Abstract:

The copper ferrite was prepared by an one-pot microwave assisted sintering process with cetrimonium bromide(CTAB) as the template and copper and ionic nitrates as the reactants. The morphology and microstructure of the products were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), and FT-IR spectroscopy. The as-prepared CuFe2O4 exhibits excellent electrochemical performance with the lithiation/delithiation capacity of 1202.2 mA·h/g and 873.2 mA·h/g(at the current 100 mA/g), respectively, and the capacities are maintained over 650 mA·h/g even after 50 charge/discharge cycles.
