Title:
METHOD FOR PRODUCING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/120707
Kind Code:
A1
Abstract:
Disclosed is a production method which comprises: a multilayer body formation step in which a multilayer body (100) is formed by stacking a positive electrode foil, a negative electrode foil and a separator (130) such that the separator (130) is arranged between the positive electrode foil and the negative electrode foil; and a polymer layer formation step in which a conductive polymer layer that contains a conductive polymer is formed in the multilayer body (100) by impregnating the multilayer body (100) with a dispersion liquid that contains the conductive polymer and a dispersion medium, and subsequently evaporating at least some of the dispersion medium of the dispersion liquid in the multilayer body (100). The multilayer body formation step additionally comprises a process in which the outer periphery of the multilayer body (100) is surrounded by a bundling member (150). The separator (130) has a projection part (130b) that protrudes from the bundling member (150). In the polymer layer formation step, the multilayer body (100) is impregnated with the dispersion liquid through the projection part (130b).
