The electrochemical behaviors of thionyl chloride reduction in 0.11 mol dm~(-3) SOCl_2+ 0.1 mol dm~(-3) LiA1CI_4/DMF solution were studied with disc microelectrodes. For the first time, satisfactory Tafel plot with slope very nearly to 120mV/decade was obtained from steady polarization curve of thionyl chloride reduction. By analysis of the Tafel plot, it is clear that the first electron transfer of thionyl chloride reduction is a totally irreversible. The exchange current density of the first electron transfer of thionyl chloride reduction is 9.0×10~(-7)A.cm~(-2), andα value very near to 0.5.
