Abstract: A wet electrolytic capacitor that includes a porous anode body containing a dielectric layer, an electrolyte, and a cathode containing a metal substrate on which is disposed a conductive coating is provided. Prior to application of the conductive coating, the metal substrate is blasted with abrasive particles to enhance the ability of the substrate to adhere to the coating. The micro-roughened metal substrate can be treated after blasting so that substantially all of the abrasive particles are removed. This is accomplished by contacting the metal substrate with an extraction solution to remove the particles, and also by selectively controlling the nature of the abrasive particles so that they are dispersible (e.g., soluble) in the solution.

Abstract: A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body is provided. The powder may have a high specific charge and in turn a relative dense packing configuration. Despite being formed from such a powder, a manganese precursor solution can be readily impregnated into the pores of the anode. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner.
Abstract translation: 提供了一种固体电解电容器，其包含由导电粉末形成的阳极体和位于阳极体上方和/或内部的电介质涂层。 粉末可以具有高比电荷，反过来又具有相对密集的封装结构。 尽管由这种粉末形成，但锰前体溶液可以容易地浸渍到阳极的孔中。 这部分地通过在前体溶液中使用分散剂来实现，其有助于最小化当接触电介质表面时氧化锰前体将形成液滴的可能性。 相反，前体溶液可以更好地分散，使得所得到的氧化锰具有“膜状”构型，并以基本上均匀的方式涂覆阳极的至少一部分。

Abstract: A wet electrolytic capacitor that contains an anodically oxidized porous anode body, a cathode containing a metal substrate coated with a conductive coating, and a working electrolyte that wets the dielectric on the anode. The conductive coating is formed through anodic electrochemical polymerization (“electro-polymerization”) of a precursor colloidal suspension on the surface of the substrate. The colloidal suspension includes a precursor monomer, ionic surfactant, and sulfonic acid, which when employed in combination can synergistically improve the degree of surface coverage and overall conductivity of the coating.
