摘要
Abstract The conductivity of 1.8 M LiAlCl4/SOCl2 electrolyte solutions showed the greatest temperature dependence at 298 K. Raman spectra results suggest that the adduct compound is Li(SOCl2)y−x(SO2)x+. The structural changes in LiAlCl4/SOCl2 electrolyte solutions were analyzed using 7 Li NMR spectroscopy. The 7 Li spin-lattice relaxation rate indicated a change in the ionic structure of the electrolyte near 298 K which was confirmed by measuring the chemical shifts and relaxation times under various temperatures and concentrations. The concentration effects on conductivity of LiAlCl4/SOCl2 electrolytes were also investigated. All experimental results suggest that the transition phenomenon in LiAlCl4/SOCl2 electrolyte solutions is related to the transformation between Li(SOCl2)y−x(SO2)x+ and Li(SOCl2)y+.
