Abstract
Provided is a new supercapacitor electrode material, comprising multiple interpenetrating networks of nanowires. More specifically, an interpenetrating network of metal oxide nanowires and an interpenetrating network of electrically conductive nanowires may form a composite film having a hierarchal porous structure. This hierarchically porous, interpenetrating network structure can provide the composite film with high capacitance, electrical conductivity and excellent rate performance. The present invention can be generalized towards other capacitor composites, opening a new avenue for a large spectrum of device applications.
