Modeling of Characteristics of Lithium-Sulfur Batteries Based on Experimental Evaluation of Electrochemical Properties of Electrode Materials

To model the characteristics of lithium-sulfur batteries based on the experimental evaluation of the electrochemical properties of electrode materials, the software "Battery Designer", included in the software package “ElChemLab”, was developed. The possibilities of software are described. The specific energy of lithium-sulfur batteries is compared for different surface capacitances of a positive electrode and for different amounts of electrolyte.

Studt of aluminum electrochemical stabikity in electrolytes of sodium-ion batteries

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.
