摘      要：The CoSb_3-graphite composite was prepared by ball-milling. Theelectrochemical performance of the composite material was evaluated using the lithium ion model cellLi / LiPF_6 (EC + DMC) / CoSb_3C_4. It was found that the CoSb_3C_4 composite shows higherreversible capacity than the pure CoSb_3 alloy, and its first reversible (Li-ions removal) capacityreaches 721 mA centre dot h centre dot g^(-1), which exceeds the theoretical capacity (550 mA centredot h centre dot g^(-1)) of CoSb_3C_4.
