Abstract
A plurality of polarizable electrodes, a laminate of a collector layer, a polarizable electrode layer of a porous sheet, and a carbon-based conductive material interposed therebetween, are disposed in a row arrangement, interposing separators between the polarizable electrodes, and an electrolyte is packed between said polarizable electrodes and said separators; the carbon-based conductive material penetrating into the voids in the polarizable electrode layers. A process is provided whereby the polarizable electrode is manufactured by applying a conductive material solution to the collector and/or polarizable electrode sheet surface, superposing the two, and then evaporating out the dispersion medium of the conductive material solution.
