Abstract:
(EN) The present invention relates to a positive electrode active material for lithium secondary batteries, which contains a lithium metal composite oxide powder represented by general formula (1). The lithium metal composite oxide is configured from primary particles and secondary particles, in each of which a plurality of the primary particles aggregate. This positive electrode active material for lithium secondary batteries has a BET specific surface area of from 1 m2/g to 3 m2/g (inclusive); and the secondary particles have an average breaking strength of from 10 MPa to 100 MPa (inclusive). Li[Lix(Ni(1-y-z-w)CoyMnzMw)1-x]O2 (1) (In the formula, M represents one or more metal elements selected from the group consisting of Fe, Cu, Ti, Mg, Al, W, B, Mo, Nb, Zn, Sn, Zr, Ga and V; -0.1 ≤ x ≤ 0.2; 0 < y ≤ 0.4; 0 < z ≤ 0.4; 0 ≤ w ≤ 0.1; and 0.25 < y + z + w.)
