| abstract | A positive electrode active material having a porous structure and a lithium nickel manganese cobalt-containing composite oxide with a high nickel ratio, which has improved durability and improved output characteristics. SOLUTION: Crystallization is divided into nucleation and particle growth, a first raw material aqueous solution is used for the first stage in a non-oxidizing atmosphere, and a second stage is an oxidizing atmosphere using a low nickel ratio second raw material aqueous solution. The third step is a first aqueous solution non-oxidizing atmosphere, the fourth step is a second aqueous solution oxidizing atmosphere, the fifth step is a first aqueous solution non-oxidizing atmosphere, and the sixth step is a second aqueous solution oxidizing atmosphere. The composite hydroxide is formed into a multilayer structure. The center portion 1, the high-density layer 3, and the outer shell layer 5 have a high nickel ratio, and the first to third low-density layers 2, 4 and 6 have a low nickel ratio, and a positive electrode active material using this composite hydroxide as a precursor The substance has an outer shell part, an agglomerate part electrically connected to the outer shell part, and a space part existing dispersedly between the agglomerates, and the primary particles have a surface layer part in which the nickel ratio is graded.
