Low-frequency electrochemical impedance spectroscopy in the frequency range from 12.5 to 5 ⋅ 10⁻⁴ Hz was used to study changes in standard lithium-thionyl chloride cells during their discharge. Analysis of possible equivalent circuits describing the experimental data shows that the behavior of the cells discharged to 70% can be simulated by finite diffusion impedance in this frequency range.
