ELECTROLYTE FOR ELECTROLYTIC CAPACITOR AND ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte containing tetrafluoroaluminic acid ions which enables suppression of liquid leakage from a cathode and an anode of an electrolytic capacitor. SOLUTION: The electrolyte for an electrolytic capacitor contains the tetrafluoroaluminic acid ions and one or more kinds of compounds selected from a group consisting of aluminum complex, boric acid ester and silicic acid ester. An electrolytic capacitor uses the electrolyte. COPYRIGHT: (C)2007,JPO&INPIT
