| titleOfInvention | Positive electrode active material for non-aqueous electrolyte secondary battery, lithium transition metal composite oxide, method for producing positive electrode active material for non-aqueous electrolyte secondary battery, and non-aqueous electrolyte secondary battery |
| abstract | Provided is a positive electrode active material for producing a nonaqueous electrolyte secondary battery having a large discharge capacity, excellent initial charge / discharge efficiency, and high rate discharge characteristics, and a method for producing the same, and used for the positive electrode active material. Provided is a novel lithium transition metal composite oxide. In a positive electrode active material for a non-aqueous electrolyte secondary battery including a lithium transition metal composite oxide, the lithium transition metal composite oxide includes Li, and a transition metal element (general formula Li) containing Co, Ni, and Mn. a Co x Ni y Mn z O 2 , a + x + y + z = 2), the molar ratio Li / Me (a / (x + y + z)) of Li to the total transition metal element Me is 1.25 to 1.40, The molar ratio Co / Me (x / (x + y + z)) is 0.020 to 0.230, the molar ratio Mn / Me (z / (x + y + z)) is 0.625 to 0.719, and the BET ratio The surface area is 0.88 m 2 / g or more, and the tap density is 1.25 g / cc or more. And a step of producing a precursor by co-precipitation of a compound containing Co, Ni and Mn in the solution, and a step of mixing and firing the precursor and the lithium compound. It is a manufacturing method of the positive electrode active material for secondary batteries, Comprising: pH in the process of manufacturing a precursor is 8.5-9.4, and a calcination temperature is 800-940 degreeC, It is characterized by the above-mentioned.
