摘　　要：电池隔膜是锂离子电池的核心组件之一,随着锂离子电池的发展而逐渐完善、创新。由于商品化程度最高的聚烯烃类微孔膜受到性能限制,亟需开发新的工艺制备综合性能优异的电池隔膜,优化隔膜的产业结构。综述了近年来使用非织造技术制备的锂离子电池隔膜,包括熔喷法、纺粘法、湿法非织造工艺及静电纺丝法,评价电池隔膜的性能及制备工艺,列举针对各个制备工艺获得的隔膜的改性方法,对锂离子电池隔膜的发展方向做出了设想与展望。Battery separators are one of the core components of lithium-ion batteries,which are gradually improved and innovated with the development of lithium-ion batteries.As the most commercially available polyolefin-based microporous separators are subject to performance limitations,it is urgent to develop new processes to prepare battery separators with excellent comprehensive performance and optimize the industrial structure of the separators.This article reviews the lithium ion battery separators prepared by nonwoven technology in recent years,including melt-blown,spunbond,wet-laid and electrospinning,evaluates the performance and preparation process of battery separators,lists specific preparation processes,and prospects the development of lithium-ion battery separators.
