    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 conductive coating disposed on a surface of a metal substrate. The casing contains a metal substrate coated with a conductive coating. The conductive coating contains a conductive polymer layer formed through anodic electrochemical polymerization (“electro-polymerization”) of a colloidal suspension on the surface of the metal substrate. The conductive coating also contains a precoat layer that is discontinuous in nature and contains a plurality of discrete projections of a conductive material that are deposited over the surface of the metal substrate in a spaced-apart fashion so that they form “island-like” structures.

    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.
