Synthesis of LiNi0.4Mn0.4Co0.2O2cathode material prepared via carbonate co-precipitation method

Abstract

The mixed transition metal of NiSO4, MnSO4, CoSO4 has been co-precipitated with addition Na2CO3 to obtain precursor. This precursor was prepared via co-precipitation method with stirring times of 3 hours by using a magnetic stirrer. The precursor was filtrated and washed by a vacuum filter to reduce the sodium out of precursor, and then it was heated in oven to remove the H2O from precursor. The precursor was mixed with LiOH. Finally, the precursor was calcinated at 800°C and cathode was characterized with XRD. The result of X-ray Diffraction test (XRD) showed that the cathode of Li Ni0.4Mn0.4Co0.2O2 has crystallite size in the range of 7.63 - 31.46 nm.
