Title:
ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/162914
Kind Code:
A1
Abstract:
An electrolytic capacitor according to the present invention comprises a capacitor element and a liquid component. The capacitor element comprises a positive electrode foil that has a dielectric layer on the surface thereof, and a conductive polymer component that is in contact with at least a part of the dielectric layer. The conductive polymer component contains a self-doped conductive polymer. The difference ∆HSP1 between the Hansen solubility parameter HSPp of the self-doped conductive polymer and the Hansen solubility parameter HSPe of the liquid component is 9.0 MPa0.5 to 11.4 MPa0.5.
