Diagnostic of Lithium-Thionyl Chloride Cells Self-Discharge

DOI: 10.18500/1608-4039-2017-1-9-18

The problem of lithium-thionyl chloride electrochemical cell state diagnostics is described. Their after-storage performance predictability is presented. Self-discharge value diagnostics is a key issue in electrochemical cells manufacturing and utilization. The article presents major modern methods of electrochemical cell residual capacity estimation. A new method of Li/SOCl2 system self-discharge diagnostics is proposed; it is based on the measurement of initial section voltage – current strength ratio.

The voltage-ampere dependence of lithium-thionyl chloride cell residual capacity and the current values at the initial element section is determined.
