摘　　要：简述了锂离子电池的结构和充放电原理,综述了目前锂离子电池电极材料的研究进展。石墨已经被广泛用于商品化的锂离子电池。硬碳,含氢碳等由于具有很高的嵌锂容量,是最有希望的锂离子电池负极材料,已成为目前的研究热点;继层状 LiCoO2 之后,LiMn2O4 尖晶石化合物成为锂离子电池正极材料的有力竞争者。讨论了 LiMn2O4 的制备方法和结果比较;阐述了控制锂离子电池循环过程中可逆嵌锂容量与稳定性的嵌锂电极材料的结构性质。The structure and the charge-discharge principle of Li-ion battery are briefly discussed; the progress of electrode materials for Li-ion battery is reviewed in detail. Graphite has found wide applications in commercial Li-ion batteries, however, the hard carbon, especially the carbon with hydrogen is the most promising anode material for Li-ion battery owing to its high capacity, which has now become hot spot of investigation. Following the LiCoO2, LiMn2O4 spinel compound becomes the most powerful contestant. On the basis of the authors’results, the synthesis methods of LiMn2O4 and its characterizations are compared. Moreover, the structural properties of intercalation electrode materials that are related to the rechargeable capacity and stability during cycling of lithium ions are also discussed.
