Title:
SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2022/163400
Kind Code:
A1
Abstract:
This solid electrolytic capacitor is provided with: a porous sintered body that constitutes a positive electrode; a dielectric layer that is formed on the porous sintered body; a solid electrolyte layer that is formed on the dielectric layer; and a conductor layer that is formed on the solid electrolyte layer so as to constitute a negative electrode. The solid electrolyte layer comprises a first layer that is formed on the dielectric layer. The first layer contains an electrolyte solution. The electrolyte solution is composed, for example, of at least one substance that is selected from the group consisting of ethylene glycol, dimethylformamide, γ-butyrolactone, a polyalkylene glycol, a polyalkylene triol, and derivatives of these compounds. Alternatively, the electrolyte solution is composed of a polymer-based electrolyte solution or a carbonate-based electrolyte solution.
