A preparation method of a multi-shell loose porous core-shell structure nickel-based positive electrode material precursor

This invention discloses a method for preparing a multi-shell porous core-shell structured nickel-based cathode material precursor. This method directly controls the preparation of the precursor through partial reaction control. A seed reactor and a reaction vessel are connected to a concentration tank to control the precursor particle size. During the precursor preparation stage, the pH of the reaction system is controlled by continuously reducing the flow rate of the complexing agent solution, thereby achieving continuous coating of the seed core surface with multiple loose shells. The cathode material prepared based on the multi-shell porous core-shell structured nickel-based cathode material precursor can store more electrolyte, thus improving the cycle performance during charge and discharge. Furthermore, the loose porous structure of the cathode material prepared based on the multi-shell porous core-shell structured nickel-based cathode material precursor can provide more storage space under overcharge conditions of lithium-ion batteries, thereby improving their safety performance.
