Proposed are a method of preparing a positive electrode active material for a secondary battery using a waste battery and a positive electrode active material for a secondary battery prepared thereby. The method includes removing a current collector from a waste positive electrode of a waste battery to recover a solidified waste positive electrode active material, performing a first heat treatment on the recovered waste positive electrode active material to remove a binder and a conductive additive while forming rock-salt structure single crystals by thermal instability, and performing a second heat treatment at a temperature higher than a first heat treatment temperature to obtain a regenerated positive electrode active material, after performing the first heat treatment. Accordingly, the preparation process is simplified by omitting leachate treatment and directly recycling the waste positive electrode active material to regenerate the positive electrode active material, reducing manufacturing costs and significantly improving economic feasibility.
