摘要： A cylindrical electric double-layer capacitor includes a cylindrical sealed vessel housing an electrode roll and an electrolyte solution. The electrode roll is formed of a rolled superposed assembly having band-shaped positive and negative poles and two band-shaped separators sandwiching one of the band-shaped positive and negative poles. Each of the band-shaped positive and negative poles includes a band-shaped collector and a pair of polarizing electrodes formed in a laminated manner on opposite surfaces of the band-shaped collector. In a state in which the electrode roll has been accommodated in the sealed vessel along with the electrolyte solution, an outer diameter D1 of the electrode roll and an inner diameter D2 of the sealed vessel are brought into a relationship of D1=D2 by at least one of swelling of the polarizing electrodes caused by the electrolyte solution and expansion of the polarizing electrodes caused by an electrical charge. Thus, in the cylindrical electric double-layer capacitor, it is possible to avoid an increase in internal resistance, a reduction in a self-discharging characteristic and other like electrical characteristics.

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.
