Abstract: In this study, NiFexCo2-xO4 (FNCO) nanoparticle samples were prepared using the microwave hydrothermal technique, for x = 0.0, 0.02, 0.04, 0.06, 0.08, and 0.10, XRD, SEM, EDX, XPS, and FTIR were used to characterize the samples. The XRD shows all samples formed the cubic-spinel structure with the spatial group Fd-3m. The dip coating technique was used to fabricate the anode electrodes of NiFexCo2-xO4 samples. Cyclic voltammetry was used to investigate the electrochemical characteristics of CV, GCD, and EIS. The Specific capacitance of x = 0.06 composition, showed superior GCD characteristics with a highest specific capacitance of 640.06 F g-1 at a current density of 1 A g-1 and it was found that with the increase in frequency, the conductivity was increased.
