Next, a pair of polycarbonate supports 5 are disposed on the opposite sides of the current collectors 3, the current collectors 3 are held by these supports 5 and the gasket 4 and further epoxy resin is applied ore the peripheries of the gasket 4 and the supports 5 so as to seal up the electrolyte. Then, terminal plates 6 are contact-bonded on the current collectors 3 from the opposite sides, held further by fixing plates 7 and fixed at four places by bolts and nuts 8.
