摘要：

Cobalt tin oxide (CoSnO3) as a novel negative electrode material for lithium-ion batteries, was synthesized through the pyrolysis of CoSn(OH)(6) precursor. The powder X-ray diffraction (XRD) analysis and transmission electron microscopy (TEM) image indicated that the product is amorphous and composed of the small square flake, which has an average size of about 70 nm. The electrochemical performance of CoSnO3 electrode material for Li-ion batteries was studied in the form of Li/CoSnO3 cell. The results show that this nanocomposite has an improving electrochemical performance comparing with the mixture of CoO and SnO2 ball milled. (C) 2003 Elsevier Science B.V. All rights reserved.
