  • Patent number: 10014120
    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.

  • Patent number: 9548163
    Abstract: A solid electrolytic capacitor that comprises a sintered porous anode, a dielectric layer that overlies the anode body, and a solid electrolyte overlying the dielectric layer is provided. The anode is formed from a finely divided powder (e.g., nodular or angular) having a relatively high specific charge. Despite the use of such high specific charge powders, high voltages can be achieved through a combination of features relating to the formation of the anode and solid electrolyte. For example, relatively high press densities and sintering temperatures may be employed to achieve “sinter necks” between adjacent agglomerated particles that are relatively large in size, which render the dielectric layer in the vicinity of the neck less susceptible to failure at high forming voltages.

  • Patent number: 9218913
    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 contains an alkyl-substituted poly(3,4-ethylenedioxythiophene) having a certain structure. Such polymers can result in a higher degree of capacitance than many conventional types of coating materials. Further, because the polymers are generally semi-crystalline or amorphous, they can dissipate and/or absorb the heat associated with the high voltage. The degree of surface contact between the conductive coating and the surface of the metal substrate may also be enhanced in the present invention by selectively controlling the manner in which the conductive coating is formed.
