SOLID ELECTROLYTIC CAPACITOR

Title:

SOLID ELECTROLYTIC CAPACITOR

Document Type and Number:

Japanese Patent JP2023068860

Kind Code:

A

Abstract:

To provide an electrolytic capacitor for suppressing the rise of an ESR even in a high temperature environment.SOLUTION: An electrolytic capacitor includes an anode foil, a cathode body, a separator, and a solid electrolyte layer. The anode foil is made of valve metal and has a dielectric oxide film formed on a foil surface. The cathode body has a cathode foil of valve metal and a carbon layer laminated on the cathode foil. The solid electrolyte layer contains a conductive polymer held in the separator and doped with an acid component. The separator contains a fiber having hydroxyl group, intermolecularly bonded by 1,4-glycosidic bond, and alkali-treated.SELECTED DRAWING: Figure 1
