Cathode‐Limited Li / SOCl2 Cells

The ambient temperature discharge characteristics of cathode‐limited Li / SOCl 2 cells have been investigated at discharge rates ranging over five orders of magnitude (from about 2 μA/cm 2 to about 0.5 A/cm 2 ). The cell voltages and discharge capacities (per unit cathode volume) are compared as a function of discharge current density. The use of alternative cathode materials which catalyze the electroreduction of SOCl 2 is discussed, as are the dependencies of the average load voltage and the cathode utilization efficiency upon cathode thickness at high discharge rates. The relationship between the interelectrode spacing and the high rate discharge characteristics of cathode‐limited Li / SOCl 2 cells has also been investigated.
