Zusammenfassung:	An electrode assembly and a secondary battery having the same are disclosed. The electrode assembly includes a positive electrode plate, a negative electrode plate, and a separator. The positive electrode plate includes a positive electrode active material and a positive electrode tab. The negative electrode plate includes a negative electrode active material and a negative electrode tab. The separator is disposed between the positive electrode plate and the negative electrode plate. A negative electrode uncoated portion is disposed on the negative electrode plate corresponding to a position of the positive electrode tab. A positive electrode uncoated portion is disposed on the positive electrode plate corresponding to a position of the negative electrode tab. A similar effect is achieved by using a cutout portion rather than an uncoated portion.
