ABSTRACT:
An electrolyte for electrolytic capacitor containing within an aprotic solvent a fluorocomplex acid salt of a N-heterocyclic compound as solute.
An electrolyte for electrolytic capacitor according to the invention may conveniently be prepared by adding to an aqueous solution of fluorocomplex acid salt an equivalent amount of N-heterocyclic compound for reaction with subsequent dryness at reduced pressure to obtain an anhydrous salt which is then added to the aprotic solvent to prepare the resultant electrolyte having desired conductivity.
