Abstract: A capacitor for use in ultrahigh voltage environments is provided. During formation of the capacitor, the forming voltage employed during anodization is generally about 300 volts or more and at temperatures ranging from about 10° C. to about 70° C. Such conditions can substantially improve the quality and thickness of the dielectric without adversely impacting the uniformity and consistency of its surface coverage. In addition, the solid electrolyte is also formed from a dispersion of preformed conductive polymer particles. In this manner, the electrolyte may remain generally free of high energy radicals (e.g., Fe2+ or Fe3+ ions) that can lead to dielectric degradation, particularly at the ultrahigh voltages noted above.

Abstract: A wet electrolytic capacitor that includes a sintered porous anode body containing a dielectric layer, a fluid electrolyte, and a cathode is provided. At least one longitudinally extending channel is recessed into the anode body. The channel may have a relatively high aspect ratio (length divided by width), such as about 2 or more, in some embodiments about 5 or more, in some embodiments from about 10 to about 200, in some embodiments from about 15 to about 150, in some embodiments from about 20 to about 100, and in some embodiments, from about 30 to about 60.
