Abstract
A non-aqueous electrolyte secondary battery uses as its positive electrode active material a mixture of a first lithium-containing transition metal oxide containing nickel and manganese as transition metals and having a crystal structure belonging to the space group R3m and a second lithium-containing transition metal oxide containing nickel, cobalt, and manganese as transition metals and having a crystal structure belonging to the space group R3m, or a mixture of the first lithium-containing transition metal oxide and a lithium cobalt oxide. The first lithium-containing transition metal oxide is LiNiMnOwherein 1≦a≦1.5, 0.5≦x+y≦1, 0<x<1, and 0<y<1. The second lithium-containing transition metal oxide is LiNiMnCoOwherein 1≦b≦1.5, 0.5≦p+q+r≦1, 0<p<1, 0<q<1, and 0<r<1.
