ELECTROPOLYMERIZED METALLO-MARCOCYCLES AS CATALYSTS IN LI/SOC12 CELLS

A RESEARCH AND DEVELOPMENT PROGRAM AIMED AT STUDYING ELECTROPOLYMERIZED METALLO-POR-PHYRINS, PHTHALOCYANINES AND TETRAAZANNULENES AS CATALYSTS IN THE LI/SOCL(2) CELL IS PROPOSED. THESE CATALYSTS WILL BE DEPOSITED AS CONDUCTIVE POLYMER FILMS ON THE POROUS CARBON ELECTRODES, PRIOR TO THEIR USE IN LI/SOCL(2) CELLS, BY ELECTROCHEMICAL OXIDATION OF THE CORRESPONDING MONOMERS IN A SUITABLE SOLVENT SUCH AS ACETONITRILE. POTENTIAL ADVANTAGES OF ELECTROPOLYMERIZED CATALYSTS INCLUDE EASE OF FABRICATION AND UNIFORM DISTRIBUTION OF THIN POLYMER COATINGS, STABILITY AND INSOLUBILITY IN THE LIALCL(4)/SOCL(2) ELECTROLYTE AND CONTROL OVER THE OXIDATION STATE OF THE CENTRAL METAL ATOM. THE FOLLOWING TASKS ARE PROPOSED FOR THE PHASE I PROGRAM. SYNTHESIS AND ELECTROPOLYMERIZATION OF AMINOAND PYRROLYL-DERIVATIVES OF COBALT TETRAPHENYL PORPHYRIN, AND NICKEL TETRAAZAANNUELEN. STUDIES TO DETERMINE THE EFFECT OF OXIDATION STATES OF THE CENTRAL METAL ATOMS OF THE ELECTROPOLYMERIZED MACROCYCLES ON THEIR CATALYTIC ACTIVITY IN LI/SOCL(2) CELLS. DISCHARGE OF LI/SOCL(2) CELLS CONTAINING ELECTROPOLYMERIZED CATALYSTS AT VARIOUS TEMPERATURES AND CURRENT DENSITIES.
