Abstract
Nanostructured nickel ferrite doped with cobalt is synthesized by co-precipitation method. The sample is
characterized using X-ray diffraction, Fourier TransformInfra Red and Transmission ElectronMicroscope. Specific
surface area and porosity analysis are performed through Brunauer–Emmett–Teller (BET) nitrogen adsorption–
desorption isotherms. The magnetic properties are also studied. Spinel cubic structure with nanoparticles and
porous surface is confirmed. The electrochemical properties of the nanostructured spinel are investigated
including the cycling performance as anode material for lithium ion batteries. The results show that the sample
has a high discharge capacity, especially the first five cycles, at current density of 2.43mA/cm2 compared to recent
performances reported at low current density (0.2 mA/cm2) for pure and composite of nanonickel ferrite. All
results and data are correlated and discussed
