Abstract:

Work was continued during the second quarter on investigating the operating characteristics of lithiumthionly chloride cells, as well as on the evaluation of cell compounds to be used in building D-size cells. The pressure build-up in sealed cells on discharge was investigated over a wide range of discharge rates. It was established that no gas is generated in the cell at the discharge rate of 1.5 mAsq cm of electrode. A steady, low-rate gassing at higher rates of discharge is related to the total capacity obtained, and independent of discharge rate in a fairly wide range of current densities, as long as the voltage of the cell remains above approximately 1.5V. A different type of gas is generated in the cell at the end of discharge and at a much higher rate. This gas redesolves in the electrolyte soon after the discharge is terminated, leaving behind only the noncondensible gas formed at discharge at a higher operating voltage. Three kinds of battery cathodes were evaluated during this period. The design calculations were made, predicting the maximum capacity and the rate capability of D-size cells made with these cathodes.
