Abstract: The present invention relates to a recycled cathode active material, a method of recycling a cathode active material, and a secondary battery including the recycled cathode active material. Specifically, the method of recycling a cathode active material according to the present invention includes step (a) of separating a current collector from a cathode active material layer and recovering a cathode active material in the cathode active material layer by thermally decomposing a binder and a conductive material in the cathode active material layer by heat-treating a waste cathode including the current collector and the cathode active material layer formed on the current collector; and step (b) of adding a lithium precursor and a Co-containing coating agent to the recovered cathode active material and performing annealing.
According to the present invention, the present invention has an effect of providing a method of recycling a cathode active material. According to the method of the present invention, by heat-treating a waste cathode, a cathode active material is recovered. Then, a lithium precursor and a Co-containing coating agent are added to the recovered cathode active material, and annealing is performed. Through this process, process advantages may be obtained, and recovery of a crystal structure and recovery of a surface coating layer may be achieved simultaneously. As a result, the initial capacity and resistance characteristics of a secondary battery may be improved. In addition, eco-friendliness may be secured by not using acids in recovery and recycling processes, process cost may be reduced because neutralization and wastewater treatment are not required accordingly, no metal element is discarded by recycling a cathode active material in an intact state without disassembling the cathode active material, the risk of toxic gas generation or explosion may be excluded by not using an organic solvent, and economic feasibility and productivity may be greatly improved by omitting a washing process.
