Effect of Mn–Doping Content on the Microstructure and Crystallite Size of LiNi0.85-xCo0.15MnxO2 Cathode Materials
A series of Mn-doped LiNi0.85−xCo0.15MnxO2 compounds (x= 0, 0.1, 0.2 and 0.4) were prepared by the co-precipitation method. The effect and mechanism of Mn–doping on the microstructures and crystallite sizes of LiNi0.85−xCo0.15MnxO2 cathode materials were studied. The non-equivalent substitution of Mn ions for Ni ions induces a decrease in the average valence of nickel ions. The Mn-doping promotes the formation of the single phase compounds with more ordered structure.
