ABSTRACT:
The present invention relates to Li—Ni composite oxide particles for a non-aqueous electrolyte secondary cell which have a large charge/discharge capacity, an excellent packing density and excellent storage performance. The Li—Ni composite oxide particles for a non-aqueous electrolyte secondary cell which have a composition represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?LixNi1-y-zCoyAlz02in-line-formulae description="In-line Formulae" end="tail"?in which 0.9<x<1.3; 0.1<y<0.3; and 0<z<0.3, wherein the composite oxide particles have a rate of change in specific surface area of not more than 10% as measured between before and after applying a pressure of 1 t/cm2thereto, and a sulfate ion content of not more than 1.0%, can be produced by mixing Ni—Co hydroxide particles having a sulfate ion content of not more than 1.0% whose surface is coated with an Al compound having a primary particle diameter of not more than 1 μm, with a lithium compound; and calcining the resulting mixture.
