High-Efficiency High-Capacity Rechargeable Energy Storage Device Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-191 Topic Title: High-Efficiency High-Capacity Rechargeable Energy Storage Device Proposal No.: N102-191-0183 Firm: Physical Optics Corporation Information Technologies Division 20600 Gramercy Place, Bldg. 100 Torrance, California 90501-1821 Contact: Roman Ostroumov Phone: (310) 320-3088 Web Site: www.poc.com Abstract: To address the Navy JPEO JTRS need for a high-performance power energy device suitable for Military Software Defined Radio (SDR) systems, Physical Optics Corporation (POC) proposes to develop a Novel Li-ion Battery with Microstructured Silicon Anode (NOLIMITS). This innovation will yield high-energy and high-power-density Li-ion batteries with long cycling and shelf life, which cannot be equaled by other technologies. Our preliminary analysis indicates that the system can achieve gravimetric energy density exceeding 1000 Wh/kg with a wide temperature range of-40C to 55C and is the most promising solution for completely satisfying the Navy JPEO JTRS ACAT I requirements for a high performance energy storage device. In Phase I, POC will create a proof-of-concept demonstration report for a selected technology set, including recommendations for optimal approaches. POC also will evaluate the relevant parameters of NOLIMITS using modeling and small subsystems demonstration. In Phase II, POC will finalize Phase I design concept and demonstrate the technology by testing a prototype to show its potential to meet Navy JPEO JTRS needs. Benefits: The proposed technology will support a vast spectrum of commercial applications such as consumer electronics and electric vehicles, as well as DoD/NASA applications. In the consumer electronics market, the benefits of the proposed technology include cheaper, longer-lasting power sources for laptops, cell phones, and other portable personal electronic devices. For electrical vehicles, NOLIMITS technology can reduce carbon dioxide emissions and U.S. dependence on foreign oil. This technology could reduce the use of gasoline to 1/4 of today's consumption and could reduce U.S. dependence on imported oil to 1/6 of today's levels. Another use of the proposed technology is for distributed energy storage applications to effectively use intermittent renewable energy and support its delivery on demand. Return
