УДК 544.65+621.355.9

DOI:  https://doi.org/10.18500/1608-4039-2016-16-1-30-33

Electrochemical stability of aluminum in 0.5М NaPF6 solutions in mixtures of ethylene carbonate – dimethylcarbonate – propylene carbonate and ethylene carbonate – dimethylcarbonate – diethylcarbonate has been studied with cycling voltammetry. The reality of aluminum using as current-collector in negative electrode of sodium-ion batteries is declared.

The Problems of Low-temperature Lithium-ion Batteries

DOI: https://doi.org/10.18500/1608-4039-2017-17-2-61-88

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.
