  • Multi-layer type electric double-layer capacitor
    Patent number: 6522523
    Abstract: The invention provides an electric double-layer capacitor comprising a bipolar interelectrode formed by bonding a collector to a carbon electrode with no adhesive put therebetween. The electric double-layer capacitor is so designed that a plurality of combinations of an intermediate electroconductive polymer composite electrode and a separator placed in layers between a pair of terminal electroconductive polymer composite electrodes, wherein; the intermediate electroconductive polymer composite electrode is composed of an electroconductive sheet made of a polymer substance to which electroconductivity is imparted and which has an apparent melt viscosity of from 300 to 3,000,000 poises, and a carbon electrode heat-sealed to at least one surface of the sheet, and the carbon electrode and the separator contain an electrolytic bath infiltrated thereinto.
