アルミニウム電解コンデンサ用電解液、及びそれを用いたアルミニウム電解コンデンサ
Document Type and Number:
Japanese Patent JP7112837
Kind Code:
B2
Abstract:
To provide an electrolytic solution for an aluminum electrolytic capacitor, which is superior in the effect of enhancement of voltage resistance to a conventional electrolyte solution in which polyvinyl alcohol is used as a voltage resistance-increasing agent.SOLUTION: The above problem is solved by an electrolytic solution for an aluminum electrolytic capacitor. The electrolytic solution comprises polyoxyalkylene polyglyceryl ether in which ethylene oxide and propylene oxide are added by a total of 20 to 100 moles to polyglycerin having an average degree of polymerization of 2 to 10, and the proportions thereof is EO:PO=61:39 to 80:20.SELECTED DRAWING: None
