The US Navy has awarded nGimat Co. a Small Business Innovation Research (SBIR) Phase I project to develop an energy storage device that has both high energy and power density. The storage device will require a wide temperature range, long life, and exhibit minimal degradation under numerous recharge cycles.
The Naval Facilities Engineering Command (NAVFAC) uses chemical batteries as the primary technology for powering portable devices, electric vehicles, and small to large scale utility back up power supplies. Current battery technology is best suited for consumer electronics, and can’t meet the requirements for operation in harsh temperatures, maintenance free demands, and long life operation. While current Ultracapacitor technology offers these advantages, their energy densities are only 10-20% of traditional batteries. Advanced Ultracapacitor concepts are sought to provide greater energy densities than current Lithium ion batteries, require little maintenance, and operational life spans of 10 years and greater than 100,000 recharge cycles.
For the Phase I effort, nGimat will demonstrate the feasibility of high performance solid state supercapacitors based on graphene nanomaterial electrodes and solid state electrolytes in collaboration with Georgia Tech. The resulting solid state supercapacitor will eliminate leakage of liquid electrolyte and improve reliability.
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.
