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


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.

Применение акустических методов для~диагностики химических~источников тока


This article discusses the issue of increasing the reliability of evaluation of the depth of discharge of primary chemical sources of electric current by means of acoustic methods, which have never been used for this purpose, and integration of data of acoustic spectroscopy and impedance and noise spectroscopy.

Investigation of the Initial Stages of Anode Dissolution at High-frequencies in Lithium tionyl Chloride Cells


Impedance spectroscopy was used to study the initial stages of lithium anode dissolution in SAFT LS-33600 cells at frequencies more than 35 Hz. It was found that experimental results can be described by the dissolution of metals covered by a passive film, including the stages of film dilatation and breakdown of the film.
