摘要： A method for manufacturing a solid electrolytic capacitor has the steps of: mixing valve metal powders with organic binder for granulation, press-molding granulated powders embedded with a valve metal lead, sintering a press-molded compact in vacuum to produce a sintered body, and anodizing the sintered body to form a dielectric oxide film layer. The method further has a step of performing a cathode electrolytic cleaning to the sintered body before the step of forming the dielectric oxide film layer. The cathode electrolytic cleaning is performed in an acid solution, which is a mixed acid solution of hydrofluoric acid, nitric acid, and sulfuric acid.

摘要： The present invention provides a electrical double layer capacitor that can prevent the leakage of an electrolyte solution to the outside that is caused by the fractures occurring in the collectors, and thereby both the yield during manufacture processing and the reliability can be improved. Chamfered portions 20 are formed on the corners that are the border between components that are adjacent to the surfaces 12a and 12a of the polarizing electrodes 12 that do not contact a separator 11 and a collector 13, and thereby, the stress focus on these corners, which occurs easily at the contacting portions between the polarizing electrode 12 and the collector 13, occurs with difficulty.

摘要： In an electric double layer capacitor, at least three frame-shaped gaskets are stacked. A cell member of a pair of polarized electrodes sandwiching a porous separator is accommodated within a central gasket so as to be sandwiched between a pair of current collectors. Upper and lower frame shaped gaskets are adhered on both side edges of the central gasket such that the current collectors are sandwiched and held with two gaskets confronting to seal the inside of the central gasket. A step portion is formed in an inner peripheral end surface of at least one of the gaskets confronting such that each of the side edges of the collectors is received in this step portion, whereby making it easy to position the current collector in the gasket. This step portion also makes it possible to bond the current collector to the gasket at a low stress. All surfaces of the side edges of the current collectors are contacted with the gaskets to improve the reliability of the electric double layer capacitor by preventing leaking of the electrolytic solution from the capacitor cell under the high temperature environment.
