A facile fabrication of nanometer tetragonal rod–like SnO2 as anode for lithium ion batteries

A facile and simple solid phase method has been proposed to prepare SnO 2 with SnSe as the precursor. The as-obtained powders were characterized by XRD, indicating that this material was almost pure SnO 2 . SEM and TEM images reveal that the microscopic morphology of SnO 2 material was affected by the heating rates during the formation process of SnSe. The electrochemical performance of SnO 2 as anode material for Li-ion batteries was investigated, which demonstrate that the as-prepared SnO 2 at heating rate of 10 °C min −1 and packed by copper foil exhibits as high as 899.5 mAh g –1 initial charge capacity at a current density of 0.1 A g −1 . Moreover, the SnO 2 material shows a good rate performance, suggesting its promising application as anode material for Li-ion batteries.
