摘要： An electric double-layer capacitor includes a cell structure formed by laminating basic cells in series one on another. Each of the basic cells includes a pair of collectors, a separator disposed between said collectors, gaskets disposed at peripheral edges of said pair of collectors and said separator to define a pair of closed spaces, and a pair of polarizable electrodes which are disposed in said closed spaces defined by said collectors, said separator and said gaskets, respectively and which contain an electrolytic solution. The basic cells are laminated one on another with a back of each of said collectors opposed to said polarizable electrode serving as a connection surface. The electric double-layer capacitor further includes a lead terminal/electrode plate assembly having electrode plates bonded to the collectors located at opposite ends of the cell structure through conductive bond layers. At least one of interfaces between the collectors included in said cell structure has a surface shape based on a rugged surface shape of the surface of the polarizable electrode contacting with and opposed to at least one of the two collectors forming such interface. Thus, in the electric double-layer capacitor, a lower ESR can be realized both at an initial stage of the service of the capacitor and after the service of the capacitor for a long period.

摘要： A component cell of an electric double layer capacitor is fabricated by forming first and second half portions of the cell. In each of the half portions a polarized electrode impregnated with electrolyte is pasted to a collector electrode so that a stepped portion is formed on the periphery of the collector electrode. A gasket is attached to the stepped portion of each half portion, and a center gasket is attached to the periphery of a separator which is placed between the first and second half portions. Pressure is then applied to the first and second half portions of the cell in directions towards each other at an elevated temperature so that all gaskets are thermally joined together. A plurality of such component cells are stacked in a layered structure and sealed in a package.

摘要： Anodized films are formed at both surfaces of an aluminum base and, at the center portion on each side of the aluminum base, a solid electrolyte layer of a conductive polymer, a graphite layer, and a metal layer are stacked in the order, thereby forming a rectangular cathode portion. An insulator layer is formed at the peripheries of four sides of the cathode portion and, further, an anode lead frame is provided at the peripheries of four sides of the upper insulator layer, thereby forming an anode portion. Openings are formed at four corners of the insulator layer or the anode portion, thereby establishing electrical connection between the cathode portions on both sides of the aluminum base. By setting the ratio of a total region, occupied by the openings, of the cathode portion to 25% or less, the ESL of a capacitor can be suppressed low even when the openings are provided.

摘要： A solid electrolytic capacitor includes a porous sintered body made of a valve-acting metal and embedded with part of an anode lead having a protruding portion, a solid electrolyte layer formed in contact with a dielectric layer formed in the porous sintered body, a mounting anode terminal member, a mounting cathode terminal member, and an insulating casing resin. The capacitor further includes a small piece of a metal frame made of a valve-acting metal. This small piece of the metal frame is formed integrally with the protruding portion of the anode lead by cutting, after the anodic oxidation, the metal frame to which the protruding portion of the anode lead is fixed by resistance welding. The small piece of the metal frame and the mounting anode terminal member are connected together by wire bonding so that the anode lead and the mounting anode terminal member are electrically connected together.

摘要： The capacitor element includes as an anode an aluminum foil in the form of a thin plate, an oxide layer formed as a dielectric on the surface of the anode, and a conductive polymer layer formed as a cathode on the dielectric. The capacitor is formed by drawing terminals in arrays from the capacitor element. On the upper side of the capacitor element is provided an embossed copper foil 11 for suppressing deformation of the capacitor element. The anode terminals and the cathode terminals are drawn to the lower side of the capacitor element. The anode terminals and the cathode terminals are alternately formed at the same pitch in the x-direction and the y-direction, so that the heteropolar terminals are disposed at the adjacent positions with respect to any one of the terminals.
