Abstract
An object of the present invention is to provide a positive electrode active material for a sodium ion secondary battery which has a large discharge capacity and a high average operating voltage in the sodium ion secondary battery to be obtained. The positive electrode active material for a sodium ion secondary battery according to the present invention is a positive electrode active material for a sodium ion secondary battery, the material including a composite oxide represented by particular Formula (1), a crystalline structure of the composite oxide belongs to a space group R-3m, and in a diffraction chart obtained by performing X-ray diffraction measurement, a ratio of a peak strength of 003 reflection of the composite oxide to a peak strength of 104 reflection of the composite oxide is not less than 1.00.
