Report on the SRW: 36 p., 23 ill., 1 tab., 52 sources. Phase diagrams and concentration relations of specific electric conductivity have been studied for novel electrolyte materials for lithium-ionic batteries of new generation: LiNO3 - (CH3)2SO2, LiNO3 - (C2H5)2SO2, LiClO4 - (CH3)2SO2, LiSO3CF3 - (CH3)2SO2, LiN(SO2CF3)2 - (CH3)2SO2, LiBF4 - С3H4O3, as well as concentration relations of specific density for systems LiNO3 - (CH3)2SO2 and LiSO3CF3 - (CH3)2SO2. The data obtained significate the common character of property isotherms for all systems except for the system LiNO3 - (CH3)2SO2 that differs by the absence of any interaction between its components in liquid state. Rahman-spectra of the most characteristic systems have been obtained and the dynamics of elemental processes therein has been analysed. In electrolytes having the common character of property isotherms (LiClO4 - (CH3)2SO2) solvated cations and anions are present. In the system LiNO3 - (CH3)2SO2 the equilibrium between free nitrate-ions and those associated into ion pairs exists. In LiN(SO2CF3)2 - (CH3)2SO2 melts the solvation is complicated by conformation equilibriums of bis-trifluoromethanesulphoimide ion.
