Abstract

Amorphous carbon-coated nano-scale SnO2 powders were prepared by pyrolyzing the mixtures of starch and Sn(OH)4. The structure, morphology and properties of the sample were investigated by XRD, SEM，TEM，STEM-EDX and discharge-charge cycle. The results of XRD, SEM, TEM and STEM-EDX show that amorphous carbon of the sample is flaky and amorphous Carbon-coated SnO2 particles (20-50nm) are distributed in amorphous carbon uniformly. The results of discharge-charge cycle show that the different proportions between SnO2 and amorphous carbon lead to different discharge-charge performances. The specific capacity of the sample (SnO2∶C＝1∶1) reaches 404mAh/g which is even stable in twentieth cycle.

Key words： lithium-ion battery; anode；SnO2; amorphous carbon-coated
