摘　　要：本文简单对比了高温相 LiCoO2和低温相 LiCoO2的结构和电化学性能的差别，详细介绍了 LiCoO2的各种合成方法并评述了不同合成方法、反应条件对 LiCoO2结构、形貌及电化学性能的影响，并提出了今后研究的方向。In this paper, the differences of structure and electrochemistry between HT LiCoO2 and LT LiCoO2 have been described briefly. A variety of synthetic methods of lithium cobaltate, such as high temperature solid state method, low temperature solid state method and several liquid phase technology have been reviewed and evaluated. The main factors, which affect the structure, morphologise and electrochemical performances of lithium cobaltate, have been discussed. These factors consist of used precursor,the rate of heating,reaction temperature,keeping time and the rate of cooling. The aspects of future research have been put forward, too.
