  • Method for producing electrolytic capacitor
    Patent number: 10340089
    Abstract: A method for producing an electrolytic capacitor according to the present disclosure includes a first step of preparing a capacitor element that includes an anode body having a dielectric layer; a second step of impregnating the capacitor element with a first treatment solution containing at least a conductive polymer and a first solvent; and a third step of impregnating, after the second step, the capacitor element, in which at least a part of the first solvent remains, with a second treatment solution containing a coagulant to coagulate the conductive polymer.
    Type: Grant
    Filed: December 14, 2016
    Date of Patent: July 2, 2019
