IPC: H01G9/035
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance reliability by adding methoxy benzenesulfonate ammonium to electrolyte composed of a solvent and a solute, thereby eliminating corrosion. SOLUTION: An electrolyte comprising 87.9 wt.% of ethylene glycol, 11.0 wt.% of ammonium sebacate, 0.1 wt.% of ammonium phosphate, and 1.0 wt.% of methoxy benzenesultonate ammonium is prepared. Corrosion is prevented when methoxy benzenesulfonate ammonium is added. It is supposed here that methoxy benzenesulfonate ammonium captures ions to prevent corrosion. A large quantity of corroded electrolytic capacitors is produced, if methoxy benzenesulfonate ammonium is not added. Corrosion also takes place when sufficient quantity of methoxy benzenesulfonate ammonium is not added.
