Abstract
A positive electrode active material contains a lithium composite oxide and a covering material. The lithium composite oxide has a crystal structure that belongs to space group Fd-3m. The ration I(111)/I(400) of a first integrated intensity I(111) of a first peak corresponding to a (111) plane to a second integrated intensity I(400) of a second peak corresponding to a (400) plane in an XRD pattern of the lithium composite oxide satisfies 0.05≤I(111)/I(400)≤0.90. The covering material has an electron conductivity of 106 S/m or less.
