摘　　要：负极是锂离子电池的重要组成部分之一,较低的离子-电子电导率、明显体积效应以及容易粉化等问题限制着传统负极材料的发展和广泛应用。金属有机框架(MOFs)及其衍生材料的丰富孔隙有利于离子快速迁移,较大的比表面积提供更多的电化学反应活性位点,尤其是能通过改变合成工艺实现结构和化学组成调控,有效提高锂离子电池的可逆容量和循环稳定性。本文系统地总结和归纳了近年来MOFs及其衍生纳米负极材料的研究进展,梳理了不同合成方法、形貌结构与电化学性能间的相互关系,分析了这类负极材料急待解决的关键问题和面临的机遇与挑战。在尽可能充分发挥各自优势的基础上,结合有机配体和金属中心的多样性以及结构的多变性和特殊性,提出了一些改善储锂性能的有效措施和工业化应用的解决方案,展望了这类新型多孔纳米负极材料的未来发展趋势和应用前景。Anode is one of the important components for lithium ion battery.Many technical bottlenecks(such as lower ionic-electronic conductivity,huge volume effect and easy pulverization resulted from long-term charge/discharge process)prevent the development and large scale application of traditional anode materials.As a novel kind of advanced multi-functional materials,Metal-organic frameworks(MOFs)and their derivative materials behave enough pore structures promoting rapid migration of Lit and electron,and high specific surface areas providing abundant active sites for electrochemical reaction.Importantly,tunable structure and chemical composition of the MOFs and their derivative materials can be further optimized by changing parameters of synthesis process,thereby markedly increases specific capacity and cycle stability of lithium ion batteries.Herein,the recent progress in the MOFs and their derivative materials used as anode for lithium ion batteries are reviewed systematically,and the relationships between their preparation methods,microstructures,morphologies and corresponding electrochemical properties are summarized detailly.The urgent problems and challenges of this class of anode materials for lithium ion batteries are also analyzed.On the basis of resonable choosing organic ligands and metal centers,some effective measures for improving performances of lithium storage are proposed by combining with the variability and particularity of structure of the MOFs and their derivative materials,and the feasible strategies for commercialization 8 application are suggested.Finally,the perspective and future development in design and fabrication of the new types of nano porous anodes with high energy efficiencies in relation with the next generation lithium ion battery are further discussed.
