Research Institution
This proposal addresses the Army"s need for rechargeable 18650-type lithium-ion cells with specific energy greater than 300 Wh/kg for Land Warrior applications. The proposed cells will allow a Soldier to drastically extend the mission run time and reduce the frequency of changing the batteries. The improvements in specific energy will be achieved by radical enhancements of the cell"s chemistry and introduction of the next generation, high energy active materials in both cathode and anode. Cell safety improvements will also be implemented as a part of this effort. In this project, high capacity/energy cathode based on lithium nickel cobalt manganese oxide active material, capable of delivering ~250 mAh/g during C/10 discharge, with an average discharge potential of 3.55 V will be set against the high capacity, nano-engineered anode, based on silicon-carbon active material, capable of delivering>1000 mAh/g, and both electrodes will be implemented into 18650-type lithium-ion cells.
