The SnSbCo/reduced graphene oxide (rGO) hybrids were fabricated via co-precipitation, followed by the special process of liquid nitrogen quenching and the subsequent thermal treatments. The crystal structure, morphology and electrochemical properties of the SnSbCo/reduced graphene oxide hybrids were evaluated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), galvanostatical cycling tests and EIS analysis. When the SnSbCo/reduced graphene oxide hybrids were applied as anodes for rechargeable sodium ion battery, the electrodes deliver a reversible capacity of 567 mAh g-1 at 100 mA g-1 after 50 cycles, compared with 456 mAh g-1 for bare SnSbCo. The well-improved electrochemical performance of the SnSbCo/reduced graphene oxide can be attributed to the conducting network of graphene, which greatly improves the conductivity of the electrode with volume buffering effect to prevent SnSbCo particles from aggregating.
