“…[1][2][3] In this respect, fuel cells, metal-air batteries, and electrochemical capacitors have attracted widespread attention. 4,5 As an innovative type of electrochemical energy storage device between traditional capacitors and batteries, supercapacitors (SCs) have attracted great interest due to their advantages of fast charge and discharge, high specific power, and outstanding cycling stability. [5][6][7] However, SCs still suffer from low specific energy, which is unable to respond to the growing demands of practical electronics and hybrid vehicles.…”

“…Pristine MOFs traditionally show pseudocapacitive behaviors through either redox metal ions or redox organic linkers or both in constructed MOFs. [214,215] Much effort was concentrated on utilization of monometallic Ni MOFs [138,[215][216][217][218][219][220][221][222] and bimetallic CoNi MOFs. [223][224][225][226][227][228][229][230][231][232][233] For instance, a Ni MOF constructed by mixed organic linkers of 2,3,5,6-tetramethyl-1,4-benzenedicarboxylic acid, L4, 1,4-diazabicyclo[2.2.2]octane, L34, and Ni(NO 3 ) 2 •6H 2 O grown on conductive substrate carbon fiber paper was reported to be a positive electrode, which coupled with a negative electrode prepared by thermal treatment of such a Ni MOF material (Figure 8a).…”

The preparation of electroactive metal–organic frameworks (MOFs) for applications of supercapacitors and batteries has received much attention and remarkable progress during the past few years. MOF‐based materials including pristine MOFs, hybrid MOFs or MOF composites, and MOF derivatives are well designed by a combination of organic linkers (e.g., carboxylic acids, conjugated aromatic phenols/thiols, conjugated aromatic amines, and N‐heterocyclic donors) and metal salts to construct predictable structures with appropriate properties. This review will focus on construction strategies of pristine MOFs and hybrid MOFs as anodes, cathodes, separators, and electrolytes in supercapacitors and batteries. Descriptions and discussions follow categories of electrochemical double‐layer capacitors (EDLCs), pseudocapacitors (PSCs), and hybrid supercapacitors (HSCs) for supercapacitors. In contrast, Li‐ion batteries (LIBs), Lithium‐sulfur batteries (LSBs), Lithium‐oxygen batteries (LOBs), Sodium‐ion batteries (SIBs), Sodium‐sulfur batteries (SSBs), Zinc‐ion batteries (ZIBs), Zinc–air batteries (ZABs), Aluminum‐sulfur batteries (ASBs), and others (e.g., LiSe, NiZn, H+, alkaline, organic, and redox flow batteries) are categorized for batteries.

“…Therefore, Ni-MOFs as supercapacitor electrodes have shown considerable prospects [ 28 , 29 , 30 ]. Two-dimensional (2D) and three-dimensional (3D) micro-/nanosized MOFs have received much attention for supercapacitor applications because of their large specific surface areas and low electrical resistance [ 31 , 32 , 33 , 34 , 35 ]. Cuboid Ni-MOF [ 36 ], nanoflower-like Ni-MOF [ 37 ], accordion-like Ni-MOF [ 38 ], and nanosheet-assembled Ni-MOF micro flowers [ 32 ] have been prepared through a facile hydrothermal method.…”

A series of Ni-MOF materials were synthesized via a simple hydrothermal method and can be employed as electrodes for supercapacitors (SCs). Different temperatures were selected to unveil the effect of temperature on the formation, structure, and electrochemical performance of Ni-MOF-x (x = 60, 80, 100, and 120). Ni-MOF-80 possessed a larger specific surface area with a cross-network structure formed on its surface. The synthesized Ni-MOF electrode delivered a specific capacity of 30.89 mA h g−1 when the current density reached 1 A g−1 in a three-electrode system. The as-fabricated Ni-MOF materials could be further designed and are expected to deliver satisfactory performance in practice.
