Abstract: | Porous reticular tin–iron oxide composite have been prepared by electrostatic spray deposition method for lithium‐ion batteries. The structure of depsitied electrodes are investigated by X‐ray Diffraction (XRD), which shows that the film is amorphous. Electrochemical characterization by galvanostatic charge‐discharge tests demonstrate that the conversion reactions in these electrodes enable initial discharge capacities of about 1551 mAh/g for tin–iron oxide thin film electrode, and the reversible capacity stayed in the range of 769–601 mAh/g during the successive 30 cycles. 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. Such a composite film are expected to be applied as attractive anodes for lithium‐ion batteries. |
