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 method of producing interlayer distance controlled graphene, an interlayer distance controlled graphene composition, and a supercapacitor are provided.
