The rise in need has led to the requirement of advanced smart materials to conquer the present and future disasters in energy storage and generation. Among various materials, metal organic framework (MOF) has been chosen as an active material with tunable structures, porous inorganic− organic structure, and flexibility, which allows it to play a vital role in synthesizing highly efficient energy material. In recent years, MOF materials have voiced remarkable energy storage efficiency and conversion by encouraging most of the challenges that are typically faced by transition metals, metal hydroxides, etc. Among various supercapacitor materials, nickel is a new class of electrode with excellent capacitance. To overcome some limitations, such as cyclic stability and low conductivity, researchers are working on tuning its structure and morphology. In this work, Ni-MOFs are synthesized by varying the solvent ratio using the hydrothermal method. The prepared N-0.5 MOF electrode material delivers a high specific capacity of 1004.67 C g −1 at 1 A g −1 current density. Furthermore, the hybrid supercapacitor device is fabricated using N-0.5 as the anode and activated carbon (AC) as the cathode, and its electrochemical performances are investigated in both the gel and aqueous electrolytes. All the results affirm that the prepared electrode material shows better electrochemical performance and serves as a suitable supercapacitor electrode.

“…The common method adopted to immobilize the powder MOFs onto the conductive substrates is mostly by slurry process. [ 59 ] This involves usage of inactive secondary binders and conductive carbon materials which add up to the dead mass and hinder charge transfer between the active materials (MOF) and the conductive substrate resulting in reduced specific capacitance and energy density. Therefore, MOFs directly grown on the substrates by in situ deposition without using binders, can not only resolve interfacial problem from binders and conductive materials but also ensure the strong adhesion of MOFs eliminating agglomeration and volume expansion during repeated charge discharge process.…”

Among several electrocatalysts for energy storage purposes including supercapacitors, metal–organic frameworks (MOFs), and their derivatives have spurred wide spread interest owing to their structural merits, multifariousness with tailor‐made functionalities and tunable pore sizes. The electrochemical performance of supercapacitors can be further enhanced using in situ grown MOFs and their derivatives, eliminating the role of insulating binders whose “dead mass” contribution hampers the device capability otherwise. The expulsion of binders not only ensures better adhesion of catalyst material with the current collector but also facilitates the transport of electron and electrolyte ions and remedy cycle performance deterioration with better chemical stability. This review systematically summarizes different kinds of metal–ligand combinations for in situ grown MOFs and derivatives, preparation techniques, modification strategies, properties, and charge transport mechanisms as freestanding electrode materials in determining the performance of supercapacitors. In the end, the review also highlights potential promises, challenges, and state‐of‐the‐art advancement in the rational design of electrodes to overcome the bottlenecks and to improve the capability of MOFs in energy storage applications.
