摘要： An electric double-layer capacitor includes a plurality of electrode elements each having a current collector, a polarized electrode disposed on a surface thereof, and a strip-like current collecting lead extending from an end of the current collector. The electrode elements are stacked as alternately belonging to respective polarities, and the current collecting leads of the electrode elements are stacked into lead assemblies of the respective polarities. A separator is interposed between the stacked electrode elements, and the lead assemblies are connected respectively to electrode terminals. The lead assemblies of respective polarities serve as respective connectors connected to the electrode terminals. Each of the connectors has a flat joint region as at least a portion thereof. The current collecting leads of each of the lead assemblies are integrally joined to each other by the flat joint region by ultrasonic welding before the connector is connected to the electrode terminal. The connectors are joined to the electrode terminals, respectively, through the respective joint region by electron beam welding or laser beam welding.

摘要： An electric double-layer capacitor housing has a bottomed outer case for accommodating an electric double-layer capacitor therein, a lid closing an open end of the bottomed outer case, the lid having a through hole defined therein, an electrode terminal mounted in the through hole in the lid for electrically connecting the electric double-layer capacitor in the bottomed outer case to an external circuit, and an insulative sealing member interposed between the lid and the electrode terminal and sealing the through hole. The electrode terminal includes a terminal body, a projecting rod extending from the terminal body, an outer sleeve spaced radially outwardly from the projecting rod, a tapered portion spreading radially outwardly and downwardly, and a flange extending radially outwardly from the tapered portion. The insulative sealing member includes a tubular member fitted over the terminal body and the outer sleeve of the electrode terminal, and a skirt extending radially outwardly from a lower end of the tubular member. The lid includes a circumferential surface defining the through hole, a first convex surface contiguous to an upper end of the through hole, a first concave surface extending around the through hole, a second convex surface contiguous to a lower end of the through hole, and a second concave surface extending around the through hole.

摘要： A current collector for use in an electric double-layer capacitor is constructed such that it is held in intimate contact with the electrodes thereby reducing the internal resistance and providing for better charging and discharging characteristics. The current collector includes an electrically conductive metal foil having a plurality of through holes defined therein and a plurality of pointed bars projecting from edges of each of the through holes perpendicularly to the electrically conductive metal foil. The pointed bars extend through electrodes disposed on opposite surfaces of the current collector. Distal end portions of the pointed bars are bent over against the outer surfaces of the electrodes. The bent distal end portions hold the electrodes under pressure against the current collector so that the current collector and the electrodes are tightly fastened together. Preferably, the electrically conductive foil includes aluminum foil and each of the electrodes contains activated carbon.
