Abstract:

ZnFe2O4 materials with spinel structure were synthesized from ZnCl2 and FeCl3.6H2O by solvothermal method. Crystal structure and surface morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and fourier transform infrared spectrum (FT-IR). Electrochemical performance was analyzed by constant current charging-discharging technique and cyclic voltammetry. The results showed that the particle size was about 250 nm. As an active material for lithium-ion batteries, the nano ZnFe2O4 material delivered a reversible capacity of 933.1 mAh/g at a current density of 50 mA/g. The specific charge capacity slightly decreased to 813.5 mAh/g, with a retention of 87.2% after 100 cycles. Furthermore, the material was able to release a capacity of 355 mAh/g at a current density as high as 400 mA/g, which demonstrated reasonable rate performance and moderately fast charge/discharge capabilities. Data from this study indicated that ZnFe2O4 nano-material prepared by solvothermal method is a promising anode material for lithium-ion battery with high capacity and superior cycling stability.
