dc.description.abstractIn the present study, we have employed an integrative strategy to synthesize a three-dimensional hierarchical electrode material consisting of NiFe2O4/r-GO nanostructures using a simple hydrothermal process and subsequently explored its electrocapacitive performance. The structural and morphological characteristics of the as-synthesized NiFe2O4/r-GO nanostructure have been accessed through X-ray diffraction (XRD), Raman spectroscopy, Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), and X-ray photospectrometer (XPS). The electrocapacitive performances of the as-synthesized sample have been evaluated by galvanostatic charge�discharge (GCD), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) using a three-electrode system with 3-M KOH electrolyte solution. As-prepared hierarchical electrode material exhibits specific capacity ? 362.46�F g?1 at a current density of 0.65�A g?1, suggesting good rate capability. Furthermore, NiFe2O4/r-GO-nanostructured electrode material displays a significant high energy ? 36.37 Wh/kg and power density as ? 276.22�W/kg. Moreover, the as-synthesized nanocomposite harvests a superior cycling stability over 5000 cycles without obvious capacitance attenuation. The NiFe2O4/r-GO provides rapid pathways for electron transfer and diminishes the ion diffusion routes due to NiFe2O4 over r-GO sheets, which ultimately results in exceptional electrochemical properties. Henceforth, NiFe2O4/r-GO nanocomposite which renders a new reasonable design to manifest more energy density and deliver maximum power may be enrooted as a promising/prospective electrode material due to its unique morphological properties, superior conductivity, and favorable cyclic stability in the field of energy storage applications. � 2024, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
