摘要:
In a method of recovering an active metal of a lithium secondary battery, a cathode active material mixture obtained from a used cathode of a lithium secondary battery is prepared. The cathode active material mixture is reacted in a fluidized bed reactor to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. Yield and selectivity of a lithium precursor can be improved using the fluidized bed reactor.
