Micro-Raman mol. probe in combination with C powder microelectrodes was successfully used in the electrocatalysis study of SOCl2 reduction The discharge characteristics of Li/SOCl2 cells are usually limited by the large activation/polarization of SOCl2 on C surface. New catalysts octathiahydrophthalocyanine derivatives exhibited superior catalytic activity for reduction of SOCl2 on C surface. The catalytic mechanism and reaction on C cathodes were discussed.
