Abstract
An electrode includes an active material-containing layer that contains active material particles and a binder containing a polymer. The active material particles contain a lithium-containing nickel-cobalt-manganese composite oxide represented by LiNiCoMnMOwhere 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 B, Mg, Al, Si, Ca, Ti, Zn, Zr, Sn, and W. The polymer has a repeating unit derived from vinylidene fluoride and 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.
