Abstract
There is provided a novel lithium nickel complex oxide represented by the general formula: EQU Li.sub.y-x1 Ni.sub.1-x2 M.sub.x O.sub.2 wherein M represents one selected from the group consisting of Al, Fe, Co, Mn and Mg, x=x.sub.1 +x.sub.2, O<x.sub.1 .ltoreq.0.2, O<x.sub.2 .ltoreq.0.5, 0<x.ltoreq.0.5, and 0.9.ltoreq.y.ltoreq.1.3, and wherein the crystals have been sufficiently developed and are highly purified, and a positive electrode active material for a secondary battery whose stability of high discharge capacity is excellent.
