Abstract: A solid electrolytic capacitor and method for making the capacitor are provided. The capacitor includes a porous anode body, an anode foil, a dielectric, a cathode, and anode and cathode terminations. The foil is disposed on a planar surface of the anode body, and both comprise a valve metal. Further, the dielectric overlies at least a portion of the anode body, and the dielectric is also formed within the anode body. The cathode overlies at least a portion of the dielectric that overlies the anode body and includes a solid electrolyte, where at least a portion of a lower surface of the foil is free of both the dielectric and the solid electrolyte. In addition, the anode termination is electrically connected to the portion of the lower surface of the foil that is free of both the dielectric and the solid electrolyte, and the cathode termination is electrically connected to the solid electrolyte.

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.

Abstract: A supercapacitor module is provided. In some implementations, the supercapacitor module may include a first supercapacitor having a first parameter value for a capacitor parameter in a first test condition. The supercapacitor module may include a second supercapacitor having a second parameter value for the capacitor parameter in about the first test condition. A ratio of the second parameter value to the first parameter value may be from about 0.8 to about 1.2. The supercapacitor module may prevent overvoltages across the first and second supercapacitors, such that the supercapacitor module may satisfactorily operate without a balancing circuit.

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.
