Abstract: A capacitor assembly that is capable of exhibiting good properties under humid conditions. The ability to perform under such conditions is due in part to the use of an intrinsically conductive polymer in the solid electrolyte that contains repeating units having the following formula (I): wherein, R is (CH2)a—O—(CH2)b; a is from 0 to 10; b is from 1 to 18; Z is an anion; and X is a cation. Due to its unique structure, the polymer is not highly sensitive to moisture. Consequently, the resulting capacitor assembly may exhibit excellent electrical properties even when exposed to high humidity levels.

The casing contains a conductive coating disposed on a surface of a metal substrate. The casing contains a metal substrate coated with a conductive coating.

Abstract: A wet electrolytic capacitor that contains a casing within which is positioned an anode formed from an anodically oxidized sintered porous body and a fluidic working electrolyte is provided. The casing contains a metal substrate over which is disposed a hydrogen protection layer that contains a plurality of sintered agglomerates formed from a valve metal composition. The present inventors have discovered that through careful selection of the relative particle size and distribution of the agglomerates, the resulting protection layer can effectively absorb and dissipate hydrogen radicals generated during use and/or production of the capacitor, which could otherwise lead to embrittlement and cracking of the metal substrate.

Abstract: A capacitor assembly for use in high voltage and high temperature environments is provided. More particularly, the capacitor assembly includes a capacitor element containing an anodically oxidized porous, sintered body that is coated with a manganese oxide solid electrolyte. To help facilitate the use of the capacitor assembly in high voltage (e.g., above about 35 volts) and high temperature (e.g., above about 175° C.) applications, the capacitor element is enclosed and hermetically sealed within a housing in the presence of a gaseous atmosphere that contains an inert gas. It is believed that the housing and inert gas atmosphere are capable of limiting the amount of moisture supplied to the manganese dioxide. In this manner, the solid electrolyte is less likely to undergo an adverse reaction under extreme conditions, thus increasing the thermal stability of the capacitor assembly. In addition to functioning well in both high voltage and high temperature environments, the capacitor assembly of the present invention may also exhibit a high volumetric efficiency.

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.
