Abstract
In one aspect of the present invention, an ultracapacitor has a first plate, a second plate and a separator sandwiched between the first plate and the second plate. Each of the first plate and the second plate includes a substrate, first nanostructures formed on the substrate, and second nanostructures, being different from the first nanostructures, attached to the first nanostructures. The first nanostructures include carbon nanotubes (CNTs) or carbon fibers/nanofibers (CFs). The second nanostructures include nano-particles of an active material including MnO2.
