    摘要： An electrolyte having a high conductivity, an excellent high-temperature life characteristic and leading to improvement of the shelf characteristic of an aluminum electrolytic capacitor. At least one phosphate ion producing compound and a chelating agent are added using a solvent largely composed of water. Therefor, an aluminum electrolytic capacitor comprising such an electrolyte has a low impedance, an excellent high-temperature life characteristic, and an improved shelf characteristic.

    摘要： An electrical double-layer capacitor electrode with excellent capacitance characteristics is obtained together with a manufacturing method therefor.Paper-molded sheet 2 of carbon nanotubes is integrated with etched foil 1 constituting a collector, by means of bumps and indentations 1a formed on the surface of etched foil 1 to prepare an electrical double-layer capacitor electrode. Alternatively, carbon nanotubes 4 grown around core catalyst particles on substrate 3 are integrated with etched foil 1 by means of bumps and indentations 1a formed on the surface of etched foil 1 to prepare an electrical double-layer capacitor electrode. To manufacture these electrodes, this carbon nanotube sheet 2 or substrate 3 with carbon nanotubes grown thereon is laid over bumps and indentations la on the surface of etched foil 1, and the sheet or substrate and the foil are pressed under 0.01 to 100 t/cm2 of pressure to integrate the carbon nanotubes with the etched foil.

    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.
