Title:
POLARIZABLE ELECTRODE FOR ELECTRIC DOUBLE LAYER CAPACITOR, METHOD FOR MANUFACTURING SAME AND ELECTRIC DOUBLE LAYER CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2004/055844
Kind Code:
A1
Abstract:
An electric double layer capacitor electrode which has a low collector resistance and a high capacitance even when it is provided with an electrode active material layer containing more activated carbon is disclosed. A method for manufacturing such an electric double layer capacitor electrode and an electric double layer capacitor are also disclosed. The electric double layer capacitor is characterized by sealing a polarizable electrode wherein a pattern of electrode active material layer is formed on at least one surface of a collector through intermittent application by a die-coating method or a comma reverse method and the pattern is composed of electrode active material layers arranged at intervals at least in the longitudinal direction of the collector, at least a pair of polarizable electrodes, a separator and an electrolytic solution in a case.
