Zusammenfassung:A winding assembly for a battery includes a positive electrode plate, a negative electrode plate, a separator sheet, and a current collector. The positive and negative plates and the separator sheet are wound in overlying relationship such that the separator sheet is positioned between the positiv e and negative plates, an exposed top edge of the positive electrode plate is spaced longitudinally from an adjacent unexposed top edge of the negative plate, and an exposed bottom edge of the negative electrode plate is spaced longitudinally from an unexposed bottom edge of said positive electrode plat e. The current collector is connected to one of the exposed edges of one of the positive and negative electrode plates, and, accordingly, is spaced apart fr om the adjacent unexposed bottom edge of the other (i.e., the non-attached) electrode plate. The current collector (40A) includes a terminal mounting portion (44) and a radially extending collecting web (43). The collecting we b of the current collector includes a perimeter, at least one open-ended perimeter aperture (52) located at the perimeter and extending radially inwardly therefrom, and at least one closed-end internal aperture (54) positioned between the terminal portion and the perimeter. Also, the current collector may have recessed areassurrounding the apertures to facilitate joining of the current collector and the electrode plate.
