Title:
SOLID ELECTROLYTIC CAPACITOR, AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/070604
Kind Code:
A1
Abstract:
Provided are: a manufacturing method for increasing a capacity appearance rate of a solid electrolytic capacitor; and a solid electrolytic capacitor with an increased capacity appearance rate. A wound body 1, in which a positive electrode foil and a negative electrode foil, on which dielectric films are formed, are wound facing each other, is securely wrapped with a hydrophobic adhesive tape 2. A conductive polymer is formed using a conductive polymer liquid in which the conductive polymer is dispersed or dissolved and which has a viscosity of 10 mPa·s to 60 mPa·s. That is, the conductive polymer is attached to the inside of the wound body 1 by immersing the wound body 1 securely wrapped with the adhesive tape 2 in a conductive polymer liquid having a viscosity of 10 mPa·s to 60 mPa·s.
