摘要

Zn_3V_3O_8 two-dimensional micro sheets are successfully synthesized by combination of solvothermal method and heat treatment. The X-ray diffraction(XRD) and field emission scanning electron microscopy(SEM) are used to characterize the structure and morphology of the samples, and the battery testing system is used to investigate its electrochemical performance. The results show that the Zn_3V_3O_8 is successfully obtained using mix solvent(water:ethylene glycol =1:1), and the sample takes on morphology of two-dimensional sheets. The initial discharge capacity for Zn_3V_3O_8 two-dimensional micro sheets is 752.0 mAh/g at 100 mA/g in the voltage range of 0.01-3 V. After heat treatment in a tube furnace at 550 ℃, the sample had the initial discharge capacity as 1152.0 mAh/g and maintained it at 901.4 mAh/g after 100 cycles. The good electrochemical performance for Zn_3V_3O_8 two-dimensional micro sheets make it possible to be used as novel anode for lithium ion battery application.
