Abstract
A cathode active material for a non-aqueous electrolyte secondary battery satisfies conditions (1) to (5): (1) the cathode active material contains Li, Mn, and Ni and has a spinel structure; (2) a molar ratio of Ni to Mn is in a range from 0.10 to 0.43; (3) a molar ratio of Li to Mn is in a range from 0.70 to 1.80; (4) the cathode active material has a peak in a range of 2θ=19.7 to 22.5° in an X-ray diffraction pattern; and (5) the cathode active material has at least one peak in a voltage range of voltage Vand at least two peaks in a voltage range of voltage Vin an initial dQ/dV curve of a discharge measured when a half cell is prepared using the cathode active material,
