Abstract text

A positive electrode active material for a non-aqueous electrolyte secondary battery, including a lithium nickel composite oxide, is produced by baking a nickel hydroxide having a mean primary particle size of 1 to 5 μm and a DBP absorption amount of 10 to 30 mL/100 g and a lithium compound in an oxidizing atmosphere. This lithium nickel composite oxide is excellent in packing characteristics and power characteristics (particularly high-rate characteristics), and useful as a positive electrode active material of a non-aqueous electrolyte secondary battery.
