The present invention relates to a method for regenerating a cathode active material and a regenerated cathode active material regenerated thereby and, more specifically, to a method for regenerating a cathode active material, comprising the steps of: detaching a cathode active material from a waste cathode through heat treatment at a predetermined temperature; and milling the recovered cathode active material. Accordingly, the regenerated cathode active material may have a reduced specific surface area and reduced impurities derived from a coating agent such as carbon, and excellent electrical conductivity, and may provide excellent coating properties by lowering the viscosity of an electrode slurry comprising the regenerated cathode active material. When applied to a secondary battery, the cathode active material provides excellent battery characteristics, does not use a strong acid or an organic solvent and is therefore eco-friendly, and greatly improves economic feasibility and productivity since, through a simple process, the cathode active material can be regenerated as it is without decomposition of the cathode active material.
