METHOD FOR RECYCLING CATHODE ACTIVE MATERIAL AND CATHODE ACTIVE MATERIAL RECYCLED THEREBY

The present invention relates to a method of recycling a positive electrode active material and a recycled positive electrode active material prepared by the same. More particularly, the present invention relates to a method of recycling a positive electrode active material, the method including step A of fragmenting a waste battery including a positive electrode, a separator, and a negative electrode; step B of removing the negative electrode by jetting compressed air onto waste battery scraps; and step C of treating the waste battery scraps from which the negative electrode has been removed with a solvent to remove the separator and obtain positive electrode scraps and a recycled positive electrode active material prepared by the method.According to the present invention, the present invention has an effect of providing a method of recycling a positive electrode active material, the method being capable of greatly improving the rate performance of a battery using a recycled positive electrode active material by removing ceramic transferred from a separator when separating a positive electrode from a waste battery; being capable of achieving eco-friendliness by not using acids, and thus reducing process costs by eliminating the need for neutralization and wastewater treatment processes; being capable of preventing loss of metal elements by recycling a positive electrode active material in an intact state without decomposing the positive electrode active material; being capable of recovering a current collector without dissolving the current collector with an organic solvent; being capable of preventing generation of toxic gases or explosion; and being suitable for mass production by using an easy-to-manage process such as heat treatment or compressed air jet and a recycled positive electrode active material having excellent electrochemical performance, resistance properties, and capacity properties prepared by the method.
