Title:
CONDUCTIVE POLYMER DISPERSION LIQUID, ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2020/158783
Kind Code:
A1
Abstract:
A method for producing an electrolytic capacitor, which comprises: a step for preparing a fiber structure, a negative electrode foil, and a positive electrode foil that is provided with a dielectric layer; a step for preparing a conductive polymer dispersion liquid that contains a conductive polymer component and a dispersion medium; a step for forming a separator by applying the conductive polymer dispersion liquid onto the fiber structure and subsequently removing at least some of the dispersion medium therefrom; and a step for forming a capacitor element by sequentially stacking the positive electrode body, the separator and the negative electrode foil. The dispersion medium contains water. The fiber structure contains 50% by mass or more of synthetic fibers. The density of the fiber structure is 0.2 g/cm3 or more but less than 0.45 g/cm3.
