ELECTRIC DOUBLE LAYER CAPACITOR AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2005/064632

A1

An electric double layer capacitor (10) comprises a cell (12), a pair of generally planar conductors (22, 24) and a sealing member (26). The cell (12) comprises a pair of coated electrodes (14, 16) which are composed of a pair of plate-like collector layers (14A, 16A) and active material layers (14B, 16B) formed by applying a coating liquid containing an active material to surfaces of the collector layers (14A, 16A) opposing to each other, a separator (18) interposed between the active material layers (14B, 16B) of the coated electrodes (14, 16), and an electrolyte solution (20) filled between the coated electrodes (14, 16) and the separator (18). The conductors (22, 24) are larger than the cell (12) and respectively arranged on the outer sides of the cell (12) in the thickness direction so that the cell (12) is sandwiched between the conductors (22, 24), and the sealing member (26) is arranged between peripheral portions (22A, 24A) of the conductors (22, 24) which are located around the cell (12) for hermetically sealing the cell (12) along the periphery thereof.
