March 20, 2013 – ATLANTA, GA
The Advanced Research Projects Agency-Energy (ARPA-E) awarded a project to develop high performance supercapacitors to the nGimat, Georgia Tech(lead), and Oak Ridge National Lab (ORNL) team. The ARPA-E awards are one of the most competitive high technology awards given by the US government. The team will be developing advanced supercapacitors based on graphene grafted with molecular spacers.
Current graphene based electrodes show better performance than active carbons, but the reported specific capacitances are far below the theoretical values. This is caused by limited usable surface area due to the stacking of graphene nanosheets. By adding molecular spacers to separate the nanosheets, the effective surface area will be increased.
nGimat’s role is to develop a low cost technology for large scale production of graphene based on its NanoSpraySM Combustion Processing technique, test reliability of supercapacitor coin cells made from the graphene based nanomaterial electrodes, and commercialize the developed technology.
Through its core technology of NanoSpraySM Combustion Processing, nGimat is a cost-effective manufacturer and innovator of nanoEngineered MaterialsTM in the following areas: nanopowders, thin films and devices. The Company currently has a portfolio of 46 U.S. patents, 72 non-U.S. patents, and is processing about 20 patent applications. For more information about the company, please visit www.ngimat.com.
