“…Strong coordination capabilities make transition metals suitable as the pseudocapacitive redox center of MOFs . Although the transition metal-based MOF materials such as nickel-based MOF, , cobalt-based MOF, , and Fe-based MOF , have good supercapacitance properties, poor conductivity still limits the further development of MOFs in SC . For the sake of improving the electrochemical efficiency of MOF-based SC, conductive materials (e.g., graphene and conductive polymers) are utilized to functionalize the MOFs .…”

Ni-metal–organic framework (MOF)/nano carbon (NC) electrode materials were synthesized by a one-step hydrothermal method. The prepared Ni-MOF/NC presented in the form of NC distributed uniformly on the Ni-MOF sheets, which effectively increased the specific surface area of the material and the rate of redox reaction. The Ni-MOF/NC electrode delivered 828 F/g at 1 A/g. In addition, the asymmetric supercapacitor (ASC) assembled by Ni-MOF/NC and active carbon retained 100% of specific capacitance after 5000 cycles. Furthermore, the ASC delivered energy density of 23.84 W h/kg at 849.74 W/g.

“…When the specific power of the Co/Mn-MOF// AC composite supercapacitor is 2000 W kg −1 , the specific energy is 57.2 Wh kg −1 , and the capacity retention rate is 93.51% after 5000 cycles. Kang et al [105] synthesized Ni/ Mn-MOF by solvothermal reaction using 1,4-phthalic acid as organic ligand, nickel nitrate hexahydrate, and manganese nitrate tetrahydrate as central metal ions. The prepared Ni/ Mn-MOF have a coral-like microstructure and layered pore size, with a specific surface area of 380.8 m 2 g −1 and average pore size of 13.6 nm.…”

Exploring new materials with high stability and capacity is full of challenges in sustainable energy conversion and storage systems. Metal–organic frameworks (MOFs), as a new type of porous material, show the advantages of large specific surface area, high porosity, low density, and adjustable pore size, exhibiting a broad application prospect in the field of electrocatalytic reactions, batteries, particularly in the field of supercapacitors. This comprehensive review outlines the recent progress in synthetic methods and electrochemical performances of MOF materials, as well as their applications in supercapacitors. Additionally, the superiorities of MOFs-related materials are highlighted, while major challenges or opportunities for future research on them for electrochemical supercapacitors have been discussed and displayed, along with extensive experimental experiences.
