The electrode assembly includes a positive electrode plate, a separator, and a negative electrode plate, where the negative electrode plate includes a negative electrode current collector and a negative electrode active substance layer, the negative electrode plate further includes a lithium metal layer, the lithium metal layer is formed by a plurality of regular or irregular strip-shaped lithium-rich regions, and the plurality of lithium-rich regions present a discontinuous pattern of spaced distribution in a length direction of the negative electrode plate. The electrode assembly further satisfies that: negative electrode capacity per unit area/positive electrode capacity per unit area=1.2 to 2.1 and negative electrode capacity per unit area/(positive electrode capacity per unit area+capacity of the lithium metal layer on the surface of the negative electrode active substance layer per unit area×80%)≥1.10.",
