Abstract
THE OBJECTIVE OF THE PROPOSED WORK IS THE DEVELOPMENT OF A AA LITHIUM/TITANIUM DISULFIDE RECHARGEABLE CELL WITH AN ENERGY DENSITY ABOVE 100 WH/KG AND WITH A CYCLE LIFE OF 1000DISCHARGE CHARGE CYCLES. THE PROPOSED WORK WILL FOCUS ON THE DESIGN, ASSEMBLY, AND TESTING OF AA CELLS IN PRACTICAL HARDWARE. EXPERIMENTAL DESIGN TECHNIQUES WILL BE USED TO INVESTIGATE MODIFICATIONS OF ANODE, CATHODE, AND ELECTROLYTE. DATA ANALYSIS OF THE RESULTS OF THE DESIGNED EXPERIMENT WILL ALLOW DETERMINATION OF THE VARIABLE HAVING THE GREATEST IMPACT ON CYCLE LIFE AND ANY INTERACTION OCCURRING BETWEEN VARIABLES. THIS ANALYSIS WILL ALLOW FOCUS OF PHASE II EFFORTS ON THE AREA IN GREATESTNEED OF IMPROVEMENT IN ORDER TO ALLOW DEVELOPMENT OF A CELL WITH THE DESIRED PERFORMANCE SPECIFICATIONS.
