Abstract
A jelly-roll type battery unit includes a first electrode plate having a first electrode current collector with a first electrode tab, and a first electrode active material layer on a surface of the first electrode current collector; a second electrode plate having a second electrode current collector with a second electrode tab, and a second electrode active material layer on a surface of the second electrode current collector; and a separator interposed between the first electrode plate and the second electrode plate. The electrode tab is incorporated into the electrode current collector in an area of either first or second electrode plate where the corresponding electrode active material layer is not coated. The electrode tab is cut widthwise with respect to the electrode current collector from a center area of the electrode current collector and folded, and an insulating tape is adhered to either surface of the electrode tab.
