| titleOfInvention | Multilayer conductive polymer coatings for use in high voltage solid electrolytic capacitors |
| abstract | A solid electrolytic capacitor that can have stable electrical properties (eg, leakage current and ESR) in a variety of operating conditions is provided. The capacitor includes an oxidized anode body and a conductive polymer coating covering the anode body. The conductive polymer coating contains multiple layers formed from a dispersion of prepolymerized conductive polymer particles. The inventors have surprisingly found that unlike conventional approaches, capacitors formed from such conductive polymer coatings can operate at high voltages and achieve good electrical properties even at relatively high humidity and / or temperature levels. In particular, the inventors have found that the problem of delamination can 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 which only partially covers the anode body. Since the anode body is not completely coated, the gas bubbles produced in the first layer can more easily escape via the uncoated part without tearing away parts of the polymer layer. This minimizes the subsequent formation of surface inhomogeneities that might otherwise result in delamination. Likewise, the coating may include a second layer overlying the first layer and covering substantially the entire surface of the anode body. |
