Abstract: Metal organic frameworks(MOFs) have attracted great attention because of their high specific surface area, adjustable pore structure and diverse composition, and the applications of MOFs have great prospects in various fields, especially for electrochemical energy storage in which great progress has made. This article summarizes the application of MOFs based materials in the field of electrochemical energy storage for lithium-sulfur batteries, lithium-ion batteries and supercapacitors in recent years. The mechanism of MOFs and their composites as host of lithium-sulfur battery cathode was introduced in detail. The physical encapsulation and chemical coordination of MOFs on active substances were discussed. In addition, it described the improved battery performance when the MOFs derived carbon material with unique pore structure, strong conductivity and rich active sites was used as the electrode material. Finally, the MOFs based materials in electrochemical energy storage is prospected and the control of heteroatoms and the design of the channels in the MOFs-based materials are thought as the focus of future research.

Key words: metal organic frameworks, complexes, composite, electrochemistry, electrode material
