Abstract
Disclosed are a hybrid aluminum electrolytic capacitor and a method of producing the same. The preparation method includes impregnating a capacitive element in a fluid to improve the low-temperature property, where the fluid is prepared from a first organic solvent having a boiling point of 180° C. or more and a melting point of −50° C. or less, a small number of an inorganic or organic acid and an amine having a boiling point of 180° C. or more.
