摘要:通过对成膜过程的控制,可形成不同形貌的聚甲基丙烯酸甲酯(PMMA)/聚偏氟乙烯(PVDF)凝胶聚合物膜。通过共混成膜的方法,得到无孔共混膜;通过先成膜再交联的方法,得到稀孔交联膜;通过先交联再成膜的方法,得到多孔交联膜。它们的离子电导率顺序为:多孔交联膜〉无孔共混膜〉稀孔交联膜。采用多孔交联膜的原理型电池以0.2C在3.0~4.3v充放电,第50次循环时的容量保持率大于92%。
Poly (methyl methacrylate) (PM MA)/poly (vinylidene fluoride) (PVDF) gel polymer membranes with different morphology were formed by controlling the membrane formation processes. The nonporous blending membrane was obtained by blending and coating, the less-porous cross-linking membrane was obtained by cross-linking after coating, the porous cross-linking membrane was obtained by cross-linking before coating. The order of their ionic conductivity was the porous cross-linking membrane 〉 the nonporous cross-linking membrane 〉 the less-porous cross-linking membrane. The capacity retention rate of the principle cell using the porous cross-hnking membrane at the 50th cycle was higher than 92% when charge-discharged at 0.2 C in 3.0 - 4.3 V.
