MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517049916 A) filed by Lg Energy Solution, Ltd., Seoul, Republic of Korea, on May 23, for 'positive electrode active material, positive electrode comprising same, and lithium secondary battery.'
Inventor(s) include Kim, Seul Ki; Park, Sang Min; Kim, Hyeong Il; Park, Byung Chun; Lee, Sang Wook; Lho, Eun Sol; Hwang, Jin Tae; and Oh, Su Yeon.
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 positive electrode active material comprising a lithium nickel-based transition metal oxide in the form of secondary particles which are aggregates of primary particles, wherein, with respect to the cross-section at the point of 40% to 60% of the diameter of the secondary particles, the following are satisfied: a) the ratio of the number of primary particles having an aspect ratio of 1.6 or greater in the cross-section is 0.81 or greater; and b) a K value calculated by formula 1 below is 12 to 40. The positive electrode active material as characterized above may reduce particle cracking between cycles and thus may inhibit battery degradation and enhance stability. [Formula 1] K = RAP x NP / AS. Here, RAP is the average aspect ratio of the primary particles, NP is the number of primary particles, and AS is the cross-sectional area of the secondary particles."
The patent application was internationally filed on Dec. 22, 2023, under International application No.PCT/KR2023/021495.
