TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Current state-of-the-art Lithium (Li) or Li-ion systems are unable to meet the performance goals of space-rated rechargeable batteries for many NASA's future robotic and human exploration missions. They either cannot provide sufficient energy and power or have poor cycle or calendar life. TH Chem, Inc. (THC) proposes to develop a new electrochemical system that is fundamentally different from the state-of-the-art, for advanced Li battery applications. Li batteries developed from the new system will show significantly improved battery performance characteristics including energy/power density, cycle/calendar life, cost, and abuse tolerance. The new system is based on development of novel polymeric cathode materials (PCMs) having high-energy functional groups chemically grafted to a robust polymer backbone. In Phase I, THC will prepare the proposed PCMs by functionalization of an inexpensive polymeric starting material. Li cells will be assembled using the PCMs and electrochemically evaluated. The concept of the new electrochemical system will be demonstrated. THC has extensive experience in Li battery chemistries and technologies.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
High performance Li-based batteries will provide more stored energy and power for NASA's power systems in robotic and human exploration missions, satellites, spacecraft, and probes.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Lithium batteries have extensive applications in commercial products including electric vehicles, cellular telephones, lap-top computers, digital cameras, tools, and other consumer products.

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.
