Increased energy consumption due to rise in global population and rapidly increasing living standards has resulted in fast depletion of fossil fuel sources. Energy-storage technologies and advanced material engineering both have a significant and promising contribution worldwide to meet the issues of sustainable energy production. [1,2] Energy-storage systems, including batteries as well as supercapacitors, are among the more viable and ecologically favorable green energy solutions. Batteries supply adequate energy quantity although capacitors provide superior-quality power quantity, yet in difference, the power quantity in batteries and capacitors are lesser. Supercapacitors, on account of their distinctive competence, proved to be significant due to the integrated benefits of both. [3,4] They have wide and crucial usages in compact electronics, smart integrated devices, and other high-tech fields due to their specific properties, which consist of great capacity, high level of power density, long-lasting life period, superior charge and discharge capability, negligible maintenance, and economic and environmental safety, thus, they have globally turned into a point of research discussion in the field of energy storage. [5,6] MXene-based nanomaterials for supercapacitors have also attracted a lot of interest due to their high density, metallic conductivity, and hydrophilic nature. [7,8] Double perovskite metal oxides seem to be a kind of perovskite that has a unique structure. The ABO 3 configuration of prevalent perovskite oxide is taken by an alkaline earth/rare earth ion (Ba, Sr, Y, La, etc.) on A site and transition metal ion (Mn, Co, Fe, Cu, etc.) on B site. The characteristics of double perovskites are heavily influenced by the components that occupy these positions. The octahedral core of the adjacent six oxygen atoms is occupied by BB 0 site ions. Nonetheless, in the A 2 BB 0 O 6 composition of double perovskite metal oxides, the BB 0 sites are filled by two transition metals with an atomic ratio of 1:1. An extensive study has recently been undertaken on double perovskite oxide nanomaterials to better comprehend their energy storage, magnetic, and electrical characteristics. [9][10][11] The double perovskite materials were already synthesized through a variety of processes, including the solid-state approach, the sol-gel strategy, high-pressure fabrication, the solvothermal/ hydrothermal approach, etc. Numerous perovskite compounds had already been studied for energy-storage applications so far. [12][13][14] Although double perovskite oxide nanomaterials have shown potential for energy-storage purposes, research concerning them has been minimal. [15][16][17][18][19][20] The energy-storage and magnetic performances of some double perovskites containing yttrium at A positions, such as Y 2 NiMnO 6 , Y 2 CuMnO 6 , and Y 2 CoNiO 6 , have already been investigated.
