摘要：

层状LiMnO₂是高能量密度锂离子电池关键正极材料之一，是当前的研究热点。本文比较系统地综述了目前LiMnO₂材料的国内外最新研究现状，对近期的材料制备方法和掺杂改性、表面包覆改性研究的进展情况进行了详细的分析。在已有初步实验基础上提出了将液相共沉淀与高温固相法相结合制备纳米级LiMnO₂以及阴阳离子共掺杂结合熔融浸渍包覆方法提高LiMnO₂循环性能等合成及改性方法，以提高结构稳定性及循环寿命。

Abstract:

Layered LiMnO₂ is a key cathode material with high energy density for lithium-ion battery，and is a hot topic of research. In this review，the recent development of preparation and modification（doping and coating）methods of layered LiMnO₂is summarized. In order to further enhance the structural and cycle stabilities，the nanosized LiMnO₂ prepared by combining co-precipitation with the solid-state method is proposed，and further modifications by co-doping of cations and anions into layered LiMnO₂ and well-distributed surface coating by the melt-impregnation method are suggested.
