In the Phase-I project Avomeen LLC will advance the manufacturing technology that has already developed thermally stable separators in-house. In Phase I project, Avomeen will develop thermally stable separator and related low cost manufacturing process to achieve high energy/power density lithium ion batteries with enhanced safety. Currently micro-porous material and glass material are using as a separator to provide electrical isolation for the electrodes in lithium ion batteries. The proposed separators will be maximizing volumetric efficiency for electrolyte capacity. The proposed separators are chemically compatible with electrolyte and reaction products after activation. Electrolyte wettability, heat resistance and oxidation resistance will be improved by using coatings made of materials that exhibit high affinity with liquid electrolytes. This better wettability, heat resistance and oxidation resistance contributes to longer battery life, enhance the battery safety and allows higher voltages and higher energy/power densities. On a follow on Phase-II project this technology will be commercialized by a leading lithium ion battery manufacturer who is very much interested in this technology.
Benefit: Successful development of the proposed electrodes, separators and electrolytes for Achieving High Energy/Power Density, Safe, and Long Lasting Lithium-ion Batteries for Navy Aircraft Applications would lead to commercialization of the materials through fabrication of new batteries for Navy and through licensing opportunities to other battery companies and chemical manufacturers. Safe lithium ion batteries are needed for the aerospace market and as lithium ion batteries are increased in size for electric vehicle applications, safety is of paramount importance. Nonflammable electrolytes and stable separators are needed to penetrate these new markets and will represent a lucrative commercial opportunity when developed. BIC, Solar Turbines, Lockheed Martin and General Electric expressed interest in supporting and participating in our Phase I study.
