Thermally Stable High Energy Lithium-Ion Batteries for Naval Aviation Applications

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.
