Title:
SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/070603
Kind Code:
A1
Abstract:
The present invention provides: a production method which enhances the capacitance appearance ratio of a solid electrolytic capacitor; and a solid electrolytic capacitor which has an enhanced capacitance appearance ratio. According to the present invention, winding of a wound body 1 which is obtained by winding a negative electrode foil and a positive electrode foil that is provided with a dielectric oxide coating film, the negative electrode foil and the positive electrode foil facing each other, is stopped by means of a hydrophobic adhesive tape 2. A lead terminal 3, wherein a flat part 33, a round bar part 32 and a lead-out line 31 are linked in series, is connected to the positive electrode foil and the negative electrode foil at the flat part 33. The wound body 1 is immersed in a conductive polymer liquid to at least a half of the height of the round bar part 32 of the lead terminal 3, or to 1 mm or more from one end face 1a of the wound body 1; and a conductive polymer is adhered to at least a half of the height of the round bar part 32, or to 1 mm or more from the end face 1a of the wound body 1 in addition to the inside of the wound body 1.
