| 摘 要： | 目前，大多数聚合物固态电解质在室温下离子电导率较低，约为10–8 ~10-6 S /cm，且对温度存在着较大的依赖性，仍无法满足高性能室温固态锂电池的实际应用需要。基于此，本文先介绍了室温聚合物电解质在锂离子电池中应用的主要研究进展及其优缺点。然后，从物理调控、化学调控等多角度重点阐述了室温聚合物电解质（包括全固态聚合物电解质、准固态聚合物电解质）的制备工艺、优化与改性方法、作用机理等在电池中应用的主要研究进展和现状。最后，对锂离子电池用室温聚合物电解质存在的挑战和未来可能发展趋势进行了展望。

| Abstract: | The ionic conductivity of most solid polymer electrolytes at room temperature is low (about 10–8 —10-6 S /cm), and has great dependence on temperature. So, the polymer electrolytes cannot meet the practical application requirement for room-temperature solid-state lithium-ion batteries (LIBs). In this regard, we first summarize the main research progress and the advantage/disadvantage of room-temperature polymer electrolytes for LIBs. Then, from physical/chemical aspects, the recent developments of the preparation process, optimization and modification methods, and working mechanism of polymer electrolytes (including all-solid-state polymer electrolytes and quasi-solid-state polymer electrolytes) at room-temperature are reviewed. Finally, future research trends of solid polymer electrolytes for advanced LIBs are proposed. |
