摘　　要：介绍了锂离子动力电池正极材料锂锰氧化物中尖晶石型LiMn2O4、层状o-LiMnO2、m-LiMnO2和r-LiMnO2的晶体结构及电化学性能,阐述了制备层状LiMnO2的几种方法,重点讨论了近年来对层状LiMnO2进行的掺杂改性研究。探索掺杂不同离子对层状LiMnO2进行改性是提高其电化学性能的研究发展趋势。Crystal structures and electrochemical properties of lithium manganese oxides （ spinel lithium manganese oxide,layered o - LiMnO2, m-LiMnO2 and r-LiMnO2 ） as cathode materials of high power lithium-ion batteries have been introduced in this paper. At the same time, the preparation methods of layered LiMnO2 have been re- viewed. Study on doping modification of layered LiMnO2 has been mainly discussed. In order to improve the electro- chemical performance, the development of different ion-doping of the material are expecting to be studied.
