Title:
FLUIDIZED BED REACTOR AND METHOD FOR RECOVERING ACTIVE METAL OF LITHIUM SECONDARY BATTERY BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/058374
Kind Code:
A1
Abstract:
A method for recovering an active metal of a lithium secondary battery being capable of supplying a positive electrode active material mixture to a fluidized bed reactor including a reactor body. It is possible to form a fluidized bed containing a preliminary precursor mixture within the reactor body by introducing a reaction gas from the bottom of the fluidized bed reactor. After cooling a fluidized bed portion that has entered the top of the fluidized bed reactor and lowering the fluidized bed portion into the reactor body, it is possible to recover a lithium precursor from the preliminary precursor mixture. Accordingly, the terminal velocity of a preliminary precursor is reduced, and it is possible to prevent loss due to scattering even if the particle size of the preliminary precursor is small.
