The energy-storing cableΓÇÖs formation begins with a core conductor wire, on the surface of which nanowhiskers of insulating copper oxide are grown, perpendicular to the wire. The 100-fold increase in surface area enables a higher level of capacitative energy storage. These nanowhiskers are then coated with an alloy of gold and palladium to form the supercapacitorΓÇÖs current collector, followed by an electrochemically active coating of manganese oxide. The first layer is then complete and separated from a second layer of the same composition as the first by a solid electrolyte and porous polymer. Increased surface area from the two layers, each featuring many nanowhiskers, enables high energy storage around the conventional copper coaxial wire for energy transmission.
