Popis: A facile and simple solid phase method has been proposed to prepare SnO2 with SnSe as the precursor. The as-obtained powders were characterized by XRD, indicating that this material was almost pure SnO2. SEM and TEM images reveal that the microscopic morphology of SnO2 material was affected by the heating rates during the formation process of SnSe. The electrochemical performance of SnO2 as anode material for Li-ion batteries was investigated, which demonstrate that the as-prepared SnO2 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 SnO2 material shows a good rate performance, suggesting its promising application as anode material for Li-ion batteries.
