ELECTROLYTIC CAPACITOR AND ELECTROLYTE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic solution for an electrolytic capacitor which electrolytic solution does not corrode or deform a sealing rubber of the electrolytic capacitor and has high conductivity and a high sparking voltage, and to provide the electrolytic capacitor which does not accompany troubles caused by a liquid leak or a gas generation to show performance stable in a long period. SOLUTION: Boron complex salt is represented by the general formula [1], where R1and R2stand for the same or different substances of hydrogen atoms, alkyl groups containing 1-4 carbon atoms, or phenyl groups; and R3, R4, R5, R6stand for the same or different substances of hydrogen atoms, or alkyl groups containing 1-4 carbon atoms. The boron complex salt and an amine as a pH regulator are dissolved into a solvent mainly composed of water to make the electrolytic solution used to fabricate the electrolytic capacitor.
