摘要

The investigation delves into the influence of different graphene oxide (GO) compositions on nickel ferrite oxide and reduced graphene oxide (NiFe2O4-rGO) based nano-composite for electrochemical performance. The present study employs a Sol-Gel auto-combustion method for synthesizing NiFe2O4 and a nano-composite of NiFe2O4-rGO. NiFe2O4-rGO (20% of GO) nano-composite electrode was one the most optimized configurations exhibiting a remarkable specific capacitance of 1709.8745 Fg− 1 and 2666.02 Fg− 1 at 1Ag− 1 and at a scan rate of 10 mVs− 1, respectively. NiFe2O4-rGO electrode also demonstrated 91% retention after 4000 cycles, showing its excellent cyclic stability and reversibility. As a result, the suggested NiFe2O4-rGO nano-composite electrode material opens new possibilities for using this composite material as a potential electrode material for future supercapacitor application energy storage devices.
