"textContent": "An example of a positive electrode active material according to one embodiment includes a lithium transition metal composite oxide that contains at least 80 mol % of Ni and Mn with respect to the total molar amount of metal elements other than Li. The lithium transition metal composite oxide is composed of one primary particle, or particles composed of 2 to 100 primary particles, and has a D50 of 0.6 μm to 4.0 μm, and a crystallite size of 370 Å to 1,500 Å. On a particle surface of the composite oxide, at least one selected from among a pyrophosphoric acid and a phosphate salt is present in an amount of 0.1 mol % to 5.0 mol %.",
