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.: N081-017-0246 Firm: Concorde Battery Corporation 2009 San Bernardino Road West Covina, California 91790 Contact: David Vutetakis Phone: (336) 884-5370 Web Site: www.concordebattery.com Abstract: The objective of the proposed work is to develop thermally stable lithium-ion cells capable of withstanding the full operating temperature range of Navy aircraft. The primary technical goal is to enhancing the thermal stability of electrolytes and electrolyte/electrode interfaces to allow long operating life when exposed to a wide temperature range. In Phase I, the feasibility of alternative electrolyte formulations will be demonstrated using full-size cells. In Phase II, a prototype battery system will be developed for test and evaluation purposes. Cost feasibility will also be included by estimating the cost to manufacture batteries that are form, fit and function replacements for Navy aircraft. Benefits: The demand for more power and lower weight is growing in both the military and commercial aircraft industry. A lithium-ion battery will provide the user with a lightweight, high power alternative when compared to alternative technologies such as lead-acid and nickel-cadmium batteries. A weight reduction of at least 50% is anticipated, including the necessary electronic protection circuits. By extending the operating temperature range, the longevity of the lithium-ion battery will surpass that of competing technologies, making the life cycle cost very attractive. The present SBIR topic area represents an important stepping-stone on the path toward commercialization. This topic provides an opportunity to develop lithium-ion batteries that are form, fit and function replacements for existing lead-acid and nickel-cadmium batteries. Return
