The electrochemical properties of β-Zn4Sb3 and Zn4Sb3C7 as new lithium-ion anode materials were investigated. The reversible capacities of the pure Zn4Sb3 alloy electrode and 100h milled Zn4Sb3 in the first cycle reached 503 and 566mAh/g, respectively, but the cycle stability of Zn4Sb3 whether milled or not were obviously bad. It was demonstrated that cycle stability of Zn4Sb3 could be largely improved by milling after mixing with graphite. It was shown that Zn4Sb3C7 composite has a lithium-ion extraction capacity of 581mAh/g at the first cycle and 402mAh/g at 10th cycle.
