【Abstract】 Anhydrous LiCl and Urea were mixed according to different proportion.The temperature of phase transition was determined by melting point tube method while they still keep satisfactory conductivity.According to the analysis of its phase diagram,the eutectic point was 55℃ with the molar proportion of LiCl 0.225,while its electrochemistry window was about 2.4V and shows good behavior of ionic liquids.更多还原
