Electrolyte solutions formed by the addition of lithium hexafluorophosphate (LiPF6) and lithium perchlorate (LiC104) to solvents obtained by mixing ethylene carbonate (EC) with propylene carbonate (PC) and dimethyl carbonate (DMC) were studied. The temperature dependence of conductivity, infrared and Raman spectra of the EC-DMC and PC-EC-DMC solvent electrolytes are discussed. The experimental and theoretical studies of characteristic vibrations of DMC are reported.
