Fe2O3 electrode materials exhibit excellent electrochemical performance in electrochemical energy storage system. However, its poor electrical conductivity limits its future practical application. The binder-free Ni Co2O4@Fe2O3 composites was reasonably designed and fabricated on carbon fiber paper with NiCo2 O4 nanowires as conductive scaffold in the present investigation. The three-dimensional nanostructure of the porous Fe2O3 nanorods coated the Ni Co2 O4 nanowire arrays showed the fascinating electrochemical performance, including high specific capacitance of 262 m F/cm2 at a current density of 1 m A/cm2, and remarkable cycle stability with～74.2% capacitance retention after 4000 cycles. The excellent pseudocapacitance performance of NiCo2O4@Fe2O3 composite materials is due to synergistic effect between NiCo2O4 and Fe2O3. The results of the present work show that NiCo2O4@Fe2O3 core-shell composite electrode is expected to exhibit excellent performance in the field of supercapacitors.
