摘　　要：隔膜是锂离子电池的关键材料,在极片间起绝缘和提供离子通道的作用.本文以如何构建耐高温的隔膜、如何提高隔膜的离子电导率为重点,介绍了锂电隔膜研究及产业化技术进展,内容主要包括隔膜性能的影响因素、凝胶聚合物电解质膜、拉伸法制备隔膜及其改性、隔膜制造的新方法和新材料.最后展望了隔膜的发展前景.The separator plays very important role in the lithium ion batteries preventing electric contact of electrodes but permeable to ionic flow. This article reviews the recent progress in LIB separator research and related industrial technology. Two issues, how to build a thermal-resistant separator and how to improve ionic conductivity of the separator, are focused. This review includes four parts： the factors affecting separators＇ performance, gel polymer electrolyte, separators produced by stretching method and its modification, new methods and new materials in LIB separator fabrication. Finally, the challenges and prospects related to LIB separators are summarized.
