Abstract
A new high capacity rechargeable Li battery anode based on Li metal alloys protected by carbon nanoshells will be developed. A reversible Li-ion capacity exceeding 600 mAh/g or nearly twice that obtainable with graphite anodes is expected. Coupled with our advanced polymer electrolyte and high voltage cathode, we expect a fully developed battery to have a specific energy of >150 Wh/Kg, and energy density of >300 Wh/l and the capability to produce >1000 deep charge/discharge cycles and thus makes it very desirable for space power applications of NASA.
