The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a cathode active material comprising: a lithium composite transition metal oxide in the form of a single particle consisting of one nodule or a pseudo-single particle which is a composite of 30 or fewer nodules; and a coating layer including a first coating layer formed on the surface of the lithium composite transition metal oxide and a second coating layer formed on the surface of the first coating layer, wherein the lithium composite transition metal oxide has a roundness of 0.50-0.68 as defined by equation 1, and the second coating layer includes boron, wherein the boron is included in a weight of 300 ppm to 2400 ppm, based on the total weight of the cathode active material. [Equation 1] Roundness = (4×Area) / (p×R2) In equation 1, R indicates the length of a long axis passing through the center of the lithium composite transition metal oxide, and Area indicates the actual area of the lithium composite transition metal oxide.
