Continuous synthesis method of nickel-cobalt-manganese ternary hydroxide for lithium battery

The invention provides a continuous synthesis method of nickel-cobalt-manganese ternary hydroxide for a lithium battery. The continuous synthesis method is used for manufacturing nickel-cobalt-manganese ternary hydroxide through processes of nucleus growth and particle growth. The nucleus growth process is that the reaction is performed in a crystal nucleus generation kettle, and the nucleus generation is controlled in a way that the online detected pH value is 10.0-11.5; the particle growth process is that the primary growth of nucleus is performed in a primary reaction kettle, the optimized growth is performed in an optimization reaction kettle to improve the particle size distribution and morphology of particles, and a particle growth solution containing the nucleus formed in the nucleus growth process is controlled in a way that the online detected pH value is 9.5-11.0. The continuous synthesis method enables the generated nickel-cobalt-manganese ternary hydroxide to be narrower and more homogeneous in the particle size distribution, and can form particles regular in shape and size.
