Document Type and Number:
WIPO Patent Application WO/2023/246724
Kind Code:
A8
Abstract:
Disclosed are a cathode material precursor, a cathode material, a method for preparing same, and use thereof. The method for preparing the cathode material precursor comprises the following steps: mixing a salt solution of a transition metal and a precipitant solution under a supergravity condition for a coprecipitation reaction to obtain a precipitate, wherein the transition metal is selected from one or more of nickel, iron, manganese, copper, aluminum, cerium, cobalt, zinc, tin, and titanium. The preparation method of the present invention features low energy consumption, low time consumption, and continuous and controllable reaction and enables large-scale, rapid, and high-quality production of the precursor. The precursor prepared according to the present invention is good in morphology, particle size, and consistency, and the cathode material prepared from the precursor has excellent electrochemical performance.
