Abstract : New catalysts which improve the discharge performance of Li/SOCl2 cells have been identified. These catalysts were obtained by thermal treatment of acetylene black carbon doped with the precursors, Co(NO3)2, manganese phthalocyanine (MnPc) or vanadium phthalocyanine oxide (VOPc). The latter two materials appear to be superior to many catalysts presently available for use in Li/SOCl2 cells. Compared with uncatalyzed cells, MnPc-containing cells showed a 60% increase in cell capacity and a 10% increase in cell voltage at room temperature. VOPc-containing cathodes increased the cell capacity by 50% and cell voltage by 10% under the same conditions. The use of VOPc also resulted in significant improvements in cell performance at low temperature, e.g., at -30 C. Keywords: Catalysis, Lithium batteries, Thionyl chloride.
