The importance of developing positive materials of lithium manganese oxide for lithium ion battery is expounded, and the applications of 3d transition metal ions (Cr3+, Ni2+, Cu2+, Fe3+) 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 LiNi0.5Mn1.5O4 has the promising application foreground for positive materials of 5 V lithium ion battery.
