摘　　要：比较了两类不同的层状LiMnO2———m-LiMnO2和o-LiMnO2的结构和性质。解释了层状LiMnO2结构不稳定、易向尖晶石结构转变的原因。介绍了层状LiMnO2的改性方法,尤其是不同元素掺杂和表面改性。The structure and performance of two different layered LiMnO2-m-LiMnO2 and o-LiMnO2 were compared. The reasons of the structure instability, easy transforming into a spinel structure of layered LiMnO2 were explained. The methods to improve the performance of layered LiMnO2, especially doping different elements and surface modification were introduced.
