MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058519 A) filed by Lg Energy Solution, Ltd., Seoul, Republic of Korea, on June 18, for 'positive electrode active material, positive electrode comprising the same, and lithium secondary battery.'
Inventor(s) include Shin, Donghwa; Lee, Boram; and Park, Sojung.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a cathode active material comprising an overlithiated manganese-based transition metal oxide, comprising an overlithiated manganese-based transition metal oxide, and having a density (P) of 42-50 as derived by equation 1, wherein the cathode active material maximizes intermolecular density by means of optimization of a ratio between lattice parameters of a unit cell and a rolling density under weak pressure, and accordingly, may provide a cathode having optimal density after electrode coating and electrode rolling. In equation 1, Vunit-cell is the volume of a unit cell (A3) which is derived through equation 2, and d400 is the rolling density (g/cm3) when being rolled at 400 kgf. In equation 2, a and c are crystal lattice parameters (A) derived from XRD measurement of the cathode active material."
The patent application was internationally filed on Dec. 21, 2023, under International application No.PCT/KR2023/021251.
