The effects of continuous and semi-continuous synthesis processes of precursor on the structure and performance of precursor materials and nickel-rich NCM cathode materials were explored. The results show that primary particles of the precursors synthesized by these two processes are quite different in morphology, leading to the difference in structure of primary/secondary particles and electrochemical property of the correspondingly synthesized cathode materials. These two cathode materials present little different performance in a button half cell, but significant difference in a soft pack battery. The nickel-rich cathode synthesized by the semi-continuous process has a lower impedance at a low state of charge, and retains 87.61% of its capacity after 750 cycles at 45 ℃, much higher than the retention rate (77.65%) of the nickel-rich cathode synthesized by the continuous process. It is concluded that the semi-continuous synthesis process for precursor is superior in the production of nickel-rich cathode materials.
