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