Embodiment Construction

[0021] figure 1 It is a partially cutaway perspective view of a capacitor using the capacitor electrode assembly according to the embodiment of the present invention. First, edge reference figure 1 , an example of a capacitor using the capacitor electrode assembly of the present embodiment will be described. This capacitor has a capacitor element 1 , an electrolytic solution (not shown) impregnated at least in the capacitor element 1 , a case 2 , and a sealing member 3 .

[0022] The bottomed cylindrical case 2 is made of aluminum. The case 2 accommodates the capacitor element 1 and the electrolytic solution. A sealing member 3 made of rubber is fitted into the opening of the case 2 . That is, the sealing member 3 seals the opening of the case 2 . The vicinity of the opening end of the case 2 is constricted, and the case 2 is firmly sealed by compressing the sealing member 3 inwardly. The case 2 and the sealing member 3 constitute an outer package for accommodating the...

Abstract

Disclosed is an electrode structure for capacitors which comprises a current collector having conductivity, a protective layer formed on the current collector, an anchor coat layer formed on the protective layer, and a polarizable electrode layer formed on the anchor coat layer. The protective layer contains an oxyhydroxide, and the anchor coat layer contains conductive particles.

Description

technical field [0001] The present invention relates to a capacitor electrode body used in various electronic equipment, electric equipment, industrial equipment, automobiles, etc., a manufacturing method thereof, and a capacitor using the electrode body. Background technique [0002] In recent years, from the viewpoint of environmental protection, capacitors that assist power when driving vehicles or construction machines have been developed. Capacitors for such applications are required to have a large capacitance per unit volume and a small internal resistance. That is, high energy density and high output density are required. [0003] In order to reduce the internal resistance of the capacitor in response to this demand, it is important to have a structure with high adhesion between the current collector and the polarizable electrode material. As a polarizable electrode material, generally, carbon-based powder particles having good conductivity such as activated carbon...
