Inventors include Su, Meihua; Niu, Cong; Song, Mengxiao; Li, Zhenghua; Cho, Minsu; Ryu, Jihoon; and Kim, Dongkyu.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Disclosed are a quenching solution, a method for manufacturing a surface-stabilized Li-rich manganese-based positive electrode material, and a secondary battery. The quenching solution contains a solvent, a lithium hydroxide or lithium salt, a reducing agent, and a phosphate, and the Li-rich manganese-based positive electrode material is treated by a quenching method in the quenching solution, thereby improving the initial coulombic efficiency and cyclic stability of the battery and alleviating voltage decay.
