将实验室制备的Li1.3Al0.3Ti1.7(PO4)3与PEO根据不同EO/Li摩尔比,通过溶液浇铸法技术制备了锂离子导电的PEO-Li1.3Al0.3Ti1.7(PO4)3固态聚合物电解质(SPE)膜,真空干燥后经X射线衍射分析、红外(IR)测试、示差扫描量热分析(DSC)分析和电化学阻抗测试(EI)研究了其结构与电导率性能之间的关系.证实了在固态聚合物电解质PEO-Li1.3Al0.3Ti1.7(PO4)3体系中存在络合体,并且当EO/Li=16时,这种聚合物电解质活化能最低值为0.475 eV,电导率值最佳,即25℃为2.631×10-7S/cm,100℃为1.185×10-4S/cm.
