| titleOfInvention | Positive electrode active material for lithium ion secondary batteries, method for producing same, and lithium ion secondary battery |
| abstract | The present invention provides a positive electrode active material which enables the achievement of a lithium ion secondary battery that has a balance between excellent battery capacity and high thermal stability at a high level. A positive electrode active material for lithium ion secondary batteries, which contains lithium nickel manganese composite oxide that is composed of secondary particles, each of which is composed of a plurality of aggregated primary particles. This positive electrode active material for lithium ion secondary batteries is configured such that: the lithium nickel manganese composite oxide has a hexagonal lamellar structure; the substance amount ratio among the metal elements is expressed by Li:Ni:Mn:M:Ti = a:(1 – x – y – z):x:y:z (wherein 0.97 ≤ a ≤ 1.25, 0.05 ≤ x ≤ 0.15, 0 ≤ y ≤ 0.15 and 0.01 ≤ z ≤ 0.05); the ratio of the total of the peak intensities of the strongest lines of titanium compounds to the intensity of the (003) diffraction peak that is the strongest line of the hexagonal lamellar structure is 0.2 or less in XRD measurement of the positive electrode active material; the crystallite diameter of the (003) plane as determined by XRD measurement is from 160 nm to 300 nm (inclusive); and the amount of lithium to be dissolved in water in cases where the positive electrode active material is immersed in water is 0.07% by mass or less relative to the entirety of the positive electrode active material. |
