In the present study, nanocomposite arrays made of porous iron cobaltite nanoparticles (FeCo2O4, FCO) supported on carbon fiber cloth (CFC) were fabricated directly using a hydrothermal method in a solvent system, followed by the calcination of precursors. High capacitance and an ideal cycle life at high rates were two characteristics of the exceptional electrochemical performance of the newly developed unique nanostructure. The porous structures of the as-synthesized FCO nanoparticles on CFC cloth were fabricated using various small building blocks of primary nanoporous materials that formed interconnected structures. The FCO-CFC was evaluated as electrode materials for a supercapacitor, and they showed a high specific capacitance of 912 F g−1 at a 2 A g−1 current density in an aqueous solution of 2 M KOH. Additionally, the FCO-CFC composite electrode exhibited excellent performance moreover having long cyclic stability (retention of 90% capacitance after 10,000 cycles). The synthesis technique introduced here is scalable, facile, and economical and offers a new approach for actual applications. The key purpose of this research was to develop new materials of supercapacitor electrode for achieving super performance in various future applications of energy storage. Thus, feasible and cost-effective methods were investigated to create multicationic oxide materials, namely, FCO nanoparticles, for use as supercapacitor electrode materials. Therefore, an innovative FeCo2O4 and CFC nanocomposite, which is cheap, easy to fabricate, environmentally friendly and nontoxic, was prepared for a variety of uses from energy storage to environmental and industrial applications, such as for the batteries used in watches, phones and computer devices.
