An electrolytic solution, for use in an electrolytic capacitor, comprising a solvent and a solute wherein water accounts for 20 to 100% by weight of the solvent and the total solute content is from 1.5 to 44% by weight, and an electrolytic capacitor comprising a capacitor element, a case containing the capacitor element, and a sealant with which the case is sealed, the capacitor element comprising a pair of electrode foils each comprising a dielectric, a separator for isolating the electrode foils from each other, and the above electrolytic solution filled between the electrode foils.
摘要:
An electrolytic capacitor using an electrolytic solution constituted by a solvent consisting of from 20 to 80 wt % of an organic solvent and from 80 to 20 wt % of water, the electrolytic capacitor comprising a nitro or nitroso compound except for nitrophenol, nitrobenzoic acid, dinitrobenzoic acid, nitrophenone and nitroanisole, in a portion inside the capacitor other than in the electrolytic solution. The electrolytic capacitor exhibits a low impedance, excellent low temperature stability and good life characteristics, and further, is excellent in the effect to absorb a hydrogen gas, even when use is made of an electrolyte solution employing mixed solvent having a great water content and when an electrolytic capacitor is used under a high temperature condition.
