ELECTROLYTE FOR USE IN A CAPACITOR

摘要

PROBLEM TO BE SOLVED: To obtain electrolyte having high conductivity and a high breakdown voltage in an electrolytic capacitor. SOLUTION: This electrolyte is an electrolyte for activating an electrolytic or electrochemical capacitor. The electrolyte preferably includes a mixed solvent of water and ethylene glycol having an ammonium salt dissolved therein. An acid such as phosphoric or acetic acid is used to provide a pH of about 3 to 6. The electrolyte is particularly useful for activating a ruthenium oxide/ tantalum capacitor having an anode breakdown voltage in the range of 175 to 300 volts.
