Co-Si alloy was prepared by arc melting method. The alloy consisted of 87.6% CoSi_2 phase and 12.4% CoSi phase. The CoSi_2 phase and CoSi phase were cubic structure,space groups were Fm-3m and P213,respectively,the cell parameters were 0.536(5) nm and 0.443 (7) nm, respectively. After activation, the maximum specific capacity of Co-Si alloys was 225.8 mAh/g, it had fine reversibility and cycle stability.
