Effect of Lithium Source on the Electrochemical Performance of LiNi1/3Co1/3Mn1/3O2Synthesized by High Temperature Ball Milling Method

LiNi1/3Co1/3Mn1/3O2 cathode materials were synthesized by the high temperature method under the same process conditions using different lithium source (LiOH, Li2CO3). The structure and morphology of synthesized powders were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) methods, and the electrochemical performance of the material was investigated by measurements of charge and discharge. The results showed that the synthesized LiNi1/3Co1/3Mn1/3O2using Li2CO3 as the lithium source has a high electrochemical reversed. The specific discharge capacity is 155.7mAh/g under the discharge at 0.1C -rate, with a capacity retention rate of 99.7% over 25 cycles. So it has the excellent electrochemical performance.
