Abstract:

Metal-organic framework(MOF) plays an important role in gas separation, energy storage, catalysis and other fields due to its excellent surface area, numerous active sites, adjustable pore size range and flexible framework structure. In recent years, the use of MOF materials with high surface area, permanent pores and inherent redox active sites as electrode materials for supercapacitors has attracted close attention from researchers. This paper starts with the application research of MOF in the field of supercapacitors, introduces the effects of their properties and structures on the electrochemical properties of supercapacitors emphatically, and elaborates the research progress of MOF property regulation and structure design. First of all, the conductivity of MOF is a key performance that affects the energy density and power density of supercapacitors, and the special structure of the material directly affects the conductivity. Secondly, the abundant active sites and adjustable pore size of MOF create conditions for its improvement of electrical conductivity. In addition, the structural stability of MOF is closely related to the cycling performance of supercapacitors. The construction of stable structure is an important prerequisite for enhancing the cycling performance of supercapacitors. Finally, the future research of MOF in the field of supercapacitors is prospected. The structure regulation is still an important research direction in this field.
