INFLUENCE OF THE DISCHARGE MODE OF LITHIUM-THIONYL CHLORIDE CELLS ON THEIR CHARACTERISTICS

The dependence of the discharge characteristics of Lithium-thionyl chl oride cells on the discharge regime, in particular, on its periodicity , is studied. It is shown that, in the case of discharge at a constant temperature, the current interruption practically does not affect the cell's capacity, no matter the discharge current density and the rati o of the discharge time to the open-circuit time. However, if the cell is discharged for the first time at a low temperature and the subsequ ent recuperation occurs at a high temperature, the cell capacity can b e considerably increased. This effect is explained by recrystallizatio n of poorly soluble discharge products in pores of the carbon cathode.
