The Two Electron Oxidation of Cobalt Phthalocyanines by Thionyl Chloride: Implications for Lithium/Thionyl Chloride Batteries

Abstract

Cyclic voltammetry, DPV and electronic spectroscopy are used to study the reaction between thionyl chloride and cobalt phthalocyanine. SOC12 reacts with (Co(I)Tn Pc(2-)) and Co(II)Tn Pc(2-) to give two-electron oxidized species. Implications for Li/SOC12 batteries are discussed. Thionyl chloride also forms a mono SOC12 adduct with Co(II)TnPc(2-). Driving forces (Delta E values) have been calculated for CoTnPc comproportionation and CoTnPc + SOC12 reactions. Rest potential measurements of a Li/SOC12 cells show that addition of A1C13 stabilizes the LiC1 product as LiA1C14. A catalytic two-electron mechanism is indicated for the reduction of thionyl chloride in a Li/SOC12/(CoTnPc,C) battery. Keywords: Electric batteries; Phthalocyanine; Lithium battery, Thionyl chloride; Two electron oxidation; Aluminum; Cobalt.
