摘要：

When natural graphite (NG) is doped with different ratios of carbon nanotube(CNT), a composite material formed by nano-C and graphite-C was obtained. The measurements show that the complex with 10% CNT(in mass fraction) possesses the best electrochemical performance. Undergoing charge/discharge cycles for 20 times, the charge capacity of this material is obviously improved, 15.9% more than that of pure graphite without CNT. Due to the mid-hollow structure and anti-collapse property for CNT, this composite material would increase charge/discharge capacity and stable cycle property.
