| titleOfInvention | Preparation process of particle high-dispersion nickel-cobalt-manganese ternary precursor |
| abstract | The invention discloses a preparation process of a particle high-dispersion nickel-cobalt-manganese ternary precursor, which relates to the technical field of lithium ion battery anode materials and comprises the following steps: preparing a nickel-cobalt-manganese soluble salt aqueous solution, an alkali solution and an ammonia aqueous solution; under the protection of nitrogen, adding deionized water and ammonia water into a reaction kettle as a base solution; adding an alkali solution into the base solution to adjust the pH value to 11.4-11.7, adding hydrazine hydrate, and heating; under the condition of no stirring, adding the nickel-cobalt-manganese soluble salt aqueous solution and the alkali solution into a reaction kettle in a concurrent flow manner, so that local supersaturation segregation is realized in the solution, and fine seed crystals with high dispersibility are generated; stirring, adding an ammonia water solution, a nickel-cobalt-manganese soluble salt aqueous solution and an alkali solution, controlling the pH value of the system to be 11.4-11.7, and reacting to generate a ternary precursor; aging, separating solid from liquid to obtain precipitate, washing, and drying. The invention generates a large amount of high-dispersion fine seed crystals through local supersaturation segregation of the solution without stirring, and then directly grows the seed crystals to obtain the ternary precursor under the condition of maintaining the pH value at a low value. |
