Title:
ELECTROLYTIC CAPACITOR AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/200775
Kind Code:
A1
Abstract:
A production method for an electrolytic capacitor that contains a positive electrode body in the form of a foil having a dielectric layer on the surface thereof, and a negative electrode body in the form of a foil, said production method comprising: a step (i) in which a separator and the positive electrode body and the negative electrode body, which are disposed facing each other with the separator therebetween, are wound or layered to form a capacitor element precursor; a step (ii) in which a treatment solution containing an acid component, a solvent, and a conductive polymer component is impregnated into the capacitor element precursor; a step (iii) in which a liquid component is impregnated into the capacitor element precursor that has undergone step (ii); and a step (iv) in which the acid component is eluted into the liquid component to obtain a capacitor element.
