Herein, Fe-doped tin oxide is presented for the first time as new high-capacity lithium-ion anode material. Pure SnO2, Fe-doped SnO2 (Sn0.9Fe0.1O2, SFO), and carbon-coated SFO (SFO-C) were synthesized and morphologically and electrochemically characterized by X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, Brunauer-Emmet-Teller method, and galvanostatic (dis-) charge measurements. Doping SnO2 with Fe results in a substantially enhanced reversible specific capacity and coulombic efficiency. After ten cycles the reversible capacity of SFO-C was about 1519 mAh g(-1), i.e., almost twice the specific capacity obtained for pure SnO2 (764 mAh g(-1)). Moreover, limiting the reversible capacity to 600 mAh g(-1) shows the great potential of SFO-C for application in lithium-ion batteries. (C) 2015 The Authors. Published by Elsevier B.V.
