Abstract
The invention relates to a high-nickel ternary precursor, a lithium-rich positive electrode material and a preparation method, and the preparation method comprises the following steps: adding a nickel manganese solution, a titanium source hydrogen peroxide solution, a precipitant solution and a complexing agent solution into a reaction base solution in a parallel flow manner, and carrying out a co-precipitation reaction to obtain the high-nickel ternary precursor. Ti is added in the coprecipitation process, and the ratio of Li in the obtained lithium-rich positive electrode material is controlled, so that the capacity and the stability of the obtained lithium-rich positive electrode material are improved.
