    Abstract: The present application provides an electrode assembly, a batter cell, a battery, an electric apparatus, and a manufacturing method and device of the electrode assembly. A negative plate of the electrode assembly includes a plurality of first negative active material layers located in an abutting region, and a plurality of second negative active material layers located in a non-abutting region; a positive plate of the electrode assembly includes a plurality of first positive active material layers located in the abutting region, and a plurality of second positive active material layers located in the non-abutting region. An active material capacity per unit area of the first negative active material layer is greater than that of the second negative active material layer; and/or an active material capacity per unit area of the first positive active material layer is less than that of the second positive active material layer.
