MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202517017930 A) filed by Lg Energy Solution, Ltd., Seoul, Republic of Korea, on Feb. 28, for 'cathode active material, cathode comprising same, and lithium secondary battery.'
Inventor(s) include Kim, Hyeong Il; Park, Sang Min; Kim, Seul Ki; Park, Byung Chun; Lee, Sang Wook; Lho, Eun Sol; Hwang, Jin Tae; and Oh, Su Yeon.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a cathode active material comprising a large-particle-diameter lithium nickel-based transition metal oxide and a small-particle-diameter lithium nickel-based transition metal oxide, wherein the large-particle-diameter lithium nickel-based transition metal oxide is in the form of a secondary particle, which is an aggregate of primary particles, and the small-particle-diameter lithium nickel-based transition metal oxide is in the form of at least one of a single particle composed of one nodule and a pseudo-single particle which is a composite of 30 or fewer nodules, and the P value, defined by a factor relating to the shape of a large-particle diameter particle and a factor relating to the specific surface area of a small-particle diameter particle is 1.00 or larger. The application of the cathode active material to a cathode suppresses the cracking of cathode active material particles, thereby providing a lithium secondary battery which exhibits improved lifespan and output characteristics along with a reduced amount of gas generation."
The patent application was internationally filed on Dec. 22, 2023, under International application No.PCT/KR2023/021399.
