摘　　要：碳材料用作锂离子蓄电池的负极材料导致了可充锂电池的飞速发展 ,但碳材料的结构、性能及其贮锂性能的影响至今仍然是有争议的课题。锂离子蓄电池应用领域的迅速扩大对负极材料的嵌锂性能提出更高要求 ,理论上也相应地提出了一些解释高嵌锂容量的新机理。在介绍中间相沥青炭微球 (MCMB)结构的基础上 ,综述近年来MCMB在嵌锂模型方面的一些主要进展 。Rechargeable lithium battery is developed rapidly due to the adoption of carbon materials as the anode material for Li ion battery. However, the structure and properties of carbon materials is still the disputed subject as well as its effect on Li ion intercalation property. The current rapid extension of Li ion battery application arises high requirement to anode material on the Li ion intercalation property, and the new theoretical mechanism for explaining the high Li ion intercalation capacity is presented accordingly. The major progresses of meso carbon microbeads (MCMB) on Li ion intercalation model are reviewed and its developing trend is presented on the basis of introducing MCMB structure.
