PURPOSE: A manufacturing method of a positive electrode active material from a positive electrode plate scrap is provided to consist of simple steps, to separate a positive electrode active material with high purity by separating the positive electrode active material through a physical method, and to facilitate post process which is a separation refilling process. CONSTITUTION: A manufacturing method of a positive electrode active material from a positive electrode plate scrap comprises: a cutting step(S100) cutting a current collector coated with a positive electrode active material to moderate size; a heat treatment step(S200) heat-treating the cut current collector in low temperatures; a cooling step cooling the heat-treated current collector in the air; a vibration and separation step(S400) detaching and separating the active material from a surface of the current collector by using a concussor.
