The critical analysis of literature of last 15 years, concerning features of low-temperature behavior of lithium-ion batteries is presented. Some generalized approaches to the problem as well as the role of main polarization components at low temperatures; features of functioning of negative and positive electrodes are reviewed. Some low-temperature electrolytes are reviewed as well.

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.

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.
