TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Lithium-ion (Li-ion) batteries are attractive candidates for use as power sources in aerospace applications because they have high specific energy (up to 200 Wh/kg), energy density (~ 500 Wh/L) and long cycle life (1,000 – 30,000 cycles depending on the depth of cycling). Yardney/Lithion, Inc. the leader in cutting edge Li-ion batteries is dedicated in research, development, design and manufacturer of high performing battery systems for aerospace, land and sea applications. At the present moment, two of the Lithion batteries are operating on the surface of Mars with great success. Future robotic and human exploration missions require advanced human-rated energy rechargeable batteries level metrics should have specific energy of 300 Wh/kg at C/2 discharge rate and 0oC, and energy density greater than 500 Wh/l, with a calendar life of 5 years. The cycle life of the cell is required at 100% Depth of Discharge (DOD) in the range of 250 cycles. Yardney proposes to develop environmentally benign new electrode components and cell chemistries based on high capacity of 300mAh/g layered Li2MnO3 derivative cathode, composite silicon based anode with a capacity of over 600 mAh/g and suitable electrolyte.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The new composite anode and cathode based Li-ion batteries for NASA find various applications which include power for landers, rovers, and Extravehicular activities (EVA). Areas of emphasis include advanced component materials with the potential to achieve weight and volume performance improvements and safety advancements in human-rated systems.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
High capacity and high energy applications include power tools, electric vehicles and telecommunications. Automotive and industrial sectors, where the slim, small-sized battery will deliver large amounts of energy. For example, the battery's advantages in size, weight and safety highly suit it for a role as an alternative power source for hybrid electric vehicles.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
