Title:
METHOD FOR ISOLATING TRANSITION METAL AND LI FROM COMPOUND INCLUDING LI AND TRANSITION METAL
Document Type and Number:
WIPO Patent Application WO/2024/095737
Kind Code:
A1
Abstract:
The disclosed method for isolating a transition metal and Li comprises a step in which a compound including Li and the transition metal is reacted with a carboxylic acid in water to obtain a slurry comprising both a first solution, which contains Li ions, and a precipitate including a transition metal carboxylate and a step in which the precipitate is separated from the first solution, the transition metal being at least one metal selected from the group consisting of Ni, Co, Mn, Ti, Fe, and Cu.
