摘要
评述了锂离子电池锰酸锂正极材料的重要性,介绍了3d-过渡金属离子(Cr3+,Ni2+,Cu2+,Fe3+)掺杂在锰酸锂正极材料中的应用。研究了3d-过渡金属离子掺杂对锰酸锂正极材料结构和电化学性能的影响,并提出了其影响锂离子电池充放电和循环性能的机制。展望了3d-过渡金属离子掺杂在锂离子电池锰酸锂正极材料中的发展前景,并指出LiNi0.5Mn1.5O4是非常有应用前景的5V锂离子电池正极材料。
The importance of developing positive materials of lithium manganese oxide for lithium ion battery is expounded, and the applications of 3d transition metal ions （Cr^3＋, Ni^2＋, Cu^2＋, Fe^3＋） doped in positive materials of lithium manganese oxide are introduced. Effects of 3d transition metal ion doped on structure and electrochemical performance of positive materials of lithium manganese oxide are studied, and the mechanism of influences on the cycle and charge-discharge performance of lithium ion battery is proposed. The development foreground of 3d transition metal ions doped in positive materials of lithium manganese oxide is viewed. It is suggested,that the LiM0.5Mn1.5O4 has the promising application foreground for positive materials of 5 V lithium ion battery.
