摘要
层状LiMnO2 化合物的研究是目前锂离子电池正极材料锂锰氧化物研究工作的新热点 ,本文综述了近年来国内外LiMnO2 化合物的研究进展 ,主要阐述了具有层状和扭曲层状结构的m LiMnO2和o LiMnO2 的结构、电性能、合成和改性方法等方面的研究状况 ,重点介绍了离子交换法合成层状LiMnO2 的原因和机理。探索新的合成方法和掺杂其它金属离子改性以提高循环性能是今后LiMnO2 的研究趋势。
The development of layered LiMnO 2 as a new cathode material for rechargeable lithium batteries has been reviewed in this paper. The synthesis method, crystal structure, electrochemical properties and modification methods of layered, m LiMnO 2 and o LiMnO 2 have been discussed in detail. The reason and mechanism of layered LiMnO 2 synthesized by ion exchange reaction of Li for Na in Na x MnO 2 bronzes have been described. The development of new synthesis methods and multi substitution of the material are expecting to be studied in the future.
