| 摘 要： | 以聚偏氟乙烯（PVDF）粉体为基材，采用预辐照接枝方法，在PVDF粉体上用乳液聚合接枝甲基丙烯酸缩水甘油酯（GMA），并采用溶液铸膜的方法制备了PVDF-g-PGMA膜。利用红外光谱（FTIR），扫描电子显微镜（SEM），压汞仪，电导率测试等分析表征手段对制备的PVDF—g-PGMA膜进行了表征。在氩气手套箱中组装成扣式电池，在电池测试系统上测试扣式电池的充放电循环性能。测试结果表明，在相同制备条件下，以PVDF-g-PGMA作为隔膜的锂离子电池性能优于以PVDF作为隔膜的锂离子电池性能。

| Abstract: | PVDF-g-PGMA powder was prepared by pre-irradiation graft polymerization technique and then the membranes were cast from PVDF-g-PGMA powder with different degrees of grafting(DG) using solvent evaporation method.The structure and the performance both of the PVDF and the PVDF-g-PGMA membranes were analyzed by means of Fourier transform infrared spectroscopy(FT-IR),scanning electron microscope(SEM),mercury porosimetry and lithium ion conductivity,respectively.After assembling 2032 coin type cell,the battery pe... |
