摘要：

A zinc antimony composite with carbon (ZnSb/C) was synthesized as an anode material for sodium ion batteries by performing high energy mechanical milling (HEMM) and subsequent heat treatment of Zn, Sb, and Super P. The as-prepared ZnSb/C composite was analyzed with X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), which showed that the ZnSb crystallites are uniformly distributed in the carbon matrix. The ZnSb/C composite was found, despite the absence of fluoroethylene carbonate (FEC), to exhibit a desodiation capacity of 301 mAh g(-1) and an initial coulombic efficiency (ICE) of 78% as well as a good cycle life. A Zn-Sb-C mixture prepared with HEMM alone was also compared. The electrochemical reaction mechanism of the ZnSb/C composite was suggested by XRD analyses at several cut-off voltages.
