  "textContent": "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, relating to the technical field of batteries. The electrode assembly includes a positive plate and a negative plate. The electrode assembly includes an abutting region and a non-abutting region at two sides of a thickness central surface thereof. The negative plate includes a plurality of first negative active material layers located in the abutting region, and a plurality of second negative active material layers located in the non-abutting region; the positive plate 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. Therefore, a risk of lithium plating caused by extrusion of an electrolyte when the abutting region abuts against a housing is effectively reduced.",
