Abstract

This invention provides a lithium-nickel-cobalt-manganese composite oxide powder for positive electrodes of lithium secondary batteries having a high volumetric capacity, high safety, and excellent charge/discharge cycle durability. The lithium-nickel-cobalt-manganese composite oxide powder for lithium secondary batteries is represented by the general formula: LipNixCoyMnzMqO2-aFa (where M represents a transition metal element other than Ni, Co and Mn or an alkaline earth metal element, 0.9 ≤ p ≤ 1.1, 0.2 ≤ x ≤ 0.5, 0.1 ≤ y ≤0.4, 0.2 ≤ z ≤0.5, 0 ≤ q ≤0.05, 1.9 ≤ 2-a ≤ 2.1, x+y+z+q = 1, and 0 ≤ a ≤ 0.02). The lithium-nickel-cobalt-manganese composite oxide powder is composed of agglomerate of composite oxide particles having an average particle diameter D50 of 3-15 μm, in which many particles of lithium-nickel-cobalt-manganese composite oxide are gathered together, and has a compressive breaking strength of not less than 50 MPa.
