Abstract
Carbon coated SnO2 hollow nanocubes were synthesized by a facile hydrothermal route. The sample with large surface area exhibits a hollow cube particle shape with an average length of ~400–500 nm. It is found that the SnO2@C−HNC shows a high discharge capacity of 799.1 mA h g−1 with the first cycle coulombic efficiency of 53.4% at the current density of 100 mA h g–1. At the high current density of 2 A g–1, it can still deliver a discharge capacity of 203.1 mA h g–1. The SnO2@C−HNC composite exhibits a good rate capability and stable cycling performance, indicating potential available as large-scale storage device.
