In the mean time , i test the separator ’ s performance , including the rate of hole 、 the performance of absorbing electrolyte and the conductance eletrochemical steady range 、 machine intensity test , and then make bettery to test its cycle performance . the test result show that , the spreading separator get better performance , when dbp ’ s percentum reach 50 % , and dry temperature reach 90 , after ultraviolet radiation disposal . the test show that , the separator has high conductance reach 6 . 1 10 - 3s / cm ( 25 ) , and the machine intensity can reach 3 . 92 mpa , this separator can meet the need of making bettery , the bettery capability will go down after 30 cycle . and the bettery show worse performance under high temperature , under 70 , the bettery will get fire . making the intensified seprator , i find that when dbp % : pvdf % = 40 % : 60 % , dbp % + pvdf % : sio2 % = 70 % : 30 % , the separator get 但用其制备的电池循环30周期后容量发生衰减,并且电池高温性能差, 70下电池燃烧;强化聚合物膜的最佳制备配比条件为: dbp : pvdf为40mass % : 60mass % , dbp含量与pvdf含量之和与纳米sio2含量比值为70mass % : 30mass % ;强化电解质隔膜的室温离子电导率也可达4 10 - 3s / cm左右,完全能满足聚合物锂离子电池的使用需要;机械强度远远大于流延法制得的隔膜,达到108 . 84mpa 。

Making spreading separator , and research the influence of dbp ’ s percentum and the dry tempareture . in order to find the influence of the succedent disposal , i have reseached the water disposal , the ultraviolet radiation disposal and the water disposal with the ultraviolet radiation disposal . making separator by dipping method , and research the influence of dbp ’ s and inorganic additive nm sio2 ’ s percentum mainly 探讨了增塑剂邻苯二甲酸二丁酯( dbp )含量以及干燥温度对隔膜性能的影响;研究了紫外照射、水浴后处理对隔膜机械强度及其他性能的影响;考察了增塑剂含量以及无机添加剂纳米sio2含量对强化电解质隔膜性能的影响。
