Zusammenfassung: | Novel pompon-like porous SnO₂ with an average diameter of 900nm has been successfully synthesized via a simple hydrothermal process with subsequent calcination treatment at 600°C for 2h 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 100mAg⁻¹. |
