| Abstract: | The electrolyte is a very important component in lithium ion batteries. Practically, it is quite difficult to find an optimized electrolyte composition to satisfy different requirements for various applications. In this article, the nonaqueous electrolytes, including history, basic properties, solvents, lithium salts, additives, ionic liquids, gel polymer electrolytes and high voltage electrolytes are summarized briefly. Several problems needs to be solved in the future:Improving the safety of the electrolyte, extending voltage range and temperature ranges, prolonging the cycle life and service life, lowering the cost. |
