US Patent 7852612 Supercapacitor using carbon nanosheets as electrode

A supercapacitor comprises a first electrode, a second electrode, and a separator. The electrodes are created with carbon nanosheets in various configurations. For example, the carbon nanosheets may be disposed orthogonal to a surface to which it is attached and comprise a single graphene layer or multiple graphene layers. The electrodes are impregnated with an electrolyte.
