Abstract: | Novel pompon-like porous SnO2 with an average diameter of 900 nm has been successfully synthesized via a simple hydrothermal process with subsequent calcination treatment at 600 °C for 2 h in air. The crystalline structure and morphology of the resulting product were characterized by X-ray diffraction, micro-Raman spectrometer, field-emission scanning electron microscopy and transmission electron microscopy. The results indicate that the product is composed of self-assembly SnO2 pompon with a high purity tetragonal rutile-like structure. The lithium storage property of the obtained pompon-like porous SnO2 was evaluated by conventional discharge/charge test, showing a high initial discharge capacity of 1895 mAh g-1 at a current density of 100 mA g-1. |
