Abstract
This disclosure relates to electrode active materials and batteries. It discloses an electrode active material with an O3-type structure exhibiting high capacity and high coulombic efficiency. The electrode active material of this disclosure comprises a Na-containing transition metal oxide. The Na-containing transition metal oxide has an O3-type structure. The Na-containing transition metal oxide contains Na, Ni, Mn, and O as constituent elements. The X-ray diffraction pattern of the Na-containing transition metal oxide satisfies 0.476. 003 / I 104 <0.554 (where I 003 I is the intensity of the diffraction peak on the (003) plane in the X-ray diffraction pattern. 104 The intensity of the diffraction peak on plane (104) in the X-ray diffraction pattern is given.
