摘　　要：锂金属电池(LMBs)是最具潜力的下一代高能量密度存储设备,能够满足新兴产业的需求。然而,严重的锂枝晶生长、较低的库仑效率和不稳定的正极材料结构限制了它的商业应用。隔膜是LMBs最重要的组成部分之一,在很大程度上影响着电池的倍率性能、循环寿命和安全性。对隔膜表面进行涂覆可以优化其与电极材料之间的界面,从而提高LMBs性能。本文从三个方面综述了近年来聚合物隔膜涂覆的研究进展,并展望了隔膜未来的发展方向。Lithium metal batteries(LMBs),as the most promising next-generation high energy density storage devices,are capable of meeting the requirements of emerging industries.However,serious lithium dendrite growth,low Coulombic efficiency and unstable cathode material structure limit their commercial applications.As one of the most important components of LMBs,separator affects the rate performance,cycle life and safety of the LMBs to a great extent.Separator coating can improve LMBs’performance by optimizing interfaces between the separator and the anode or the cathode.This review summarizes the recent progress of polymer separator coating from three aspects,and puts forward the future development directions of the separator.
