Abstract
In a method for recovering an active metal of a lithium secondary battery, positive electrode active material particles including a lithium-transition metal oxide is prepared. The positive active material particles are treated by reduction. The reduction-treated positive active particles are subjected to ultrasonic dispersion and hydration. The hydrated transition metal slurry is recovered. The recovery rate of lithium and transition metal can be increased by disaggregation through ultrasonic dispersion.
