Novel electrode architectures are important ingredients in designing for increased performance in energy storage devices. One approach proposes the use of carbon nanotubes and oxide nanoparticles to form a random network composed of nano-scale wires where the random network provides the high electrical conductivity needed for power delivery. Another approach describes a highly ordered array of carbon nanotubes fabricated typically on a metallic surface and used in double layer supercapacitor architectures. However neither the random network nor the ordered array of carbon nanotubes methods display performances that meet the energy storage capacity required for a large class of applications.
1) The novel geometry allows for enhanced electrochemical activity. 2) High energy storage capacity. 3) High power density.
