Current sources based on the electrochemical system SOC1/sub 2/-Li are characterized by a high specific energy of 800-1000 VXh/liter. During discharge the reduction of thionyl chloride takes place at the cathode. The reactive SO particles formed can further dimerize or disproportionate, and form polymeric sulfur oxides which decompose with the formation of S and SO/sub 2/. The objective of the present work was to improve knowledge of the mechanism of electroreduction of SOC1/sub 2/. The investigations were carried out at 25/sup 0/C in solutions based on SOC1/sub 2/ by chronovoltammetric and stationary galvanostatic methods. The product of the cathodic reduction of SOC1/sub 2/ is relatively stable in the investigated solutions and can be electrochemically oxidized to the original particle. The high reversibility of the electrochemical reduction of SOC1/sub 2/ at the cathode in the presence of tetraalkylammonium salts may lead to the creation of a secondary current source with improved specific characteristics provided the corresponding reversible negative electrode is selected.
