Original Abstract Submitted
a secondary battery includes an electrode assembly in which a negative electrode plate, a separator, and a positive electrode plate are laminated and wound; and an exterior material accommodating the electrode assembly, wherein the positive electrode plate includes a conductive base material layer having first and second surfaces, the second surface being an opposite surface of the first surface, a first functional layer on the first surface of the conductive base material layer, a first electrically active material layer on the first functional layer, a first insulating layer on the first surface of the conductive base material layer, the first insulating layer being spaced apart from the first functional layer and the first electrically active material layer, and a first lamination tape covering a part of the first functional layer, the first electrically active material layer, the first insulating layer, and the first surface of the conductive base material layer.
