Electrode, nonaqueous electrolyte battery, and battery pack

A nonaqueous electrolyte battery comprising

• a positive electrode comprising an active material-containing layer,
• a negative electrode comprising a negative electrode active material, and
• a nonaqueous electrolyte,
• wherein the active material-containing layer comprises active material particles and a binder comprising a polymer,
• wherein
• the active material particles comprise a lithium-containing nickel-cobalt-manganese composite oxide represented by LiaNi(1−x−y)CoxMnyMzO2, wherein 0.9≤a≤1.2, 0<x≤0.5, 0<y≤0.5, 0<z≤0.1, x≥y, 0.4≤1-x-y≤0.8, and M is at least one element selected from the group consisting of B, Mg, Al, Si, Ca, Ti, Zn, Zr, Sn, and W, and
• the polymer has a repeating unit derived from vinylidene fluoride, and is configured such that one or more peaks in a nuclear magnetic resonance spectrum with fluorine-19 as a detection nucleus are located in the range of −90 ppm or higher and −88 ppm or lower, and one or more peaks having a peak intensity relative to a reference peak of 5% or more are present in a range of from −94 ppm or higher and −93 ppm or lower.
