ENGI-MAT CO — Department of Defense STTR Phase I: nGimat & Oak Ridge National Labs jointly propose to develop safe high-voltage cathode

Description

nGimat & Oak Ridge National Labs jointly propose to develop safe high-voltage cathode materials for pulsed power applications in the military and commercial sectors. nGimat's versatile NanoSpray Combustion process will be utilized to tailor the bulk & surface composition of the cathode materials as well as the particle size & morphology to meet the demanding energy, power and safety requirements of emerging battery applications. During the Phase I effort, nGimat will develop structurally stable, surface coated, sub-micron-sized high-voltage battery cathode materials that will have optimized energy-density, power-density and thermal-stability. The electrochemical performance of the cathode materials will be demonstrated in small lab-scale electrochemical cells. Calorimetric analysis will also be performed to determine the thermal stability of the cells. In Phase II, we will partner with a leading battery manufacturing R & D center to develop large commercial-scale cells and modules to validate capacity, cycle life and thermal stability under various conditions. In addition collaborations will be forged with a leading developer of high-voltage electrolytes to ensure success in the program. In the long run, by using low-cost, environmentally-friendly precursors we will develop an inherently scalable & energy-efficient process that will allow cost-effective production of high-performance battery materials.
