Melting/freezing points of AlCl3 in saturated chloroaluminate ionic liquids [molar ratio 2:1 AlCl3:1-ethyl-3-methyl imidazolium chloride (EMIC)] are measured by differential scanning calorimetry (DSC). A critical range of temperature data (50-130 A degrees C) for AlCl3 dissolution and precipitation from saturated chloroaluminate ionic liquids is obtained. This range of temperature data is of significance to control phase transition of AlCl3 in saturated chloroaluminate ionic liquids. By applying the chloroaluminate ionic liquids to electrolytes for energy storage usage, solid AlCl3 can be partially dissolved and precipitated out during the charging/discharging cycle of energy storage equipment. Therefore, the energy density of the electrolytes is expected to be greatly improved.
