| titleOfInvention | Nickel-cobalt-aluminum ternary precursor, preparation method thereof, positive electrode material and method thereof |
| abstract | The invention discloses a nickel-cobalt-aluminum ternary precursor, a preparation method thereof, a positive electrode material and a method thereof, wherein soluble salts of Ni and Co are dissolved in ammonia water to form an ammonia complex ion solution of Ni and Co as a complexing agent Solution, in the aluminum salt solution, add complexing agent to form Al complex ion solution as aluminum source solution, Ni, Co soluble salt solution, precipitant solution and complexing agent solution and aluminum source solution flow into the reactor in parallel, control The reaction pH value and reaction temperature, the reaction time is at least 10h, the slurry obtained by the reaction is separated from the solid and liquid, and the obtained solid is washed and dried to obtain the nickel cobalt aluminum hydroxide precursor. The mixture of the precursor and the lithium salt is subjected to high-temperature heat treatment in an air or oxygen atmosphere to obtain a nickel-cobalt-aluminum ternary positive electrode material. It can effectively improve the mixing uniformity of the three elements of Ni, Co and Al, and improve the tap density of the precursor material and the sphericity of the particles. |
