摘要：

SnO2 nanoparticles with four different sizes of similar to 5, similar to 11, similar to 24, and similar to 39 nm were synthesized using infrared irradiation and thermal treatment. X-ray diffraction (XRD) results indicated that the particles had tetragonal rutile structure (cassiterite SnO2), and the more lattice defects were present in the as-prepared SnO2 samples. TEM and FT-IR spectra revealed that at 673 K, the disperse SnO2 nanospheres began to aggregate to form bigger size clusters; the oblate spheroids must appear. Electrochemical tests showed that particle size had a significant influence on the lithium ion insertion/desertion properties, and the similar to 11 nm-sized SnO2 nanoparticles electrodes had a superior capacity and cycling stability as compared to the similar to 5, similar to 24, and similar to 39 nm-sized ones.
