TECHNICAL FIELD

[0001] The present application relates to the technical field of ternary precursor powder washing, in particular to a ternary precursor powder washing device. BACKGROUND

[0002] The ternary precursor powder is a composite hydroxide composed of nickel (Ni), cobalt (Co) and manganese (Mn), which is usually used for the preparation of lithium ion battery positive electrode materials. It is synthesized by co-precipitation method, and its performance directly affects the energy density, cycle life and safety of the final lithium battery. In the synthesis process of the ternary precursor, some residual impurities may be introduced. If not washed thoroughly, it will have a negative impact on the quality of the subsequent positive electrode material and the performance of the battery. Therefore, it is necessary to remove these impurities through multiple washing to ensure the high purity and uniformity of the powder, and thus improve the electrochemical performance of the positive electrode material.

[0003] In the washing process of the ternary precursor, deionized water or ultrapure water is commonly used as the washing medium to ensure the removal effect of impurity ions and prevent secondary pollution. The number of washing depends on the impurity content of the precursor powder and the quality requirements of the final material, and usually requires 3-5 times of washing to ensure that the impurity concentration is reduced to the qualified range. Currently, the ternary precursor powder is usually washed in a vertically placed cylinder. When changing water each time, the washing liquid in the cylinder is discharged through the discharge pipe.
