| titleOfInvention | Aluminum electrolytic capacitor |
| abstract | PROBLEM TO BE SOLVED: To easily improve electrolyte leakage under a high-temperature and high-humidity environment without using a special butyl rubber sealing material and to be present on the surface of an aluminum foil for a cathode. An object of the present invention is to provide a highly reliable aluminum electrolytic capacitor that can also improve a short circuit caused by dissolution and redeposition of copper. SOLUTION: The bulk copper content of the aluminum foil for the cathode is in the range of 0.03 to 0.35%, and the copper content on the surface of the aluminum foil for the cathode is a solution of the aluminum foil for the cathode. 45% in a 3% nitric acid aqueous solution at 45 ° C The surface of the aluminum foil for the cathode was dissolved by immersion at 3 ° C. for 3 minutes, and the amount of dissolved copper in a 3% nitric acid aqueous solution after the aluminum foil for the cathode was taken out was taken as the value measured by atomic absorption spectrometry. 0.5 μg / cm 2 or less per unit area of the aluminum foil for the cathode, and the natural potential of the aluminum foil for the cathode in the electrolytic solution is −0.50 V or more with respect to the potential of the saturated calomel electrode. It was made. |
