摘要： 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.

摘要： A wet electrolytic capacitor that includes a porous anode body containing a dielectric layer, an electrolyte, and a cathode containing a metal substrate that is abrasive blasted is provided. Abrasive blasting may accomplish a variety of different purposes. For example, it may result in a surface that is substantially uniform and macroscopically smooth, thereby increasing the consistency of conductive coatings formed thereon. While possessing a certain degree of smoothness, the abrasive blasted surface is nevertheless micro-roughened so that it contains a plurality of pits. The pits provide an increased surface area, thereby allowing for increased cathode capacitance for a given size and/or capacitors with a reduced size for a given capacitance. A conductive coating that contains a substituted polythiophene is disposed on the micro-roughened surface. The presence of the pits on the substrate enhances the degree of contact between the conductive coating and metal substrate, thereby resulting in improved mechanical robustness and electrical performance (e.g., reduced equivalent series resistance and leakage current).

摘要： A capacitor assembly that is stable under extreme conditions is provided. More particularly, the assembly includes a capacitor element that is positioned within an interior cavity of a housing. The housing includes a base to which the capacitor element is connected. The housing also includes a lid that contains an outer wall from which extends a sidewall. An end of the sidewall is defined by a lip extending at an angle relative to the longitudinal direction and having a peripheral edge located beyond a periphery of the sidewall. The lip is hermetically sealed to the base. In some cases, the peripheral edge of the lip is also coplanar with an edge of the base. The use of such a lip can enable a more stable connection between the components and improve the seal and mechanical stability of the capacitor assembly, thereby allowing it to better function under extreme conditions.

摘要： An electrolytic capacitor that contains an anodically oxidized anode that is incorporated with an additional metallic element is provided. More specifically, the metallic element is built into the valve metal pentoxide of the dielectric layer. In one particular embodiment, the addition of the metallic element results in a niobium pentoxide dielectric that contains closely packed units of O atoms, Nb6 octahedral, and metal atoms (“A”) that serve as counter cations. The use of relatively small electropositive metal atoms (A″) helps fill the tetrahedral (e.g., Al, Si, Ti, Mg, or Mn), octahedral (e.g., Nb, V, Mg, or Mn) and trigonal bipyramid (e.g., V, Nb) interstices of the crystals. The stability of capacitor leakage current may be improved by variation in this crystal structure.
