Abstract: A positive electrode active material includes lithium-containing cobalt oxide particles. The lithium-containing cobalt oxide particles include an Mn element and an Ni element. On the basis that the molar content of metal elements except a lithium element in the lithium-containing cobalt oxide particles is 100%, the content of the Mn element is A %, and the content of the Ni element is B %, where 0.1≤A+B
