A wet electrolytic capacitor that includes a porous anode body containing a dielectric layer, a cathode containing a metal substrate on which is disposed a conductive polymer coating, and an electrolyte is provided. The conductive polymer coating is in the form of a dispersion of particles having a relatively small size, such as an average diameter of from about 1 to about 500 nanometers, in some embodiments from about 5 to about 400 nanometers, and in some embodiments, from about 10 to about 300 nanometers. The relatively small size of the particles used in the coating increases the surface area that is available for adhering to the metal substrate, which in turn improves mechanical robustness and electrical performance (e.g., reduced equivalent series resistance and leakage current). Another benefit of employing such a dispersion for the conductive polymer coating is that it may be able to better cover crevices of the metal substrate and improve electrical contact.

In addition, because the uniform polymer film is formed irrespective of the size of metal pores and the shape of the capacitor, a capacity of the capacitor can be maximized.

Multi-Layered Conductive Polymer Coatings for Use in High Voltage solid Electrolytic Capacitors

A solid electrolytic capacitor that is capable of exhibiting stable electrical properties (e.g., leakage current and ESR) in a wide variety of operational conditions is provided. The capacitor contains an oxidized anode body and a conductive polymer coating overlying the anode body. The conductive polymer coating contains multiple layers formed from a dispersion of pre-polymerized conductive polymer particles. Unlike conventional attempts, the present inventors have surprisingly discovered that capacitors formed from such conductive polymer dispersions can operate at high voltages, and also achieve good electrical performance at relatively high humidity and/or temperature levels. More particularly, the present inventors have discovered that the problem of layer delamination may be overcome by carefully controlling the configuration of the conductive polymer coating and the manner in which it is formed. Namely, the coating contains a first layer that only partially covers the anode body. Because the anode body is not completely coated, the gaseous bubbles generated within the first layer are able to more easily escape via the uncoated portion without tearing away portions of the polymer layer. This minimizes the subsequent formation of surface inhomogeneities that could otherwise lead to delamination. The coating may likewise contain a second layer that overlies the first layer, and covers substantially the entire surface of the anode body.
