中文摘要：

介绍了热处理工艺对中间相炭微球（MCMB）微观结构的影响及其热处理后用作锂离子电池的电化学性能。指出MCMB经2500℃以上高温处理虽然具有良好的充放性能，但是其理论充放电仅为372mAh／g，而MCMB经500～1500℃热处理后虽然具有高达1190mAh／g的首次充电容量，但是循环性能极差。而在过渡金属化合物存在下MCMB经低于1000℃低温修饰处理可获得充放容量高于500mAh／g、循环性能良好的锂离子电池负极材料，为轻量化、高容量锂离子电池负极材料的开发提供了新的发展方向。

英文摘要：

In the paper the influence of heat treatment on MCMB microstructure and electrochemical performance of lithium ion batteries after heat treatment are discussed. It＇s indicated that good charge-discharge performance of MCMB can be reached by thermal treatment above 2500℃, but its academic capacity is only 372mAh/g. At the same time, the first charge capacity of MCMB can reach 1190mAh/g when it is treated at 500～1500℃ ,but its cycling performance is very poor. However, anode materials have charge-discharge capacity no lower 500mAh/g and good cycling performance can be obtained by treating MCMB at a temperature below 1000℃ in the presence of transition metal compound.
