Title:
SOLID-ELECTROLYTE CAPACITOR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/185999
Kind Code:
A1
Abstract:
The present invention includes at least one solid-electrolyte capacitor element that includes: a sheet-shaped anode body having a porous section on the surface; a dielectric layer that covers at least a part of the porous section; and a cathode section that covers at least a part of the dielectric layer. The cathode section includes a solid-electrolyte layer that covers at least a part of the dielectric layer. The solid-electrolyte layer includes: a first layer that includes a first electroconductive polymer covering at least a part of the dielectric layer; and a second layer that includes a second electroconductive polymer covering at least a part of the first layer. The first layer has an inner layer filled into the voids of the porous section having the dielectric layer, and an outer layer protruding from the main surface of the porous section having the dielectric layer. A solid-electrolyte capacitor is provided that uses a solid-electrolyte capacitor having a thickness Tm of the outer layer protruding from the main surface of 1 µm or more, whereby it is possible to mitigate reduction of capacitance when repeatedly used.
