金属有机框架材料用于锂电池负极的研究进展

Research progress of MOFs applied as anode for lithium-ion battery

金属有机框架材料(MOFs)因高孔隙率、结构可控和氧化还原活性可调等特点被广泛应用于锂离子电池负极的研究。分析了近几年来MOF基材料在锂电池负极的研究进展;指出MOF基材料固有的多孔结构有利于锂离子迁移,金属中心和有机配体可以作为氧化还原物质使用,具有孔隙可逆储锂和可逆化学反应储锂两种不同的储锂机制;讨论了近几年来MOF基衍生物、复合物在锂电池负极的应用;展望了MOFs在锂电池负极的发展前景。

Metal-organic frameworks(MOFs)have been widely applied as anode for lithium ion batteries due to their high porosity,controllable structure and tunable redox activity.The recent progress of MOF-based materials in the field of Li-ion battery anodes was reviewed.It's pointed out that the porous structure of MOFs is beneficial for lithium ion migration,the unsaturated metal cluster or ion and functionalized organic ligand can be used as redox substance,and there are two different lithium storage mechanisms of reversible chemical reaction and reversible pore.The recent application of MOF-based derivatives and complexes in Li-ion battery anodes was discussed.The develop-ment of MOFs in Li-ion battery anode was prospected.
