Advanced Chemistries for Electrochemical Energy Storage Devices

This proposal is for the development of an ultrahigh energy density rechargeable lithium battery chemistry. A novel cathode material is chosen that when fully developed is expected to provide packaged batteries with specific energies of 400-500 Wh/kg. The new battery will have applications in soldier power, aircraft, high power weapons, and other military and commercial products The proposal identifies a new type of nanocomposite rechargeable lithium battery cathode material to provide high specific energy and a proprietary cell design to provide high rate capability and compact packaging. The proposal identifies the steps for preparing and identifying optimum electrode compositions, fabricating and evaluating laboratory test cells, and developing and characterizing fully packaged rechargeable lithium cells.
