Title:
SOLID ELECTROLYTIC CAPACITOR AND PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/058267
Kind Code:
A1
Abstract:
Provided is a solid electrolytic capacitor that has low ESR even with a conductive layer formed on a negative electrode foil. A solid electrolytic capacitor according to the present invention comprises: a positive electrode body that has a dielectric coating film; a negative electrode body; and an electrolyte layer that is interposed between the positive electrode body and the negative electrode body. The negative electrode body includes: a negative electrode foil that comprises a valve metal; and a conductive layer that is formed on the negative electrode foil. The electrolyte layer includes a conductive polymer and contacts at least the conductive layer. The negative electrode foil has a foil capacity of at least 20 μF/cm2.
