A kind of wet synthesis method of NCMA high nickel quaternary precursor |
| abstract |
The invention belongs to the technical field of lithium ion batteries and provides a wet synthesis method of NCMA high nickel quaternary precursor. In the method, the solid microcrystalline nuclei of NCMA quaternary precursor are synthesized in the first reaction kettle, and the solid microcrystalline nuclei of the quaternary precursor are promoted in the second reaction kettle to continuously grow to a certain particle size; The solid micro nuclei of the NCMA quaternary precursor are continuously produced by the feeding method, and the second reaction kettle adopts the upper and lower two-layer feeding method to promote the continuous growth of the solid micro nuclei of the NCMA quaternary precursor. During the washing process, the NCMA quaternary precursor was washed with a certain concentration of sodium carbonate and sodium hydroxide mixed lye solution, which could wash Na to below 50 ppm and sulfur to below 800 ppm. The NCMA quaternary precursor prepared by the preparation method has uniform particle size distribution and good sphericity. The addition of aluminum will enhance the boundary strength between primary particles, improve the high energy density of the ternary precursor material, and enhance its stability and stability. cycle performance. |
