Document Type and Number:
WIPO Patent Application WO/2024/040901
Kind Code:
A1
Abstract:
Disclosed in the present invention is a preparation method for crystal-transformed aluminum-doped cobalt carbonate, comprising the following steps: (1) preparing a mixed metal solution from cobalt salts and aluminum salts, and preparing a first ammonium bicarbonate solution, a second ammonium bicarbonate solution and a third ammonium bicarbonate solution; (2) adding the mixed metal solution and the second ammonium bicarbonate solution together into the first ammonium bicarbonate solution for mixing to undergo a reaction, and controlling the reaction temperature to be 40-45°C until a crystal-transformed aluminum-doped cobalt carbonate seed crystal having a specific surface area of 0.3-0.6 cm2/g is generated; and (3) adding the mixed metal solution and the third ammonium bicarbonate solution together into the solution containing the crystal-transformed aluminum-doped cobalt carbonate seed crystal obtained in step (2) for mixing to undergo a reaction until the particle size of the crystal-transformed aluminum-doped cobalt carbonate seed crystal grows to 16.0-19.0 μm, performing solid-liquid separation, and washing and drying the obtained solid to obtain the crystal-transformed aluminum-doped cobalt carbonate. The crystal-transformed aluminum-doped cobalt carbonate prepared by the preparation method for crystal-transformed aluminum-doped cobalt carbonate has a good aluminum doping effect.
