Electrolytic capacitor and method for manufacturing same
Abstract:
Disclosed is an electrolytic capacitor including: an anode body; a dielectric layer formed over the anode body; a first conductive polymeric layer covering at least one portion of the dielectric layer; a second conductive polymeric layer covering at least one portion of the first conductive polymeric layer; and an intermediate layer formed between the first conductive polymeric layer and the second conductive polymeric layer. The intermediate layer includes a cation agent containing at least one cationic group, and an anion agent containing at least one first anionic group and at least one second anionic group, and the first anionic group is higher in electron-withdrawing property than the second anionic group. The anion agent includes a polymer containing the first anionic group and the second anionic group.
