Carbon Nanotube Foams and Nanoscale Manganese Oxide Make Improved Supercapacitor Electrodes Say Navy Scientists

Abstract:
The United States Navy (Washington, DC) garnered U.S. Patent 7,724,500 for a composite made of nanoscale manganese oxide (MnO2) on an ultraporous carbon nanoarchitecture which can be used to manufacture improved supercapacitor electrodes.

Inventors Jeffrey W. Long, Anne E. Fischer and Debra R. Rolison say the composite is a porous carbon structure with a surface and pores and a coating of MnO2 on the carbon surface, in which the coating does not completely fill or obstruct a majority of the pores. The coating is formed by self-limiting electroless deposition.
