Abstract
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.
Claims3
A nickel hydroxide having a mean primary particle size of 1 to 4.9 μm, a dibutyl phthalate (DBP) absorption amount of 10 to 30 mL/100 g, and a tap density of 2.0 to 3.5 g/cc.
