Document Type and Number:
WIPO Patent Application WO/2018/223931
Kind Code:
A1
Abstract:
A method for preparing positive electrode ternary precursor powder. The positive electrode ternary precursor powder contains three elements, i.e., nickel, cobalt and manganese. The method comprises: carrying out acid dissolution on nickel cobalt hydroxide so as to obtain a solution after acid solving; carrying out impurity removal treatment on the solution after acid solving so as to obtain a solution after impurity removal; adjusting the proportions of nickel, cobalt, and manganese in the solution after impurity removal so as to obtain a former solution; and using the former solution to prepare the positive electrode ternary precursor powder.
