VS$lt;inf$gt;2$lt;/inf$gt; Nanosheets: A Potential Anode Materiral for Li-ion Batteriers

The flower-like VS 2 nanosheets were synthesized by a one-step solvothermal method.The X-ray diffraction, Raman, SEM, and TEM studies showed the growth mechanism of VS 2 flowers in detail.These experimental results indicate that the reaction temperature and time have the direct effect on the formation of VS 2 nanosheets.As anode material for Li-ion batteries, the VS 2 nanosheets exhibit an initial discharge and charge capacity are 195.4 and 90.6 mAh/g at current density of 200 mA/g.High Coulombic efficiency over 98% and improved rate capacity are achieved for the VS 2 nanosheets.All results suggest that the VS 2 nanosheets can be utilized as a promising anode material for Li-ion batteries with high power density and fast charge/discharge rates.
