This utility model relates to an electrode assembly, a battery cell, a battery, and an electric device. An electrode assembly includes an anode electrode plate and a cathode electrode plate. At least one side of the anode current collector is coated with an anode active substance layer. At least one side of the cathode current collector is coated with a cathode active substance layer and an additional layer. In a plane perpendicular to the stacking direction of the anode electrode plate and the cathode electrode plate, a projection of the anode active substance layer covers a projection of the cathode active substance layer and partially covers a projection of the additional layer. A battery includes the battery cells. An electric device includes the battery cells or the foregoing battery. The electrode assembly, battery cell, battery, and electric device can mitigate or reduce electrode plate cracking.
