Abstract:

In the addition of Sodium alginate as a structure-directing agent, different micro-nano structures of anode materials ZnFe2O4/C were synthesized by the hydrothermal method. The structural and morphological properties were investigated by X-ray diffraction(XRD), field emission scanning electron microscopy(SEM), transmission electron microscopy(TEM) and Raman spectroscopy(Raman). The electrochemical performance was examined by galvanostatic charge-discharge test, cyclic voltammograms and electrochemical impedance spectroscopy. The results indicate that dandelion-liked ZnFe2O4/C has a reversible capacity of 2100 mA·h/g after 100 cycles at 1000 mA/g. In addition, the role of sodium alginate and the effect of different structures on electrical performance have also been investigated.
