Abstract

A positive electrode active material in a form of a single particle is configured so that after a positive electrode, which includes a positive electrode active material layer containing 80 wt % or more of the positive electrode active material based on a total weight of the positive electrode active material layer, is rolled, a density of the positive electrode active material layer after the rolling is 2.7 g/cm3 or more. When the positive electrode active material layer is analyzed by XRD (X-ray diffraction), a ratio of an area of a (003) peak to an area of all peaks identified in a 2θ range of 10° to 90° satisfies 30% or more. Also provided is a positive electrode including the same. The positive electrode active material is capable of achieving a battery with improved initial resistance characteristics and life characteristics.
