Abstract:

Micro-nano structure MFe2O4(M=Zn, Co) materials were synthesized directly by hydrothermal method. The structural and morphological properties of the samples were investigated by means of X-ray diffraction(XRD) and transmission electron microscopy(TEM). The electrochemical performance of MFe2O4(M=Zn, Co) was examined by galvanostatic charge-discharge test and electrochemical alternate current(AC) impedance technique. The results show that hollow sphere CoFe2O4 and ZnFe2O4 have a reversible capacity of 1180 and 655 mA·h/g after 50 cycles, which are higher than those of solid sphere materials. At the same time, the formation mechanism of different morphology was studied.
