This thesis describes an investigation of some of the factors which govern the operation of the commercially important Li-SOCl2 cell. Electrode processes at lithium anodes and C-SOCl2 cathodes have been studied using the technique of Faradaic impedance. A kinetic interpretation of the results has been advanced. Additionally some aspects of the formation and nature of LiCl films, which frequently cover the anode surface have been revealed from the decomposition of the numerical data. The impedance study further yielded kinetic data relating to the lithium dissolution process. Complementary preliminary studies of the impedance of glassy carbon-SOCl2 cathodes have shown that the cathode process is complicated.
