摘　　要：Two-dimensional conductive metal-organic frameworks(2D c-MOFs)with high flexibility in structure design and functionalization have inspired numerous research interests as promising multifunctional materials due to their porous structure,high conductivity,and rich redox active sites.This review offers a concise overview of 2D c-MOF syntheses and their applications in rechargeable batteries.The electron transport mechanism of 2D c-MOFs will be briefly introduced first.Then we discuss the designs and syntheses of 2D c-MOFs,emphasizing the conjugate structure for high conductivity and the redox activity for efficient energy storage.The electrochemical behaviors of the 2D c-MOFs in different rechargeable battery systems are summarized with attention to their structure-performance correlations and storage mechanism.Particular attention is paid to the significant applied potential of 2D c-MOFs in the Na-ion batteries(NIBs)and Kion batteries(KIBs),which are more sustainable battery chemistries but are plagued by the dissatisfactory battery performances due to the large size of the Na^(+)and K^(+).The challenges and opportunities regarding their efficient synthesis and rechargeable battery applications are also discussed.We expect this review will spark new endeavors to promote the further development of 2D c-MOFs for advanced rechargeable batteries.二维导电金属有机框架(2D c-MOFs)由于其多孔结构、高导电性和丰富的氧化还原活性位点,在结构设计和功能化方面具有很高的灵活性.作为一种极具应用前景的电极材料,2D c-MOFs引起研究人员强烈的研究兴趣.本文综述了2D c-MOFs的合成及其在可充电电池中的应用.首先简要介绍了2D c-MOFs的电子传输机理;然后讨论了2D c-MOFs的设计和合成,并重点讨论了其高导电性的共轭结构和高效储能的氧化还原活性,还总结了2D c-MOFs在不同可充电电池体系中的电化学行为,着重讨论了其结构-性能的关系和存储机理.特别地,讨论了2D c-MOFs在钠离子电池(NIBs)和钾离子电池(KIBs)中的重要应用潜力,因为这两种电池的资源更具可持续性,但由于Na^(+)和K^(+)的大尺寸而导致电池性能无法满足应用.最后讨论了2D c-MOFs高效合成和可充电电池应用所面临的挑战和机遇.这一综述有望激发研究者更多的努力,以促进2D c-MOFs在先进可充电电池中的发展.
