Abstract
A positive-electrode active material contains a lithium composite oxide containing at least one selected from the group consisting of fluorine, chlorine, nitrogen, sulfur, bromine, and iodine. The crystal structure of the lithium composite oxide belongs to the space group R-3m. The integrated intensity ratio I(003)/I(104) of a peak intensity I(003) on the (003) plane to a peak intensity I(104) on the (104) plane in an XRD pattern of the lithium composite oxide satisfies 0.62≤I(003)/I(104)≤0.90.
