| titleOfInvention | A kind of preparation method of narrow particle size distribution ternary precursor |
| abstract | The invention provides a preparation method of a ternary precursor with narrow particle size distribution, which comprises the following steps: mixing water, ammonia water and sodium hydroxide solution in a reaction kettle to obtain a mixed solution; a first overflow is arranged on the upper side wall of the reaction kettle port and the second overflow port; the first overflow port is 98 to 102 cm above the second overflow port; the vertical distance between the liquid level of the mixed solution and the second overflow port is 28 to 32 cm; The nickel-cobalt-manganese mixed solution, ammonia water and sodium hydroxide solution are continuously introduced into the mixed solution to carry out the reaction; the material exceeding the second overflow port flows out of the reactor; after the reaction reaches the product particle size D50, the second overflow port is closed, Open the first overflow port, and play the ball after the pH value rises, and make the liquid level between the first and second overflow ports. The orifice flows out to obtain a ternary precursor with a narrow particle size distribution. The process can be continuously produced, and the product particle size distribution is small. |
