<p>The conversion of biomass into valuable carbon composites as an efficient non-precious energy storage electrode material have elicited extensive research interest. As synthesized partially graphitized iron oxide-carbon composite material (Fe<sub>3</sub>O<sub>4</sub>/Fe<sub>3</sub>C@C) shows an excellent property as an electrode material for supercapacitor. X-ray diffraction, High resolution transmission electron microscopy, X-ray photo-electron spectroscopy and Brunauer-Emmett-Teller analysis is used to study the structural, compositional and surface areal properties. The electrode material shows a specific surface area of 827.4 m<sup>2</sup>/g. Due to the synergistic effect of graphitic layers with iron oxide/carbide, Fe<sub>3</sub>O<sub>4</sub>/Fe<sub>3</sub>C@C hybrid electrode materials display high-performance for supercapacitor with excellent capacity of 878 F/g at a current density of 5A/g (3-electrode) and 211.6 F/g at a current density of 0.4A/g (2-electrode) in 6M KOH electrolyte with good cyclic stability.</p>
