<p>An active substance of positive electrode that enables obtaining a battery exhibiting high energy density and excellent high-rate discharge performance and, even when high-temperature charging is effected, suffering less deterioration of battery performance; and a nonaqueous electrolyte battery containing the same. The positive electrode active substance is composed at least of lithium (Li), manganese (Mn), nickel (Ni), cobalt (Co) and oxygen (O), and contains a double oxide of the chemical composition formula: LiaMnbNicCodOe (wherein 0<a≤1.3, |b-c|≤0.05, 0.6≤d<1, 1.7≤e≤2.3, and b+c+d=1). The nonaqueous electrolyte battery comprises a positive electrode containing the above active substance, a negative electrode and a nonaqueous electrolyte.</p> |
