Abstract

A tin-cobalt oxide film with a 3-dimensional (3D) reticular structure has been prepared by electrostatic spray deposition (ESD). X-Ray diffraction (XRD) and transmission electron microscopy (TEM) make it clear that the film is amorphous. X-Ray photoemission spectroscopy (XPS) indicates that the 3D grid is composed of SnO₂ and CoO. As an anode for the lithium ion battery, the film has 1240.2 mAh/g of initial discharge capacity, shows a gradually increasing capacity after the first cycle, and has 845 mAh/g of discharge capacity up to the 50^th cycle. The high porosity of the 3D reticular structure can provide more reaction sites on the electrode surface and accommodate volume variation of Sn particles during Li alloying-dealloying. The CoO in the complex composite film plays an important role, allowing the formation of a polymeric gel-like film to improve its electrochemical performance, preventing Sn aggregation during charging and discharging. Such a composite film can be used as an anode for lithium ion batteries with higher energy densities. © 2009 The Royal Society of Chemistry.
