摘要： A capacitor comprises a capacitor element having electrode foils on the anode side and the cathode side laminated via separators, connecting parts of terminal components being disposed inside a laminated portion of the electrode foils and the separators, the connecting parts being connected to the electrode foils on the anode side and the cathode side; and a case that includes a storage part storing the capacitor element and having an opening portion sealed by a sealing body, that has a crimped part crimped from the outside of the storage part toward a side surface of the capacitor element, and that holds the capacitor element with the crimped part. The case is crimped to form the crimped part while avoiding a position at which the electrode foils of the capacitor element in the storage part overlap with tip portions of the connecting parts of the terminal components. The vibration resistance of the capacitor element can be consequently improved to prevent a damage of the terminal components and achieve the stability of operation of the capacitor.

摘要： Disclosed is a negative electrode active material which has a high capacity and good cyclability. The negative electrode active material comprises nanosize carbon particles and nanosize tin dioxide particles that are supported in a high-dispersion state on the nanosize carbon particles. The negative electrode active material has a high discharge capacity because of the reversible progress of a conversion reaction of tin dioxide (SnO 2 +4Li + +4e - †’ 2Li 2 O+Sn) therein. In a charge-discharge cycle test within a voltage range of 0 to 2 V vs. an Li/Li + electrode, the negative electrode active material shows a discharge capacity retention rate of about 90% even after 500 charge-discharge cycles at the rate 1C, which indicates excellent cyclability. Therefore, the negative electrode active material can be suitably used in a lithium ion secondary battery and a hybrid capacitor.

摘要： Disclosed are an aluminum electrolytic capacitor having low impedance properties and a long service life, and an electrolytic solution which enables to give such capacitor. The electrolytic solution contains a solvent containing water, a phosphorus oxoacid ion-generating compound which can generate a phosphorus oxoacid ion in an aqueous solution, and a chelating agent which can coordinate with aluminum to form an aqueous aluminum chelate complex. The electrolytic solution further contains a compound selected from the group consisting of azelaic acid and an azelaic acid salt, and a compound selected from the group consisting of formic acid, a formic acid salt, adipic acid, an adipic acid salt, glutaric acid and a glutaric acid salt. The content of azelaic acid and/or the azelaic acid salt is at least 0.03 moles per kg of the solvent. When the electrolytic solution is used in an electrolytic capacitor which utilizes an anode having an aluminum oxide film containing phosphorus in an amount of 30 to 150 mg per unit CV product in terms of phosphoric acid, the service life of the capacitor is remarkably prolonged.

摘要： A cathode foil and an anode foil, with an oxidized film layer formed on the surface and a separator interposed therebetween, are wound together to form a capacitor element, and prior to subjecting the capacitor element to chemical repair the content of the binder in the separator is adjusted to 10 to 20% with respect to the total weight of the separator. After the chemical repair, the capacitor element is immersed in mixed liquid prepared by mixing a polymerizable monomer and an oxidizing agent together with a predetermined solvent, a polymerization reaction of the electroconductive polymer is induced in the capacitor element, and a solid electrolyte layer is formed. The capacitor element is then inserted in an outer case; sealing rubber is mounted in the open-end portion and sealed with a tightening operation; and the unit is thereafter aged to form a solid electrolytic capacitor.

摘要： A capacitor element (20), in which a bipolar electrode foil connected with a lead terminal (10) is wound through a separator, is stored in a bottomed cylindrical outer case (30) made of aluminum or the like. A tube (100) made of a flexible material is movably set to the outer periphery of the round bar (12) of the lead terminal and the tube-provided lead terminal is drawn outward through a sealing body (110) set on the inner periphery of the opening of the outer case (30). The sealing body is constituted so that an elastic ring (113) made of a flexible material is set on the outer periphery of a sealing plate (112) made of a hard material harder than the tube. The tube-provided lead terminal is inserted into each of a pair of through-holes (111) provided at the sealing plate. The tube is deformed due to the pressure produced when inserting the lead terminal into each through-hole so as to extend in the inserting direction and thereby, it is possible to bring the tube into close contact with the round bar and with the through-holes. Therefore, it is possible to improve the airtightness of a lead-drawing portion.

摘要： Provided are an electrode formed by mixing carbon powder and a fibrous carbon, wherein influence of a resin-based binder or the like and an conductivity promoting material or the like is eliminated to have low electric resistance and an excellent property of capacitance; an electric double-layer capacitor using the electrodes; and a manufacturing method of the electrode. Provided is a dispersion step in which the carbon powder with a particle size of less than 100 nm and the fibrous carbon are dispersed into a solvent. The dispersion step is to allow jets of the solution to collide with each other or to apply shear stress and centrifugal force to the solution, thereby dispersing the carbon powder and the fibrous carbon. Furthermore, the method comprises the sheet electrode forming step in which the solution subjected to the dispersion step is filtered to obtain the carbon powder/fibrous carbon sheet.
