- Аннотация: The purpose of this work was to study the performance of a sodium-ion battery based on the sodium vanadium phosphate /sodium titanate in the temperature range from +20 to ‒45 °C. To achieve this goal the methods of galvanostatic cycling and pulse chronopotentiometry were used. The performance of sodium-ion battery at low temperatures was found to be limited by the functioning of the negative electrode based on sodium titanate, which remains operational only at temperatures not less than ‒35 °C. The positive electrode based on sodium vanadium phosphate is efficient at temperatures down to ‒45 °C. The activation energy of sodium diffusion in the sodium vanadium phosphate and the sodium titanate is about 42 and 70 kJ / mol, respectively.
