Abstract

La capacidad de una pila electroquímica de alta capacidad puede ser incrementada a través de la seleccion de sus componentes a fin de lograr ciertasrelaciones volumétricas dentro de la misma. Estas relaciones volumétricas específicas que conducen almejoramiento de la capacidad comprenden la relacion delvolumen interno de la pila al volumen externo, la relacion del volumen del cierre al volumen externo, la relacion del volumen del cierre al volumen interno dela pila, la relacion del volumen de obturacion al volumen interno de la pila y la relacion del volumen de obturacion al volumen interno de la pila y larelacion del volumen de obturacion al volumen externo. Un método de fabricacion de una pila electroquimica que comprende: el montaje deuna carcasa y uncierre, la carcasa posee cierto diámetro interno, un extremo cerrado que posee una superficie terminal cerrada interna, y un extremo abierto, en tanto elcierre de la pila comprende una junta aislante que posee cierto volumen y una caperuza terminal, conformando la junta y la caperuza conjuntamente el cierre dela pila, en tanto la carcasa y el cierre de la pila se encuentran unidos en el extremo abierto de la carcasa estando la junta aislante ubicada entre lacarcasa y la caperuzaterminal para configurar la pila, en tanto el cierre presenta una superficie interna y cierto volumen, mientras que la pila posee unvolumen interno definido por la superficie interna del cierre, la superficie terminal cerrada interna, y el diámetro interno, y un diámetro externo y unaaltura externa dentro de un límite de tamano que posee cierto volumen externo, donde la relacion del volumen interno al volumen de la pila es superior aaproximadamente 0,83; volumen de obturacion al volumen internode la pila es inferior a aproximadamente 0,02; la relacion del volumen de obturacion alvolumen externo es inferior a 0,02; la relacion del volumen del cierre al volumen interno de la pila es inferior a aproximadamente 0,06; y la relacion delvolumendel cierre al volumen externo es inferior a aproximadamente 0,05. Una pila electroquímica obtenida mediante el método descripto que comprende: una
