Abstract: The great expectation has been placed on the application of Li-ion batteries in power batteries. However, the application has been hindered largely by the safety performance of Li-ion batteries which has close correlation with the properties of electrolytes. Ionic liquids with the properties of non-flammability, low-volatility and high-thermal-stability had been substituted for organic solvents as Li-ion battery electrolyte. In this review, the application of ionic liquids as Li-ion battery electrolyte is induced. It’s including the advantages/disadvantages of ionic liquids electrolyte and methods of improving electrochemical properties. Finally, the outlook for the further research is proposed.
