Thermal and electrochemical properties of new low-temperature molten salt electrolytes based on LiClO4 with acetamide or ethyleneurea have been studied by differential scanning calorimetry, ac impedance spectroscopy and cyclic voltammertry, respectively. These electrolytes appear as liquid at room temperature through they are composed of two solids. DSC analysis shows that the LiClO4-acetamide electrolyte has the preferable thermal stability. The conductivity of LiClO4-acetamide electrolyte with a molar ratio of 1.0:5.5 is 1.25×10－3 S•cm－1 at 25 ℃ and 1.15×10－2 S•cm－1 at 80 ℃,and the electrochemical window of it is about 3 V.
