Fe2O3 electrode materials exhibit excellent electrochemical performance in electrochemical energy storage sys-tem.However,its poor electrical conductivity limits its future practical application.The binder-free NiC-O2O4@Fe2O3 composites was reasonably designed and fabricated on carbon fiber paper with NiCo2O4 nanowires as conductive scaffold in the present investigation.The three-dimensional nanostructure of the porous Fe2O3 nanorods coated the NiCo2O4 nanowire arrays showed the fascinating electrochemical performance,including high specific capacitance of 262 mF/cm2 at a current density of 1 mA/cm2,and remarkable cycle stability with～74.2％ capacitance retention after 4000 cycles.The excellent pseudocapacitance performance of NiC-O2O4@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 perfor-mance in the field of supercapacitors.
