Title:
SOLID ELECTROLYTIC CAPACITOR ELEMENT AND SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2022/024771
Kind Code:
A1
Abstract:
The present invention is provided with: an anode body; a dielectric layer formed on a surface of the anode body; and a cathode part covering at least a portion of the dielectric layer. The cathode part is provided with a solid electrolyte layer covering at least a portion of the dielectric layer. The solid electrolyte layer contains: a first polymer component including a monomer unit that corresponds to a thiophene compound; and a second polymer component including a polymer anion. The initial ESR of the solid electrolytic capacitor can be kept low by using a solid electrolytic capacitor element in which a peak specific to the first polymer component is observed in a Raman spectrum in an outer layer of the solid electrolyte layer.
