摘要:PROBLEM TO BE SOLVED: To provide a positive electrode and a nonaqueous electrolyte battery having a high energy density and suffering only a small resistance rise in charge-discharge cycles, and a battery pack including the nonaqueous electrolyte battery.SOLUTION: The positive electrode comprises a positive electrode active material layer, and a positive electrode collector on which the positive electrode active material layer is formed. The positive electrode active material layer contains 73-95 wt.% of a positive electrode active material containing LiNiCoMnMO, where 0.9<x≤1.25, 0<a≤0.4, 0<b≤0.45, 0≤c≤0.1, and M represents at least one kind of element selected from Mg, Al, Si, Ti, Zn, Zr, Ca, and Sn, and/or LiNiCoMO, where 0.9<x≤1.25, 0<a≤0.4, 0≤c≤0.1, and M represents at least one kind of element selected from Mg, Al, Si, Ti, Zn, Zr, Ca, and Sn; 3-20 wt.% of a carbonaceous material as a conductive agent; and 2-7 wt.% of a binder.
