Title: ELECTROLYTIC SOLUTION FOR ALUMINUM ELECTROLYTIC CAPACITOR, AND ALUMINUM ELECTROLYTIC CAPACITOR USING SAME
Abstract:
The present invention addresses the problem of enhancing the reliability of an electrolytic capacitor so that an electrolytic solution does not leak from a sealed part even in a surrounding environment with an enhanced temperature or under humid conditions. An electrolytic solution for an aluminum electrolytic capacitor, comprising (A) an aprotic solvent, (D) an electrolyte consisting of a salt composed of (B) a cation represented by general formula (1) and (C) an anion, and (E) a compound represented by general formula (2), with the content of the compound (E) being 0.01 to 3wt% relative to the total weight of the components (A) and (D). [In general formulae (1) and (2), R1 to R3 are each C1-3 alkyl, R4 to R7 are each C1-3 alkyl or a hydrogen atom, and R8 to R14 are each C1-3 alkyl or a hydrogen atom].
