Na and Cl co-doping modified LiNiCoMnOas cathode for lithium-ion battery.

In recent years, ternary nickel-rich layered oxides have gradually replaced traditional binary cathode materials in the lithium-ion battery market due to their advantages of high energy density and environmental protection. However, their structural instability of cathode materials has seriously affected the cycle performance of the battery. In order to optimize the internal structure of LiNiCoMnO(NCM523), the modified LiNiCoMnOwas prepared bydoping Na and Cl wet grinding solid phase method.
