Abstract
A RESEARCH PROGRAM TO CULMINATE IN THE DEVELOPMENT OF ACTIVE MINE BATTERIES WITH LITTLE OR NO VOLTAGE DELAY AND EXCELLENT CAPACITY RETENTION DURING STORAGE IS PROPOSED. OUR APPROACH INVOLVES THE USE OF LI ANODE OVERLAYERS COMPOSED OF LI+ CONDUCTIVE POLYMER ELECTROLYTES DERIVED FROM DIMENSIONALLY STABILIZED POLY?BIS(METHOXYETHOXYETHOXIDE)PHOSPHAZENE?, KNOWN AS MEEP. LITHIUM SALT COMPLEXES OF THIS POLYMER WILL BE DIMENSIONALLY STABILIZED BY FORMING COMPOSITES WITH POLY-(ETHYLENE OXIDE) OR POLY(ETHYLENE GLYCOL) DIACRYLATE. THE EXPERIMENTAL WORK WILL INVOLVE THE PREPARATION AND CHARACTERIZATION OF DIMENSIONALLY STABILIZED MEEPBASED THIN FILM ELECTROLYTES ON LI ANODES, FABRICATION AND TESTING OF LI/SOCL2 LABORATORY CELLS, AND PRACTICAL DEMONSTRATION OF THE TECHNOLOGY IN AA-SIZE LI/SOCL2 CELLS.
