Inventor(s) include Kim, Jong Woo; Yoo, Tae Gu; Park, Jin Bum; Yoo, Seung Su; Jo, Chi Ho; Kim, Su Hwan; and Park, Byung Chun.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "A positive electrode active material according to the present invention is a positive electrode active material comprising: a lithium composite transition metal oxide in the form of a single particle consisting of one single nodule or a pseudo-single particle which is a composite of 40 or fewer nodules, wherein the content of nickel in the total metal excluding lithium is 50 mol% to 80 mol%; and a tungsten-containing coating layer formed on the surface of the lithium composite transition metal oxide. The ratio (Li/W) of the number of moles of lithium to the number of moles of tungsten satisfies 30-45, the number of moles being measured by analyzing the positive electrode active material with inductively coupled plasma optical emission spectroscopy (ICP-OES) after pretreating the positive electrode active material under a condition of immersing the positive electrode active material in deionized water at 25? for 1 hour."
