The electrode assembly includes a positive electrode piece, a negative electrode piece and a first protective layer (500) arranged on the surfaces of the positive electrode piece and the negative electrode piece; and in a projection plane based on a length direction and a width direction of the electrode assembly, an orthographic projection of the first protective layer (500) in the projection plane covers an orthographic projection of a first region (c) of a positive electrode tab (300) in the projection plane. The electrode assembly can take into account the energy of battery on the basis of preventing burrs of tab from piercing a separator.",
