摘要
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: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒLi x Ni 1-y-z Co y Al z O 2 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/cm 2 thereto, 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.
