Abstract
In a method for recovering active metals from a lithium secondary battery according to exemplary embodiments, a cathode active material mixture including a lithium composite oxide may be reacted with a reducing reaction gas under a pressurized condition and washed with water. In this case, a large amount of the cathode active material mixture may be treated within a shortened process time, and the active metal may be recovered with high yield and high efficiency.
