Abstract
A method for reusing a positive electrode active material includes dry-milling a positive electrode scrap comprising an active material layer on a current collector to convert the active material layer into a powdered state and to separate the active material layer from the current collector. The active material layer is a lithium composite transition metal oxide positive material active material layer. The method further includes adding a lithium precursor to a the active material layer. The method further includes thermally treating the active material layer in the powdered state to collect an active material. The method further includes obtaining a reusable active material by washing the collected active material with a basic lithium compound aqueous solution and drying the collected active material.
