Title:
METHOD FOR PRODUCING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/120309
Kind Code:
A1
Abstract:
A method for producing an electrolytic capacitor according to the present invention comprises a step for forming a solid electrolyte layer, which contains a conductive polymer, on the surface of a positive electrode body that is provided with a dielectric layer. The step for forming a solid electrolyte layer comprises: a first step in which a first conductive polymer layer that covers the dielectric layer is formed by having the positive electrode body impregnated with a first solution, which contains a first monomer that serves as the starting material for a first conductive polymer, and polymerizing the first monomer on the surface of the dielectric layer; and a second step in which a second conductive polymer layer that covers the first conductive polymer layer is formed by having the positive electrode body impregnated with a second solution or a second dispersion liquid, each of which contains the second conductive polymer. The second step comprises low-pressure processing of the positive electrode body.
