摘　　要：氧化钴锂是目前锂离子蓄电池普遍采用的主流正极材料。着重叙述了氧化钴锂的高温合成技术、低温合成技术及前驱体的制备过程,也较详细地介绍了氧化钴锂的掺杂改性方法,扼要介绍了纳米技术在氧化钴锂正极材料合成中的应用。并且指出:对氧化钴锂掺杂少量元素P、B、Mg,并综合氧化钴锂、氧化锰锂及氧化镍锂等化合物的优缺点而合成复合锂锰钴、锂镍钴氧化物,仍然是这一领域的研究方向。Lithium cobalt o xide (LiCoO2) is a commonused material as the cathode for lithium ion battery. The solidstate synthesis technologies of LiCoO2 at high and low temperature a nd the preparation processes of precurso rs of LiCoO2 as well as the characteris tics of doped LiCoO2 are discussed in d etail. The application of nanotechnolog y to the synthesis of LiCoO2 is also in troduced. The LiMnCo and LiNiCo comp lex oxides synthesized by doping P, B an d Mg elements in LiCoO2, which integrat e the advantages and disadvantages of Li CoO2, LiMn2O4 and LiCoO2, are still the researching trend in this field. 
