Abstract: The novel 3D rambutan-like NiCo2O4 microspheres have been successfully coated onto surface of carbon nanofibers (CNFs) to form NiCo2O4-CNFs hybrids. The composition and microstructure of NiCo2O4-CNFs were characterized by field emission scanning electronmicroscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and X-ray diffractometer (XRD). The obtained NiCo2O4-CNFs exhibited a specific capacity of 160 mAh/g at 1 mA/cm2 in 2 M KOH aqueous solution. The specific capacity gradually increases with the increasing of cycles. And after 3000 cycles, the specific capacity still can be remained over 90%.
