摘　　要：系统地介绍了锂离子二次电池电解质,特别是聚合物电解质及离子液体电解质的应用研究现状。开发具有高能量密度、稳定的充放电性能、循环寿命长、可塑性、高安全性与低成本的锂离子电池是当前的研究热点。离子液体具有较高的离子电导率、宽电化窗口,且无蒸汽压,而聚合物具有良好的机械加工性能。二者的结合将为锂离子电池电解质的研究提供了新的开发思路。The research on lithium rechargeable battery electrolytes is reviewed systematically in this paper. It is mainly introduced the application of polymer electrolytes and ionic liquids electrolytes used in the lithium rechargeable batteries. People focus on the improvement the properties of lithium batteries own heavy energy density, stable discharge voltage ,long-lived store, plasticility, high safety and cost currently. Ionic liquids own the good properties of high conductivity, high heat stability and negligible vapour pressure, and the polymer owns the well machining properties. The combination of the two kinds of electrolytes will provide the new methods to develop the power quality of lithium batteries.
