Abstract
A method for recovering an active metal of a lithium secondary battery according to exemplary embodiments comprises preparing a preliminary cathode active material mixture including a lithium composite oxide and a binder, forming a cathode active material mixture by removing the binder from the preliminary cathode active material mixture through a heat treatment in a fluidized bed reactor, and recovering a lithium precursor from the cathode active material mixture. Accordingly, the active metal of the lithium secondary battery can be recovered with high purity and high efficiency.
