Abstract
THE RESEARCH EFFORT IS DIRECTED TOWARDS DETERMING THE TECHNICAL FEASIBILITY OF MORPHOLOGICALLY INVARIENT ELECTRODE/SOLID POLYMER ELECTROLYTE (SPE) JUNCTIONS FOR LONGCYCLE LIFE ELECTROCHEMICAL CELLS. ALKALI ION CONDUCTING SPES TO BE USED IN THIS PROGRAM WILL INCLUDE THOSE BASED UPON POLY(ETHYLENE OXIDE) AND THE POLYPHOSPHAZENES. NOVEL SECONDARY ELECTRODES WILL INCLUDE THE LITHIUM INTERCALATING MATERIAL LIXW02(X 1) AND HOMOGENEOUS MATRIX ELECTRODES BASED UPON THE SODIUM ION CONDUCTING SOLID ELECTROLYTE BETA"-ALUMINA. THESE LATTER ELECTRODES WILL POSSESS SELECTED TRANSITION METAL IONS SUBSTITUTED INTO SOLID ELECTROLYTE LATTICE SITES WHICH ARE CAPABLE OF UNDERGOING REDOX ELECTROCHEMISTRY. SPECIFIC CELLS TO BE PREPARED AND ELECTROCHEMICALLY CHARACTERIZED WILL INCLUDE: LIXWO2/PEO + LICF3SO3/TIS2 LIXWO2/POLYPHOSPHAZENE + LICF3SO3/TIS2 NA1.6MG0.67AL5.33M 017/POLYPHOSPHAZENE + NACF3SO3/NA1.6MG0.67AL5.33M 017 NA1.6MG0.67AL5.33M 017/PEO + NACF3SO3/NA1.6MG0.67 A1K.33M 017 WHERE M1 = CR+2/CR+3 AND M2 = FE+2/FE+3 SINCE NO CHEMICAL PHASE CHANGE OCCURS WITH THESE ELECTRODES THE MAINTENANCE OF STABLE ELECTRODE/SPE INTERFACE REGIONS ISEXPECTED TO RESULT IN HIGH REVERSIBILITY FOR THE PROPOSED CELLS. ADDITIONALLY, THE ABSENCE OF MORPHOLOGICAL CHANGES BY THE ELECTRODES IN THIS REGION WILL PERMIT SMALL SPE INTERELECTRODE SPACINGS TO BE ACHIEVED, THEREBY MINMIZING IRLOSSES.
