Title:
METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2022/210513
Kind Code:
A1
Abstract:
This method for manufacturing an electrolytic capacitor comprises: a first step for preparing an electrode group comprising an anode foil having a porous portion and a dielectric layer covering the surface of the porous portion, a cathode foil, and a separator disposed between the anode foil and the cathode foil; a second step for preparing a processing fluid including a conductive polymer; and a third step for, after controlling the anode foil and the processing fluid to mutually different temperatures, impregnating the electrode group with the processing fluid to form a solid electrolyte layer including the electrically conductive polymer in at least a part of the electrode group.
