To study the effectiveness of the effect of the composition of complex compounds such as salt-solvate electrolytes, binary and ternary electrolyte systems including mixtures of complex compounds [Li • nR] X-, where n = 2 and 3 solvents, one or two of which are capable of formation complexes with a high degree of solvation. A study was made of the physicochemical and electrochemical properties of such electrolytes with components of electrode materials of lithium and lithium-ion current sources. It has been shown that with the use of iron disulphide in salt-solvate electrolytes based on dimethyl carbonate-lithium salt, the cycling processes are accompanied by the formation of lithium sulphides, the solubility of which depends both on the anionic composition of the lithium salt and on its concentration. The results of investigations of electrolytes based on solutions of lithium salts LiBOB, LiClO4, LiN (SO3CF3) 2, LiBF4, LiCF3SO3 in gels DMSO-PVDF show a conductivity sufficiently close to analogous solutions of salts in DMSO. This makes it possible to consider them promising for use in lithium current sources with an oxygen electrode.
