A new SnO2-Fe2O3/SWCNTs (single-walled carbon nanotubes) ternary nanocomposite was first synthesized by a facile hydrothermal approach. SnO2 and Fe2O3 nanoparticles (NPs) were homogeneously located on the surface of SWCNTs, as confirmed by X-ray diffraction (XRD), transmission electron microscope (TEM) and energy dispersive X-ray spectroscopy (EDX). Due to the synergistic effect of different components, the as synthesized SnO2-Fe2O3/SWCNTs composite as an anode material for lithium-ion batteries exhibited excellent electrochemical performance with a high capacity of 692 mAh·g−1 which could be maintained after 50 cycles at 200 mA·g−1. Even at a high rate of 2000 mA·g−1, the capacity was still remained at 656 mAh·g−1.
