Novel Separator Materials for Achieving High Energy/Power Density, Safe, Long-Lasting Lithium-ion Batteries for Navy Aircraft Applications.

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.
