Document Type and Number:
WIPO Patent Application WO/2022/145451
Kind Code:
A1
Abstract:
Disclosed is an electrolytic capacitor (100) including a capacitor element (10). The capacitor element (10) includes a positive electrode, a dielectric layer formed on a surface of the positive electrode, a negative electrode, and an electrolyte layer and a separator that are arranged between the dielectric layer and the negative electrode. The electrolyte layer includes a non-aqueous solvent, electrically conductive particles, and an electrically conductive polymer. The amount of electrically conductive particles present in a dielectric-layer-side first portion of the electrolyte layer differs from the amount of electrically conductive particles present in a negative-electrode-side second portion of the electrolyte layer.
