Inventors include Kim, Hyeong Il; Lho, Eun Sol; Hwang, Jin Tae; Oh, Su Yeon; and Lee, Seok Jin.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a positive electrode active material comprising a single-particle lithium nickel-based oxide expressed by [Chemical formula 1], and a coating layer disposed on the surface of the single-particle lithium nickel-based oxide, wherein the ratio RPI2/RPI1 of RPI2 defined by Formula 2 below against RPI1 defined by Formula 1 below is 1-1.3. [Chemica formula 1] Lix[NiaCobM1cM2d]O2 In Chemical formula 1 above, M1 is Mn, Al, or a combination thereof, M2 comprises at least one selected from the group consisting of Ti, Mg, Zr, Y, Ba, Ca, Sr, W, Ta, Nb, and Mo, and 0.9=x=1.1, 0.8=a1, 0b0.2, 0c0.2, 0=d0.1. [Formula 1] RPI1=I2 /I1 [Formula 2] RPI2=I3 /I1 In Formula 1 and Formula 2 above, I1, I2 , and I3 are values obtained by manufacturing an electrode comprising the positive electrode active material and then measuring the X-ray diffraction pattern; I1 is the minimum value of peak intensity appearing in the region in which 2?=37°-38° in the X-ray diffraction pattern; I2 is the average value of peak intensities appearing in the region in which 2?=37.3°- 37.5°; and I3 is the average value of peak intensities appearing in the region in which 2?=37.0°- 37.2°.
