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.
