Electrochemical Impedance of Lithium-tionyl Chloride Current Sources in the Low-frequency Range

DOI: https://doi.org/10.18500/1608-4039-2018-18-1-20-25

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.
