Abstract:
Ultracapacitor electrodes having an enhanced electrolyte-accessible surface area are provided. Such electrodes can include a porous substrate having a solution side and a collector side, the collector side operable to couple to a current collector and the solution side positioned to interact with an electrolytic solution when in use. The electrode can also include a conductive coating formed on the solution side of the porous substrate. The coating can have a first side positioned to interact with an electrolytic solution when in use and a second side opposite the first side. The coating can have discontinuous regions that allow access of an electrolyte solution to the second side during use to enhance electrolyte-accessible surface area of the conductive coating.

Abstract:
In one embodiment, a structure for an energy storage device may include a first nanostructured substrate having a conductive layer and a dielectric layer formed on the conductive layer. A second nanostructured substrate includes another conductive layer. A separator separates the first and second nanostructured substrates and allows ions of an electrolyte to pass through the separator. The structure may be a nanostructured electrolytic capacitor with the first nanostructured substrate forming a positive electrode and the second nanostructured substrate forming a negative electrode of the capacitor.
