“…This work provides valuable insights into the mechanistic interpretation of mono-/multivalent cations' intercalation into VO 2 (B). 85 Ndiaye et al successfully synthesized a composite material based on vanadium dioxide and nickel-doped vanadium dioxide via a green solvothermal process using cashew nut leaves. Nickel doping was chosen because the ionic radii of V (IV) and Ni 2+ are nearly equal (0.72 A), and Ni has the advantage of low toxicity and low cost.…”

In the direction of novel energy materials, one area of intense research focus is creating new electrode materials to enhance the electrochemical performance of supercapacitors. Compared to other metal elements, vanadium has numerous valence states (+2 to +5). Materials based on vanadium oxide will show various electrochemical characteristics, which makes choosing the electrode material for a supercapacitor quite convenient. They still have a lot of room to increase the electrochemical performance of their electrode materials, which might be very useful in large-scale commercial supercapacitor applications. This review focuses on effective ways of improving the electrochemical performance of metal-and vanadium oxide-based electrode materials. To develop unique structures with more REDOX active sites, various synthesis approaches have been used, including carbon-based composites and the addition of transition metal cations. Future prospects and difficulties are addressed along with existing research approaches to clarify how advances in these materials can improve the use of supercapacitors.

“…[115,196,197] For example, high theoretical capacitance, versatile synthesis methods, and economical as well as environmentally sustainable. The theoretical capacitance is calculated using the relation between the molar mass of material (M), working potential window (V), the number of electrons transferred during redox reactions (n), and Faraday's constant (F = 96,485 C/mol), which is stated as, C = n×F/M × V. [198,199] TMOs have high theoretical specific capacitance, such as ruthenium oxide (RuO 2 = 2000 F g −1 ), [200] manganese oxide (MnO 2 = 1370 F g −1 , Mn 3 O 4 = 1264 F g −1 ), [201,202] iron oxide (Fe 2 O 4 = 3625 F g −1 ), [203] nickel oxide (NiO = 2573 F g −1 ), [204] cobalt oxide (Co 3 O 4 = 3560 F g −1 CoO = 4292 F g −1 ), [205,206] copper oxide (CuO = 1800 F g −1 ). [207] These values are significantly higher than carbon allotropes, a commonly used supercapacitor material.…”

In recent years, nanomaterials exploration and synthesis have played a crucial role in advancing energy storage research, particularly in supercapacitor development. Researchers have diversified materials, including metal oxides, chalcogenides, and composites, as well as carbon materials, to enhance energy and power density. Balancing energy density with electrochemical stability remains challenging, driving intensified efforts in advancing electrode materials. This review focuses on recent progress in designing and synthesizing core–shell materials tailored for supercapacitors. The core–shell architecture offers advantages such as increased surface area, redox active sites, electrical conductivity, ion diffusion kinetics, specific capacitance, and cyclability. The review explores the impact of core and shell materials, specifically transition metal oxides (TMOs), on supercapacitor electrochemical behavior. Metal oxide choices, such as cobalt oxide as a preferred core and manganese oxide as a shell, are discussed. The review also highlights characterization techniques for assessing structural, morphological, and electrochemical properties of core–shell materials. Overall, it provides a comprehensive overview of ongoing TMOs‐based core–shell material research for supercapacitors, showcasing their potential to enhance energy storage for applications ranging from gadgets to electric vehicles. The review outlines existing challenges and future opportunities in evolving TMOs‐based core–shell materials for supercapacitor advancements, holding promise for high‐efficiency energy storage devices.
