The flow of heat from lithium/thionyl chloride batteries, both at rest and during discharge at low to moderate rates at 37/sup 0/C, has been measured in a differential heat conduction calorimeter in an attempt to determine the effect of the discharge current on the self-discharge rate of the cells. The discharge of lithium/thionyl chloride batteries yielded exothermic calorimetric data under all conditions. The calorimetric heat output increases at low rates of discharge above the open circuit self-discharge rate. However, the fraction of the capacity that is lost due to self-discharge decreases as the discharge current increases. The self-discharge rate also decreases as the depth of discharge increases. The measured capacity loss due to self-discharge agrees with the level predicted from the calorimetric data over the range of discharge rates investigated.
