The results of the electrochemical study of the Li–S n system in the electrolytes consisted of LiN(CF3SO2)2 and tetraethylene glycol dimethyl ether in relation to the LiN(CF3SO2)2 concentration, temperature, and storage conditions are presented. The optimal concentrations of the salt component in salt-solvates were determined. These concentrations make it possible to obtain high stable values of the specific capacity in cycling and charge storage at room and elevated temperatures. It was shown that the operation stability of the electrochemical system Li–S n –LiN(CF3SO2)2 in salt-solvate solutions depends on solubility of the formed lithium disulfide, ratio composition of electrolyte and temperature.
