Abstract
A positive electrode active material contains a lithium composite oxide and a covering material. The lithium composite oxide contains at least one element selected from the group consisting of fluorine, chlorine, nitrogen, and sulfur. The lithium composite oxide has a crystal structure that belongs to space group C2/m. The ratio I/Iof a first integrated intensity Iof a first peak corresponding to a (003) plane to a second integrated intensity Iof a second peak corresponding to a (104) plane in an XRD pattern of the lithium composite oxide satisfies 0.05≤I/I≤0.90. The covering material has an electron conductivity of 10S/m or less.
