Title:
SOLID ELECTROLYTIC CAPACITOR ELEMENT AND SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2022/158350
Kind Code:
A1
Abstract:
This solid electrolytic capacitor element comprises: a positive electrode body; a dielectric layer formed on a surface of the positive electrode body; and a negative electrode part covering at least a portion of the dielectric layer. The negative electrode part is provided with a solid electrolyte layer covering at least a portion of the dielectric layer. The solid electrolyte layer contains a conductive polymer component containing a conjugated polymer. The solid electrolyte layer has an oxygen permeability P1, when heated at 230°C for five hours, of not more than 1.0 cm3/m2·24h·atm. Using this solid electrolytic capacitor element, it is possible to provide a solid electrolytic capacitor element and a solid electrolytic capacitor having excellent heat resistance.
