HIGH PERFORMANCE BATTERY AND CURRENT COLLECTOR THEREFOR

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 positive 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 plate. 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 from the adjacent unexposed bottom edge of the other (i.e., the non attached) electrode plate. The current collector includes a terminal mounting portion and a radially extending collecting web. The collecting web of the current collector includes a perimeter, at least one open ended perimeter aperture located at the perimeter and extending radially inwardly therefrom, and at least one closed end internal aperture positioned between the terminal portion and the perimeter. Also, the current collector may have recessed areas surrounding the apertures to facilitate joining of the current collector and the electrode plate. Se describe un ensamble de devanado para una bateria que incluye una placa de electrodo positivo, una placa de electrodo negativo, una lamina separadora, y un colector de corriente; Las placas positivo y negativa y la lamina separador estan devanadas en una relacion traslapante, de manera que la lamina separadora esta colocada entre las placas positiva y negativa, un borde superior expuesto de la placa de electrodo positivo esta separado longitudinalmente desde un borde superior no expuesto adyacente, y un borde inferior expuesto de la placa de electrodo negativo esta longitudinalmente separado de un borde inferior no expuesto de la placa de electrodo positivo; el colector de corriente esta conectado a uno de los bordes expuestos de una de las placas de electrodo positivo y negativo, y, por consiguiente, esta separado del borde inferior no expuesto adyacente de la otra placa de electrodo (es decir, la que no esta unida); el colector de comente 40A incluye una porcion de montaje de terminal (44) y una banda de recoleccion (43) radialmente extendida; la banda de recoleccion del colector de corriente in
