✦ Synopsis

The importance of the Li/SOC12 cell using thionyl chloride as a liquid cathode has given rise to studies of the structure of the electrolytes used in this lithium cell. The electrolytes are made from LiA1C14 dissolved in SOCl, in which SO2 is formed during the discharge process. This paper deals with a structural study, using Raman spectroscopy, of solutions of LiA1C14 in pure SOCIZ and SOZ, and in mixtures of both solvents. The complexes ~Li(SOC12),~+~A.lC1,~-and [Li(S02),i+IA1C1,1-were characterized at room temperature in the pure solvents SOClz and SO*, respectively. In the ternary system LiAlCl,-SOCl,-SO, the existence of ILi(SO*, SOC1,)I+IA1C141-was established.
