  "textContent": "An object of the invention is to provide a method for economically and environmentally friendly collecting an olivine-structured cathode active material from wastes containing the olivine-structured cathode active material that is structurally stable, a recycled cathode active material obtainable therefrom, and a lithium-ion secondary battery in which the recycled cathode active material is applied. To achieve the above object, the method for recycling the olivine-structured cathode active material includes a step (a) of loading a heat treatment object containing an olivine-structured cathode active material into a heat treatment furnace, a step (b) of raising an internal temperature of the heat treatment furnace to a range of about 150°C to about 400°C, a step (c) of maintaining the increased internal temperature to thermally treat the heat treatment object, and a step (d) of discharging first powder produced after the heat treatment is completed. The first powder comprises recycled olivine-structured cathode active material, and the heat treatment object comprises at least a portion of the waste lithium-ion secondary battery or wastes generated during the cathode active material manufacturing process.",
