Abstract

An electrolyte for use in an aluminum electrolytic capacitor is described. The electrolyte comprises a solution of a quaternary phosphonium salt as a solute dissolved in an aprotic solvent. The electrolyte can reduce internal resistance of the electrolytic capacitor and broaden the temperature range over which the electrolytic capacitor can be used.
