Zn 3 V 3 O 8 was successfully synthesized by mix solvothermal method. The NH 4 F was used as an additive (agent) to control morphology of Zn 3 V 3 O 8 . It was found that suitable percentage concentration of NH 4 F could control morphology of Zn 3 V 3 O 8 as two-dimensional (2D) sheets. The X-ray diffraction (XRD) and field emission scanning electron microscopy (SEM) were used to characterize the structure and morphology of the samples, and the battery comprehensive testing system was used to study its electrochemical properties. The results showed that the Zn 3 V 3 O 8 was successfully obtained by mix solvothermal method (water: ethylene glycol = 1:1), and 2D Zn 3 V 3 O 8 sheets was synthesized by adding NH 4 F as soft template. The initial discharge capacity for 2D Zn 3 V 3 O 8 micro sheets is 1709.6 mAh·g −1 at 100 mA/g in the voltage range of 0.01–3 V. After 100 cycles, it could maintain at 1372 mAh·g −1 . The Zn 3 V 3 O 8 two-dimensional micro sheets behaved good rate performances also. So Zn 3 V 3 O 8 two-dimensional micro sheets synthesized by this way is a novel and promising anode material for lithium ion battery application.
