“…The prepared electrode material (N-0.5) provides higher degree of surface capacitive contribution, which was 15, 28, 52, 62, and 68% for scan rates of 1, 2, 3, 5, and 10 mV s –1 respectively. It affirms that the diffusion contribution dominates the capacitance of the prepared electrodes at lower scan rates, and by increasing the scan rates, the surface contribution dominates due to the insufficient time for the electrolyte ions to react with the electrode material . The charge storage properties of the prepared material are further analyzed using GCD analysis.…”

“…The Ni-MOFs are synthesized using the hydrothermal method with slight modifications from the reported literatures − like a mixture of solvents and by varying the solvent ratios. In a typical synthesis procedure, 1,3,5-benzene tricarboxylic acid (BTC) was dissolved in a blended solution containing 38 mL of DMF, 1 mL of methanol, and 1 mL of double-distilled water under intense stirring for 20 min.…”

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.

Supercapacitors, designed to store more energy and be proficient in accumulating more energy than conventional batteries with numerous charge–discharge cycles, have been developed in response to the growing demand for energy. Transition metal carbides/nitrides called MXenes have been the focus of researchers’ cutting-edge research in energy storage. The 2D-layered MXenes are a hopeful contender for the electrode material due to their unique properties, such as high conductivity, hydrophilicity, tunable surface functional groups, better mechanical properties, and outstanding electrochemical performance. This newly developed pseudocapacitive substance benefits electrochemical energy storage because it is rich in interlayer ion diffusion pathways and ion storage sites. Making MXene involves etching the MAX phase precursor with suitable etchants, but different etching methods have distinct effects on the morphology and electrochemical properties. It is an overview of the recent progress of MXene and its structure, synthesis, and unique properties. There is a strong emphasis on the effects of shape, size, electrode design, electrolyte behavior, and other variables on the charge storage mechanism and electrochemical performance of MXene-based supercapacitors. The electrochemical application of MXene and the remarkable research achievements in MXene-based composites are an intense focus. Finally, in light of further research and potential applications, the challenges and future perspectives that MXenes face and the prospects that MXenes present have been highlighted.
