Flüssigkeitskondensatorkathode, die eine leitfähige Beschichtung enthält, welche durch anodische elektrochemische Polymerisation einer kolloidalen Suspension gebildet ist

Ein Flüssigelektrolytkondensator, der einen anodisch oxidierten porösen Anodenkörper, eine Kathode, die ein mit einer leitfähigen Beschichtung beschichtetes Metallsubstrat enthält, und einen Arbeitselektrolyten, der das Dielektrikum auf der Anode benetzt, enthält. Die leitfähige Beschichtung wird durch anodische elektrochemische Polymerisation (Elektropolymerisation) einer kolloidalen Vorläufersuspension auf der Oberfläche des Substrats gebildet.

Festelektrolytkondensator, der eine Vorbeschichtung enthält

Ein Festelektrolytkondensator, der einen Anodenkörper, welcher aus einem elektrisch leitfähigen Pulver gebildet ist, ein Dielektrikum, das sich über und/oder innerhalb des Anodenkörpers befindet, eine Haftbeschichtung, die das Dielektrikum bedeckt, und einen festen Elektrolyten, der die Haftbeschichtung bedeckt, enthält, wird bereitgestellt. Das Pulver weist eine hohe spezifische Ladung und wiederum eine relativ dichte Packungskonfiguration auf. Die Erfinder haben herausgefunden, dass das leitfähige Polymer, obwohl es aus einem solchen Pulver gebildet ist, leicht durch Imprägnieren in die Poren der Anode gebracht werden kann. Dies wird zum Teil durch die Verwendung einer diskontinuierlichen Vorbeschichtung in der Haftbeschichtung, die das Dielektrikum bedeckt, bewerkstelligt. Die Vorbeschichtung enthält eine Vielzahl von diskreten Nanovorsprüngen aus einem Manganoxid (z. B. Mangandioxid).

Festelektrolytkondensatorbaugruppe zur Verwendung bei hohen Temperaturen

Eine Kondensatorbaugruppe, die gute Eigenschaften unter heißen Bedingungen aufweisen kann. Die Fähigkeit, unter solchen Bedingungen leistungsfähig zu sein, ist zum Teil auf die Verwendung eines intrinsisch leitfähigen Polymers in dem festen Elektrolyten zurückzuführen, das Repetiereinheiten enthält, die die folgende Formel (I) aufweisen:wobei R = (CH2)a-O-(CH2)b ist; a = 0 bis 10 beträgt; b = 1 bis 18 beträgt; Z– ein Anion ist; und X+ ein Kation ist.

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.

An exemplary embodiment of the invention provides an electroconductive polymer composition having high electroconductivity which is suitable for a solid electrolytic capacitor, and provides a solid electrolytic capacitor having low ESR as well as low leakage current (LC). In an exemplary embodiment of the invention, an electroconductive polymer composition having high electroconductivity is formed by drying an electroconductive polymer suspension solution which comprises a polyanion having a cross-linked structure, an electroconductive polymer, and a solvent. In an exemplary embodiment of the invention, a solid electrolytic capacitor having low ESR as well as low LC is obtained by using the electroconductive polymer composition for a solid electrolyte layer that is an electroconductive polymer layer.

The present invention provides a solid electrolytic capacitor having a low ESR, excellent heat resistance, and reliability used under a high temperature condition. On the dielectric layer of the capacitor element, 2-alkyl-2,3-dihydro-thieno[3,4-b][1,4]dioxine monomer is subject to oxidation polymerization to provide a first conductive polymer layer.

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.
