摘　　要：锂离子电池的正极材料是影响锂离子电池性能的关键所在,正极材料应具备结构稳定,较高的锂离子脱嵌能力、电导率高等特点。综述了近几年对正极材料的研究,对α-NaFeO2结构、尖晶石结构、橄榄石结构磷酸盐(LiMPO4)等正极材料的优缺点作了相关阐述。对未来正极材料的研究提出了一定的见解。The cathode material of lithium ion battery has a key influence on lithium ion battery performance. The cathode material should have stable structure, higher lithium ion off embedded ability, and higher conductivity. The development of the cathode material in the last few years were reviewed, the relative merits of α-NaFeO2, spinel and olivine structure phosphate （LiMPO4） were elaborated. Some certain opinions for future research were proposed.
