Effect of the Sheet Thickness on the Electrochemical Performance of 2-D SnO₂ Nanomaterial as Li Ion Battery Anode Material

Abstract:

2-D SnO₂ nanosheets with controllable thickness have been synthesized via a simple hydrothermal method. Characterization shows that the sheet thickness can be controlled from 3 to 30 nm. The correlation between the sheet thickness and the electrochemical performance of these samples as anode materials for Li ion batteries were investigated, it was found that when the sheet thickness less than 10 nm, electrodes with high charge/discharge capacities, coulombic efficiencies and stable cycling performance could be realized. The good electrochemical performance are ascribe to the ultra thin nanosheet, good flexility and porous structure of the SnO₂ anode material.
