摘要(Abstract)：

以聚偏氟乙烯(PVDF)为基体,通过静电纺丝法制备的电池用纳米纤维隔膜存在力学性能较低、热稳定性较差等缺点,解决这一问题的主要方法是对纤维膜进行改性。简述了共混、涂覆、热处理等改性研究现状,分析了不同改性方法对纤维隔膜整体性能的影响,总结并讨论了各种改性方法的优缺点,为静电纺PVDF基锂离子电池隔膜的研究和应用提供技术和理论支持。
The electrospun polyvinylidene fluoride(PVDF) based nanofiber membranes for lithium ion battery still have many shortcomings of poor mechanical properties and thermal stability. The main method to solve these problems is to modify the structure of nanofiber membrane. In this paper, the current research status in terms of blending, coating, heat treatment of PVDF nanofiber were described briefly. The effects of different modification methods on the overall performance of PVDF nanofiber membranes were analyzed.Moreover, the advantages and disadvantages of these methods were summarized and discussed. The technical and theoretical support for the research and application of electrospinning PVDF-based lithium ion battery separators were presented.
