Properties of LiAlCl4 ‐ SOCl2 Solutions for Li / SOCl2 Battery

Conductance and viscosity of solutions covering a wide range of concentration (10−4–2.0M) have been measured at 25°C and for concentrated solutions these measurements have been made at several temperatures. Parameters characteristic of ion‐ion and ion‐solvent interactions and the energy of activation for conductance and for viscous flow have been obtained. Cyclic voltammograms of solutions at several concentrations have been obtained and the effect of the additives, such as , ,, and on the reduction behavior of has been studied as some of these are reduction products of . The implications of these studies on the performance and safety of the lithium‐thionyl chloride battery are discussed.
