Positive Electrode Active Material, Method For Regenerating Positive Electrode Active Material, And Secondary Battery

Abstract: The present invention relates to a positive electrode active material, a method for regenerating the positive electrode active material, and a secondary battery. According to the present invention, there is the effect of providing a positive electrode active material, a method for regenerating the positive electrode active material, a secondary battery, and the like, in which, by detaching and recovering a positive electrode active material from a waste positive electrode, applying a coating agent thereonto, and controlling firing conditions and the like of the positive electrode active material on which the coating agent is applied, a structure similar to the crystal structure of a fresh positive electrode active material can be exhibited while reducing a region where a compound having an olivine structure is mixed in a carbon coating layer on the surface of the positive electrode active material, thus providing satisfactory battery characteristics.
