文摘

Zn₂V₂O₇ nanorods were successfully synthesized by a hydrothermal route for the application in the Lithium ion batteries. The effects of the reacting time on the Zn₂V₂O₇ nanorods as well as the corresponding electrochemical properties were investigated. Results show that the obtained sample under the optimum condition possesses high crystallinity; the width and the thickness are in the range of 40-60 nm and 20-40 nm, respectively. Based on the observations, a possible growth mechanism of Zn₂V₂O₇ nanorods could be described as a reacting-exfoliating-splitting process. Besides, the Zn₂V₂O₇ nanorods used as anode materials in rechargeable lithium-ion battery can exhibit a highly reversible discharge/charge capacity and excellent rate property at a current density as high as 0.1 A g^?1. This might be attributed to the intrinsic characteristics of the layered structure of Zn₂V₂O₇ nanorods.
