Electrolyte for electrolytic capacitor

摘要

An electrolyte for electrolytic capacitor containing within an aprotic solvent a fluorocomplex acid salt of aniline or aniline derivative as solute. An electrolyte for electrolytic capacitor according to the invention may conveniently be prepared by adding one equivalent amount of aniline or aniline derivative to an aqueous solution of fluorocomplex acid for reaction with subsequent vacuum drying to obtain an anhydrous salt and then dissolving said anhydrous salt to an aprotic solvent until a desired conductivity is obtained, for example, as an approximately 10% by weight solution.
