| titleOfInvention | Positive electrode active material for lithium-ion secondary battery, method for producing the same, and lithium-ion secondary battery |
| abstract | PROBLEM TO BE SOLVED: To provide a positive electrode active material for a lithium ion secondary battery, which has a high capacity, a high output, a low elution alkali amount and a high thermal stability required for the safety of the secondary battery. SOLUTION: A plurality of primary particles include secondary particles aggregated with each other, and the primary particles are represented by the formula (1) of the general formula: Li 1+t Ni x Mn y M z W S O 2+β (M is Co, Al, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and at least one element selected from Fe.) and a lithium nickel manganese tungsten composite oxide particle having a hexagonal layered structure. Including, at least a portion of the tungsten in the composite oxide, a solid solution in the secondary particles, and at least a portion of the primary particles between the manganese-enriched core portion and the nickel-enriched surface layer portion, A positive electrode active material for a lithium ion secondary battery, which has a particle structure having a tungsten region with a concentration higher than the average W concentration of the positive electrode active material.
