ABSTRACT:
A class of improved catalysts for use in high-rate active-metal non-aqueous cells which show excellent performance enhancing properties are disclosed. These comprise a class of metal porphyrin complexes which catalyze the electrochemical reduction of oxyhalides. The preferred porphyrin compounds include tetraphenyl porphyrin (TPP) and tetramethoxyphenyl porphyrin (TMPP). The preferred complexed metals are cobalt and iron yielding (CoTPP), (FeTPP), CoTMPP) and (FeTMPP), respectively. A polymeric form of TPP complexed with cobalt (CoTPP)n or iron (FeTPP)n is extremely insoluble in the typical Li/SOCl.sub.2 cell electrolyte and may be used very successfully in active cell configurations is also disclosed.
