Abstract: A capacitor assembly that is capable of performing under extreme conditions, such as at high temperatures and/or high voltages, is provided. The ability to perform at high temperature is achieved in part by enclosing and hermetically sealing the capacitor element within a housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor element. Furthermore, the present inventors have also discovered that the ability to perform at high voltages can be achieved through a unique and controlled combination of features relating to the formation of the anode, dielectric, and solid electrolyte. For example, the solid electrolyte is formed from a combination of a conductive polymer and a hydroxy-functional nonionic polymer.

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 wet electrolytic capacitor containing a cathode, fluidic working electrolyte, and planar anode formed from an anodically oxidized sintered porous pellet is provided. The pellet may be formed from a pressed valve metal powder, which in turn, is formed by reacting an oxide of a valve metal compound (e.g., tantalum pentoxide) with a reducing agent that contains a metal having an oxidation state of 2 or more (e.g., magnesium). Through the use of such a powder, the present inventors have discovered that higher capacitance levels can be achieved than previously thought possible for the high voltage capacitors employed in implantable medical devices.
