摘　　要：锂硫电池因出色的理论容量和能量密度被认为是下一代最具潜力的储能体系之一,但其商业化仍受限于可溶性多硫化物在电解液中的穿梭效应。在隔膜上涂覆金属有机框架材料(MOFs)是进一步提高锂硫电池性能的有效手段。综述了MOFs及其复合材料对锂硫电池隔膜的改性作用;阐述了MOFs及其复合材料改性隔膜对穿梭效应的抑制策略,并提出了修饰锂硫电池隔膜需要解决的问题和发展前景。The lithium-sulfur batteries are considered to be one of the most potential energy storage systems in the next generation due to their excellent theoretical capacity and energy density,but their commercialization is still limited by the shuttle effect of soluble polysulfides in the electrolyte.Coating the separators with metal-organic framework materials(MOFs)is an effective means to further improve the performance of lithium-sulfur batteries.The modification effects of MOFs and its composites on the separators of lithium-sulfur batteries were reviewed.The suppression strategy of MOFs and its composite modified separators on the shuttle effect was described,and the problems to be solved and the development prospect of the modified lithium-sulfur battery separators were put forward.
