TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
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.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Principal NASA applications will include power sources for landers, rovers, deep space probes, satellites and extravehicular activities. Coupled with a suitable electrolyte and cathode, Li-ion cells based on this anode will be adaptable for space exploration-related applications, in moon and other planetary habitats, requiring high specific energy rechargeable batteries with unique attributes such as non-flammability and sub-ambient temperature operation.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The new anodes will result in high performance Li-ion batteries suitable for electric vehicle propulsion and for use in portable consumer products such as cellular phones, portable power tools, cameras and laptop computers.
