Abstract: A method of manufacturing an aluminum electrolytic capacitor includes impregnating an aluminum electrolytic capacitor with a first electrolyte to form a first impregnated capacitor, aging the first impregnated capacitor using a first aging process to form a first aged capacitor, impregnating the first aged capacitor with a second electrolyte to form a second impregnated capacitor, the second electrolyte being different from the first electrolyte, aging the second impregnated capacitor using a final aging process to form a final aged capacitor, and impregnating the final aged capacitor with a third electrolyte.

Abstract: Electrolytic capacitors, and methods and apparatus for making the same are disclosed in herein. In one embodiment, a cathode comprises a conductive sheet having a central portion defined by a peripheral edge, a first tail extending out from the peripheral edge in a first direction, and a second tail extending out from the peripheral edge in a second direction opposite the first direction, wherein each of the first tail and the second tail has a first recess at a free end thereof.
