MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202517104841 A) filed by Lg Energy Solution, Ltd., Seoul, Republic of Korea, on Oct. 30, 2025, for 'method for regenerating cathode active material, and regenerated cathode active material prepared thereby.'
Inventor(s) include Seo, Yongsik; Park, Gwangseon; Choi, Jeong Mi; Park, Se Ho; Lee, Jeongbae; and Kim, Yeon Jun.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a method for regenerating a cathode active material, and a regenerated cathode active material prepared thereby. The method comprises the steps of: a) heat-treating, at 300-650 C, a waste cathode, which has a cathode active material layer formed on a current collector, so as to thermally decompose a binder and a conductive material in the cathode active material layer, thereby separating the current collector from the cathode active material layer and recovering a cathode active material in the cathode active material layer; b) heat-treating the recovered cathode active material again at 350-700 C for 1-10 hours; c) adding a lithium precursor to the reheated cathode active material and annealing same at 500-1,000 C; d) washing the annealed cathode active material with a washing solution; and e) surface-coating the washed cathode active material with a coating agent."
