Abstract
A RESEARCH PROGRAM TO IDENTIFY AND IMPROVE THE PARAMETERS WHICH AFFECT THE PERFORMANCE OF THE LI/POLYMER ELECTROLYTE/LIMN204 CELL IS PROPOSED. THE CELL, USING THE HIGHLY REVERSIBLE LIMN204 INSERTION CATHODE, WILL UTILIZE A POLYACRYLONITRILE BASED POLYMER ELECTROLYTE WITH A CONDUCTIVITY OF >10-3 OHM-1CM-1 AT ROOM TEMPERATURE. A MAJOR EMPHASIS WILL BE PLACED ON DETERMINING THE OPTIMUM COMPOSITION OF THE COMPOSITE CATHODE COMPRISING LIMN204, CARBON AND POLYMER ELECTROLYTE, THAT DELIVERS THE BEST ELECTROLYTE BATTERIES USING A REDOX SHUTTLE REAGENT ADDED TO THE ELECTROLYTE. THE OVERDISCHARGE PROBLEM OF THE CELL WILL BE REMEDIED BY ADDING A SMALL AMOUNT OF A SECOND RECHARGEABLE CATHODE MATERIAL EXHIBITING A DISCHARGE PLATEAU LOWER THAN THAT OF LIMN204.
