摘要

Herein we report that SnO2 nanoparticle is successfully prepared by the hydrolysis of SnCl2 as sodiumdodecyl benzene sulfonate (SDBS) is used as the surfactant. The structures and electrochemicalperformances are characterized by scanning electron microscope (SEM), X-ray diffraction (XRD),galvanostatic cell cycling and electrochemical impedance spectroscopy (EIS). The morphology of theSnO2 nanoparticle is spherical. The SnO2 nanoparticle is cassiterite type which belongs to tetragonalcrystal system with rutile structure. The results of galvanostatic cell cycling performances show thatthe SnO2 nanoparticle has high discharge specific capacity, but with relative low cycling stability. Thesample calcinated for 9h has higher discharge specific capacity and lower electrochemical impedance.
