“…27 Material for electrodes can be classified into different categories, such as metal oxides, metal sulfides, metal phosphate, perovskite materials, metal-organic framework, carbonaceous materials, and conducting polymer-based. 23,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] Metal oxide electrode materials have higher specific capacitance, energy density, and chemical stability. Due to its high theoretical capacitance and quick Faraday redox reaction, RuO 2 is an excellent pseudocapacitive electrode material; nevertheless, SC applications are hampered by RuO 2 's high cost and environmental toxicity.…”

“…Although some oxides are commonly found (oxides of cobalt, nickel, zinc, etc) and have high specific capacitance, with some electrical conductivity issues, conductors can be substituted for RuO 2 . [28][29][30][31][32][33] Metal sulfides have drawn much interest as a viable electrode material for pseudo capacitors mainly because of their inexpensiveness, ecological sustainability, excellent specific capacitance, and readily accessible electron conductivity. Still, they have a low surface area.…”

Supercapacitors are gaining popularity as energy storage devices (ESDs), and their electrode materials strongly influence their performance. There is no doubt that supercapacitors are capable and reliable ESDs for producing high power even when they operate at low energy levels. Surface modification of the materials can improve the power and energy density of the materials, which is beneficial for enhancing the electrochemical performance of the supercapacitor. During the past few years, more research has been reported to develop new electrode materials for improving the supercapacitors' energy density, charge retention, specific capacitance, stability, and rate performance. This review focuses on the execution of progressive organic-based electrode materials called metal-organic frameworks (MOFs) in the supercapacitor, which offer high electrode stability, capacity, and adjustable pore size, making them promising for electrochemical energy storage applications (supercapacitors) despite challenges. The main purpose of this review is to explain the MOFs-based electrode materials and their progress in the supercapacitor field. Because MOFs allow many attributes like multiple dimensions, additional accept ratio, and higher surface area, MOF fabrication provides stronger bonding between metal and organic linkers than traditional material, making them progressive materials for supercapacitors. Finally, the challenges and perspectives of MOFs-based electrode materials are discussed.

“…The peaks confirmed that the increase in the scan rate caused the shifting of the oxidation peak from lower voltage to high voltage, and the reduction peak moved in the reverse direction. It is believed that the oxidation peak fluctuates in a positive potential direction, as the reduction peak fluctuates in a negative direction, resulting mainly from the polarization effect on the oxidation peaks ( Asghar et al, 2022b ). The GCD plots of ZnCo 2 O 4 are displayed in Figure 11B , which has a plateau portion that confirms the pseudocapacitive nature of the ZnCo 2 O 4 electrode.…”

A significant amount of energy can be produced using renewable energy sources; however, storing massive amounts of energy poses a substantial obstacle to energy production. Economic crisis has led to rapid developments in electrochemical (EC) energy storage devices (EESDs), especially rechargeable batteries, fuel cells, and supercapacitors (SCs), which are effective for energy storage systems. Researchers have lately suggested that among the various EESDs, the SC is an effective alternate for energy storage due to the presence of the following characteristics: SCs offer high-power density (PD), improvable energy density (ED), fast charging/discharging, and good cyclic stability. This review highlighted and analyzed the concepts of supercapacitors and types of supercapacitors on the basis of electrode materials, highlighted the several feasible synthesis processes for preparation of metal oxide (MO) nanoparticles, and discussed the morphological effects of MOs on the electrochemical performance of the devices. In this review, we primarily focus on pseudo-capacitors for SCs, which mainly contain MOs and their composite materials, and also highlight their future possibilities as a useful application of MO-based materials in supercapacitors. The novelty of MO’s electrode materials is primarily due to the presence of synergistic effects in the hybrid materials, rich redox activity, excellent conductivity, and chemical stability, making them excellent for SC applications.

“…Among these devices, supercapacitors have seen significant development in the last decade and have the potential to bring about major advances in the field of energy storage [1][2][3][4][5]. Current research and development patterns predominantly feature the use of carbonaceous materials in supercapacitor fabrication because of their excellent cycling stability and high specific capacitance [6][7][8][9]. However, they suffer from limitations in specific energy density and cell voltage.…”

This research addresses the pressing demand to enhance energy density and power in energy storage devices, including batteries, fuel cells, and supercapacitors. Here, NiMn2O4 is synthesized using the urea combustion method. Characterization techniques, including powder X-ray diffraction, field emission scanning electron microscopy, and BET analysis, are employed to investigate its properties. The diffraction peaks showed that NMO had a face-centered tetragonal structure, and the Scherrer equation was used to figure out the average crystallite size (t) as 8.73 nm. Its electrochemical behavior is extensively evaluated through cyclic voltammetry and galvanic charge-discharge measurements. The findings indicate that the fabricated NiMn2O4 electrodes exhibited remarkable specific capacitance and exceptional cycling stability, retaining 97% of their initial performance over 10000 cycles. The specific capacitance of the electrode from GCD was obtained 80 F/g at a current density of 0.25 A/g. This study highlights the potential of NiMn2O4 as an electrode material for high-performance electrochemical supercapacitors, offering a viable solution for advancing energy storage technologies.
