摘　　要：近年来,锂离子电池技术发展迅速,隔膜作为电池中的核心材料之一,决定着锂离子电池的性能,因此隔膜材料及制备技术亟需被深入研究。目前,商业化的锂电池隔膜以聚烯烃隔膜为主,制备工艺正从干法向湿法过渡,但是近几年已经发展出了不同材料体系、不同制备工艺的隔膜。本文简要介绍了聚烯烃隔膜生产技术,重点综述了非织造隔膜材料、涂层以及新型隔膜制备技术的研究成果,并展望了锂电池隔膜的发展方向。In recent years, lithium-ion battery technology has developed rapidly. As one of the core materials in the battery, the separator determines the performance of lithium-ion battery, because its characteristics influence on the influence rate, cycle and safe performance for batteries. Therefore, we need further research in the fields of separator material and preparation technology. At the present, polyolefin separator is still the main production of the commercial lithium-ion battery separator, but the preparation process is transferring from dry process to wet process. In the field of research, different material systems have been developed, such as PET, PVDF, PMIA and so on. Firstly, the production technology of polyolefin separator briefly introduced. Then the results of nonwoven separator material, coating material research, and new separator preparation technology are mainly reviewed. Finally, the outlooks and future directions in this research field are given.
