| Summary: | The primary purpose of this research is to discover new supercapacitor electrode materials to anticipate future requirements for achieving higher-performing materials for energy storage applications. Therefore, iron cobalt oxide was investigated as a more practical and affordable technique to generate multicationic oxide materials for use as supercapacitor electrodes. In this context, one-dimensional nanostructured binary metal oxides have garnered significant attention in the field of supercapacitor (SC) applications due to their exceptional capability for fast-charge transportation. In particular, high-performance pseudocapacitor electrodes could now be made using highly aligned nanospherical arrays directly grown on conducting substrates. The iron cobalt oxide (FeCo2O4 (FCO)) electrodes on carbon fiber cloth (CFC) have porous structures constructed from several small building blocks of primary nanospherical, contributing to the nanospherical-like morphology. With a surface area of 130.04 m2 g-1, the FCO-CFC nanocomposite electrode considerably increased the pseudocapacitors’ electrochemical activity. Moreover, the FCO-CFC nanocomposite electrode demonstrated exceptional cyclic stability, i.e., 66% retention of capacitance at a current density of 10 mA g-1 after a process of 1000 cycles and a current density of 10 mA g-1 at a surprisingly high specific capacitance of 225 F g-1 for a nanocomposite electrode. In addition, the unique porous nanospherical texture, the good conductivity, and the high effectiveness can be credited to the asymmetric supercapacitor employing FCO-CFC electrodes that achieved acceptable electrochemical efficiency due to the synergistic interaction between the FCO and the CFC.
