Abstract
THE PROPOSED PROGRAM RELATES TO THE EVALUATION OF A NEW CATHODE CATALYST IN DIS-TYPE LI/SOC12 CELLS. THIS NEW CA CATALYST HAS BEEN SHOWN TO CHANGE THE CATHODE REACTION MECHANISM AND TO INCREASE BOTH CATHODE RATE (FACTOR OF TEN) AND CAPACITY (FACTOR OF AT LEAST TWO) IN BOBBIN-TYPE LI/SOC12 CELLS. THE NEW MECHANISM RESULTS IN A DECREASE IN CATHODE OVERPOTENTIAL (LESS LIC1) AND A SAFER LI/SOC12 CELL.SUCCESSFUL COMPLETION OF THE PROPOSED PROGRAM WILL RESULT INPROVIDING THE MILITARY WITH A SAFE, HIGH ENERGY/POWER D DENSITY BATTERY SYSTEM CAPABLE OF MEETING THE DARPA PERF PERFORMANCE REQUIREMENTS (400W/KG), INCLUDING LOW TEM TEMPERATURE OPERATION, OF A MULTIPURPOSE HIGH-RATE POWER SOURCE. THE MAJOR OBJECTIVE OF THE PROGRAM IS TO DEMONSTRATETHAT MULTI-ELECTRODE CATALYZED-CATHODE LI/SOC12 CELLS HAVE IMPROVED PERFORMANCE; CELL COMPOMENT OPTIMIZATION WILL ALSO BE CARRIED OUT. THE PROGRAM APPROACH IS TO MAKE CATALYZED -CATHODE MULTIELECTRODE LI/SOC12 CELLS, AND TO TEST THEIR PERFORMANCE AT HIGH AND MODERATE RATE AT ROOM TEMPERATURE AS A FUNCTION OF ELECTRODE GAP, ELECTROLYTE SALT CONCERN.
