ABSTRACT:
A non-aqueous lithium ion secondary battery is composed of a positive electrode, a negative electrode, and non-aqueous electrolyte. In the battery, the positive electrode is composed of an positive electrode active material of the formula: Li.sub.x Ni.sub.1-y M.sub.y O.sub.2-z X.sub.a in which M is at least one element such as Mg, Ca, B, Al, Ga, In, Si, Sn, Ge, Pb and at least one transition metal element; X is a halogen atom; x, y, z and a are numbers satisfying the conditions of 0.2<x.ltoreq.1.2, 0<y.ltoreq.0.5, 0.ltoreq.z.ltoreq.1 and 0.ltoreq.a.ltoreq.2z, and the negative electrode is composed of amorphous metal complex oxide or a combination of crystalline and/or amorphous metal complex oxide and carbonaceous material.
