An electrode assembly, a battery cell, a battery, and an electrical device are provided. The electrode assembly includes a negative electrode plate, a separator, and a positive electrode plate. The separator is disposed between the negative electrode plate and the positive electrode plate. The positive electrode plate includes a positive electrode active material layer, and the separator has an extension area extending out of the positive electrode active material layer in a first direction. A barrier portion is disposed on at least one side of the extension area, and the barrier portion is used for blocking a gap between the separator and the positive electrode plate or a gap between the separator and the negative electrode plate.
