As a hybrid energy storage device,hybrid ion capacitors(HICs)combine the advantages such as high power density of supercapacitors and high energy density of batteries.Therefore,they are believed to have a wide application prospect in portable electronic products,hybrid electric vehicles,and many other energy storage fields.As the core component of the HICs,the electrochemical properties of electrode materials have a direct impact on the performance of the whole device.Thus,it is an urgent task to develop excellent electrode materials for improving the overall performance of HICs.Metal-organic framework materials(MOFs)are coordination polymers with ordered pore structures formed by coordination bonds between organic ligands and metal ions or clusters.The features such as possessing large specific surface area,high porosity,regular and adjustable channels,and strong designability of MOFs and their derivatives make them desirable electrode materials for energy storage areas.More recently,they are studied as electrode materials of HICs,and excellent performance is obtained.This paper reviewed the applications of MOFs and their derivatives as electrode materials for HICs.It also discussed the electrochemical performance and modification strategies of MOFs when they were used as electrode materials for HICs,which provided the theoretical basis for the design and synthesis of new MOFs-based ionic capacitor electrode materials with excellent performance.
