Abstract:

The reaction path of the thionyl chloride reduction from electrolytes containing dissolved aluminum chloride, with and without the addition of lithium chloride, is examined by IR-reflectance spectroscopy and cyclic voltammetry. The IR-spectroscopic investigation provides information on the sequence the various SOCL2-bearing species are reduced. In particular, onium ions accept electrons at low overpotentials while the Liyields OSCL22 species require an overpotential in excess of 1.0 V for the reduction to occur. The importance of the interplay between participating processes and the charge transfer is indicated by the scan rates and the shape of voltammograms as a function of concentration of the electroactive species. This interplay emphasizes the need for a better understanding of the role of the electrodeelectrolyte interphase during cellbattery discharge.
