NASA 1999 SBIR Phase I


PROPOSAL NUMBER: 99-1 17.01-1140 (Chron: 990429)

PROJECT TITLE: Chemically Stable 5V Cathode Materials for Lithium and Lithium-ion Batteries

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Lithium-ion batteries, successfully commercialized by the Japanese, have found an important niche in powering consumer electronics products such as laptop computers and cellular phones. Nonetheless, lithium and lithium-ion batteries with both higher voltage and higher specific energies are required for 21st Century applications by NASA and our domestic aerospace industry. Preliminary work at Covalent has demonstrated that 5V cathode materials with enhanced safety characteristics and improved energy densities may be synthesized by a simple route which is amenable to industrial scale-up. In Phase I we will synthesize, characterize and demonstrate both cycle life and high specific capacities of these novel materials.



POTENTIAL COMMERCIAL APPLICATIONS

Stable, high voltage transition metal oxide cathode materials with theoretical specific energies in excess of 1200 Wh/kg are the key to advanced lithium and Li-ion batteries for both military and commercial applications. Such batteries will be employed in portable computers, hand held communication devices, satellites and electric vehicles.
