Thermally Stable High Energy Lithium-Ion Batteries for Naval Aviation Applications Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-017 Topic Title: Thermally Stable High Energy Lithium-Ion Batteries for Naval Aviation Applications Proposal No.: N081-017-1297 Firm: Yardney Technical Products, Inc. 82 Mechanic Street Pawcatuck, Connecticut 06379 Contact: Joseph Gnanaraj Phone: (860) 599-1100 Web Site: www.yardney.com Abstract: Yardney Technical Products, (YTP) proposes to develop, test and deliver high-performance Li-ion batteries capable of operation at expanded temperature range to meet the demanding requirements of naval aircraft. YTP, in collaboration with the University of Rhode Island, has been working on the development of innovative technologies that should result in durable, lightweight, Li-Ion batteries with significantly increased life performance at elevated temperatures. YTP proposes to take the innovations and concepts in this proposal (cathode type, stabilized electrolyte, binder solubility, stabilized surface coated cathodes, etc) and demonstrate that the combined enhancements will significantly improve the upper operating temperature. These improvements will also result in an ability to operate at higher voltages which, when combined with lightweight aluminum hardware, would result in significant increases in energy density and specific energy. While YTP has initially looked at some of the above areas, they have not yet been evaluated in conjunction with each other, optimized or even tested relative to the needs of naval aviation systems. YTP proposes to conduct this research as part of a Phase 1 and Phase 1 Option with the Phase 2 effort ultimately resulting in the delivery of vastly improved batteries with both traditional and iron phosphate technology. Benefits: Military Application: The target application for this expanded temperature range Li-ion battery is DOD/military, & in particular, US Navy, aircraft which must operate under demanding conditions while maximizing critical parameters such as reliability, energy density, and life-cycle. This capability could also help enable prepositioning of equipment in remote areas, such in desert locations. Non-military applications: Commercial aircraft, other weight-sensitive higher temperature applications. Return
