摘要为了改善锂离子电池的高温安全性和充放电性能，以聚苯醚树脂为成膜材料，采用静电纺丝技术制备了纳米纤维锂电隔膜，对隔膜的形貌、结构、电解液亲和性和耐高温性进行了系统测试，并将该纳米纤维膜装配到电池中进行充放电性能测试。结果显示：聚苯醚隔膜的纳米纤维直径约为260nm，纤维交错形成均匀的孔道（平均孔径约500nm），其孔隙率达到74%以上，为聚烯烃隔膜的2倍左右；聚苯醚树脂的电解液亲和性和高孔隙率强化了隔膜的电解液吸收和保持能力，其吸液率约为310%；在150℃，60min的热处理条件下，该隔膜的尺寸收缩率几乎为零。电池性能测试表明，聚苯醚基纳米纤维膜显示出更优的放电倍率性能和循环性能。

Abstract：To improve the high temperature safety and charge-discharge performance of lithium-ion batteries, a novel polyphenylene oxide-based nanofiber separator was facilely prepared by electrospinning method and investigated in lithium-ion batteries. Some investigations including morphology, microstructure, electrolyte wettability, thermal resistance and cell performance were carried out. The results demonstrate that the polyphenylene oxide-based separator with fiber diameter of 260 nm exhibits uniform porous structure (with average pore size of 500nm). The porosity is up to 74%, which is about one time higher than that of polyolefin separators. This separator also shows excellent electrolyte uptake (310%) and thermal stability at 150℃ for 60min.Cell performance tests show that the nanofiber separator exhibits better discharge performance and cycle performance compared with the commercial PE separator.

Key words： battery nanofiber separator porosity thermal resistance electrochemical performance
