Abstract

Sn₂Fe/Al₂O₃/C nanocomposites are synthesized using a high-energy, mechanical milling method with thermally synthesized Sn₂Fe, Al₂O₃ and carbon (Super P) powders. The effect of Al₂O₃ addition on the microstructure of the Sn₂Fe/Al₂O₃/C nanocomposites is examined. The electrochemical characteristics of the material as an anode in lithium-ion batteries are also evaluated. High-resolution transmission electron microscopy shows that the crystallite size of active Sn₂Fe in the Sn₂Fe/Al₂O₃/C nanocomposite is smaller than that of the Sn₂Fe/C nanocomposite without Al₂O₃. A decrease in the initial irreversible capacity and enhanced cycle performance of the Sn₂Fe/Al₂O₃/C nanocomposite electrode are observed.
