TECHNICAL ABSTRACT NEI CORPORATION PROPOSES TO DEVELOP A COMPOSITE MIXED METAL OXIDE CATHODE MATERIAL WITH A UNIQUE STRUCTURE, COMPOSITION, AND A FINE-GRAINED PARTICLE MORPHOLOGY. [LITHIUM, NICKEL, MANGANESE, COBALT]-OXIDE BASED CATHODE MATERIALS WILL BE SYNTHESIZED USING A SCALABLE AND LOW COST PROCESS DEVELOPED AT NEI. THE POWDERS WILL BE CHARACTERIZED AND EVALUATED IN BOTH HALF-CELL AND FULL LI-ION CELL CONFIGURATIONS BY WORKING IN PARTNERSHIP WITH A UNIVERSITY AND A BATTERY MANUFACTURER. THE TARGET SPECIFIC CAPACITY OF THE PROPOSED CATHODE IS 300 MAH/G WITH NOMINAL WORKING VOLTAGE OF 3.8V, WHICH GIVES OUT >1100 WH/KG SPECIFIC ENERGY. AT THE ATOMIC LEVEL, THE MATERIAL IS EXPECTED TO BE WELL ORDERED WITH AN OPEN STRUCTURE FOR FAST LI-ION INTERCALATION AND DIFFUSION (> 10-10 CM2/S). FURTHER, THE CATHODE MATERIALS DEVELOPED IN THIS PROGRAM ARE EXPECTED TO HAVE HIGH RATE CAPABILITY. HIGH STRUCTURAL STABILITY OF THE CATHODE MATERIAL WILL ENSURE THAT THE LI-ION CELL HAS HIGH CYCLE LIFE AT 100% DOD AND C/2 RATE. THE MATERIAL S CRYSTALLINE STRUCTURE WILL BE STABLE AT ELEVATED TEMPERATURES (>250OC) UPON LI-ION DEINTERCALATION, WITHOUT OXYGEN EVOLUTION. THIS WILL ALLOW THE LI-ION CELLS TO OPERATE AT HIGH ENERGY AND POWER LEVELS WITHOUT COMPROMISING ON SAFETY. IN THIS PROGRAM, NEI WILL DELIVER TO NASA TEST QUANTITIES OF CATHODE POWDERS IN YEAR 1, AND KILOGRAM QUANTITIES IN YEAR 2. THE SIX-MONTH PROGRAM IN YEAR 2 IS AN OPTION.
