Enhanced Energy Storage Performance through Controlled Composition and Synthesis of 3D Mixed Metal-Oxide Microspheres

“…These materials, including carbon-based substances, conductive polymers, and blends of transition metals [14,15], show considerable promise for enhancing energy storage technologies. Transition metal complexes with diverse oxidation states and morphologies, such as Co-Fe, Ni-Fe, Ni-Co, Ni-Mo, and Co-Mo, play a crucial role in increasing energy density and extending discharge periods through rapid Faraday redox processes [16][17][18][19]. However, these materials often exhibit lower electrical conductivity and susceptibility to accumulation.…”

“…However, these materials often exhibit lower electrical conductivity and susceptibility to accumulation. To address these challenges, researchers have explored the formation of layered binary transition metal compounds (BTMCs) by combining transition metal compounds with other electrode materials known for exceptional electrical conductivity and high specific capacitance, such as Ni-Fe MOF [20], Ni/Co-MOF@aminated MXene [21] NiCo-MOF/MXene heterostructures [22], Ni-Cu nanocomposite-modified MXene [19], transition metal quantum dots@ graphene composite [23], and dual-metal MOF-derived Co-Ni/rGO [24]. These BTMC composites have shown remarkable results in supercapacitor applications, demonstrating enhanced energy density, capacitance retention, and stability after numerous cycles [24][25][26][27].…”
