Abstract: A jelly-roll type electrode assembly includes a first separator, a second separator, a negative electrode, and a positive electrode. The first separator and second separator are positioned adjacent each other in a separator overlapping portion and extend with at least three layers in a first direction toward a core of the electrode assembly between an inner surface of the positive electrode and an outer surface of the negative electrode. An adhesive tape is located in at least one of a location between the outer surface of the positive electrode and an inner surface of the first separator, and a location between an outer surface of the negative electrode and the inner surface of the first separator.
