摘要： An electrode assembly includes an electrode stack having a first electrode, a first separation layer, a second electrode and a second separation layer consecutively stacked, the electrode stack being wound around a winding axis in a winding direction, and a first electrode tab electrically connected to the first electrode, the first electrode tab protruding in an axial direction away from a first end of the first electrode. The second electrode includes a second electrode uncoated portion where an active material is not coated, the second uncoated portion being exposed at a second end of the second electrode in the axial direction, the second uncoated portion being configured to be a second electrode tab. A battery cell including the electrode assembly is also provided.
