An amorphous nanosized tin-zinc composite oxide as a high capacity anode material for lithium ion batteries

A new anode material for lithium ion batteries, ZnSnO3, was prepared through the pyrolysis of ZnSn(OH)(6). The powder XRD analysis and TEM image demonstrated that the product is amorphous, the powder particles take the shape of square flake and the size is about 70 nm. Electrochemical measurements showed that the reversible capacity of the ZnSnO3 electrode was more than 800 mAh.g(-1).
