Mixing process for preparing high nickel cathode material and application thereof

Abstract

The invention discloses a mixing process for preparing a high nickel cathode material and its use. The mixing process is to add a precursor and a lithium source to a mixing device for mixing to obtain a mixture. After the mixture is uniformly mixed, the mixture is mixed. While the material equipment continues to operate, spray the liquid into the mixture. After the liquid spray is completed, the material is discharged, and the obtained mixture is put into a sagger for sintering. The liquid is pure water, ethanol, nitrogen methyl pyrrolidone, and additive solution. Or one or more of additive dispersions. The spray mixing process of the present invention can make the mixture more uniform, and because of the presence of a proper amount of mist droplets, the surface of the lithium source is slightly soluble in water and can adsorb the precursor.
