VOLTAGE RESISTANCE IMPROVER OF ELECTROLYTE FOR DRIVING ELECTROLYTIC CAPACITOR, AND ELECTROLYTE FOR DRIVING ELECTROLYTIC CAPACITOR CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a voltage resistance improver of an electrolyte for driving an electrolytic capacitor and the electrolyte for driving an electrolytic capacitor containing the same.SOLUTION: For polyglycerol whose glycerin concentration is 10 wt% or less, whose diglycerol concentration is 20 wt% or less, and whose average polymerization degree calculated from a hydroxyl value is from 3 to 20, polyoxyethylene polyglyceryl ether formed by addition of an ethylene oxide is used as an additive agent of an electrolyte for driving an electrolytic capacitor.
