| titleOfInvention | Positive electrode active material for nonaqueous electrolyte secondary batteries, nonaqueous electrolyte secondary battery, and method for producing positive electrode active material for nonaqueous electrolyte secondary batteries |
| abstract | The purpose of the present invention is to provide a positive electrode active material which enables the achievement of a nonaqueous electrolyte secondary battery that has achieved a good balance between high thermal stability and excellent battery characteristics at high levels, while suppressing decrease in the tap density. A positive electrode active material for nonaqueous electrolyte secondary batteries, that contains a lithium-nickel-manganese composite oxide which contains lithium (Li), nickel (Ni), manganese (Mn), zirconium (Zr) and optionally an element M, and which is configured of secondary particles, each one of said secondary particles being composed of a plurality of aggregated primary particles. This positive electrode active material for nonaqueous electrolyte secondary batteries is characterized in that: the substance quantity ratio (molar ratio) of the elements of the lithium-nickel-manganese composite oxide is represented by Li:Ni:Mn:M:Zr = d:(1 - a - b - c):a:b:c (wherein a satisfies 0.05 ≤ a ≤ 0.60; b satisfies 0 ≤ b ≤ 0.60; c satisfies 0.0003 ≤ c ≤ 0.06; d satisfies 0.95 ≤ d ≤ 1.20; (1 - a - b - c) satisfies 0.30 ≤ (1 - a - b - c) ≤ 0.95; and M represents at least one element selected from among Co, W, Mo, V, Mg, Ca, Al, Ti, Cr, Nb and Ta); at least some of the zirconium in the lithium-nickel-manganese composite oxide is solid-solved in the primary particles; the variation index of the particle diameters, namely (D90 - D10)/Mv that is calculated from the volume average particle diameter (Mv), and D90 and D10 in the particle size distribution of the secondary particles as determined by a laser diffraction/scattering method is from 0.80 to 1.20 (inclusive); and the Li occupancy as determined by Rietveld analysis is within the range of from 94% to 97% (inclusive). |
