摘要
综述了近几年来锂离子电池正极材料层状多元过渡金属氧化物的研究进展,重点讨论了具有协同作用的Ni、Co、Mn三元复合型层状正极材料LiCoxMnyNi1-x -yO2 (0 <x <0 . 5 ,0 <y <0 . 5 )及部分二元过渡金属氧化物正极材料锂镍锰氧化物和锂钴锰氧化物的制备方法,以及多元素过渡金属氧化物体系的电化学反应机理及其元素配比变化对材料综合电性能的影响。进一步分析了今后几年这类层状多元过渡金属正极材料研究的可能热点及该类材料走向规模化应用的关键因素。
The progress of multi-element transition metal oxides as cathode materials for lithium ion batteries is reviewed. The synthesis methods and electrochemical reaction mechanism associated with three-element ( Ni, Co, Mn) synergetic effect of LiNi1-x-yCoxMnyO2 (0 < x < 0.5,0 < y < 0. 5) are discussed in detail, and other duality transition metal oxides including LiNi1-xMnxO2 and LiCoxMn1-xO2 are discussed. The application prospect as cathode materials for lithium ion batteries and further research orientation of these lithium intercalation multi-element transition metal oxides are pointed out.
