NOVELTY - The utility model claims a foamed thin film capacitor, comprising a porous foam skeleton, the porous foam skeleton is a foam metal foil, foam metal foil outer surface provided with at least one layer of composite capacitor layer, a composite capacitance layer is orderly provided with a graphene layer, a dielectric layer and a conductive layer, the graphene layer and the conductive layer as two electrodes of the foamed thin film capacitor. the foamed thin film capacitor made of foam metal foil as the capacitor core graphene layer, a dielectric layer and a conductive layer of the carrier, the foam metal foil having a large surface area, and thickness can be very thin. so as to greatly reduce the thickness of the capacitor core material, at the same time, because the graphene material has exceptionally high conductivity and large surface area and so on, this utility model capacitor energy storage and release than the similar product in the process of further has advantages of high.
