Review of Organic-Inorganic Composite Solid Polymer Electrolyte

聚合物电解质是现在锂离子电池研究领域的热点 ,有机 -无机复合型聚合物电解质 (CSPE)是现在聚合物电解质的研究主流。在聚合物电解质中添加无机粉末 ,特别是纳米材料 ,大大改善了聚合物电解质的机械性能、离子导电性能以及界面稳定性能。对CSPE性能进行了评价 ,对在CSPE中添加无机粉末性能改善机理作了概括和探讨 。

Solid polymer electrolytes are the focus of the researches of lithium ion batteries. Among them, the researches on organic inorganic composite solid polymer electrolyte (CSPE) take as the lead at present. The properties of polymer electrolyte, such as mechanical strength, ion transport properties, and interfical stability, were improved greatly with the addition of inorganic fillers, especialy the nano scale powder. The history of CSPE was reviewed, the properties of CSPE were evaluated and the mechanism of the effect of inorganic fillers on its properties was generalized. In the end, the future of CSPE was also previewed.
