Abstract

Batería que comprende: un cátodo que tiene una capa de recubrimiento de material activo de cátodo prevista sobre al menos una superficie de un colector de cátodo; y un ánodo que tiene una capa de recubrimiento de material activo de ánodo prevista sobre al menos una superficie de un colector de ánodo, enrollándose el cátodo y ánodo para estar enfrentados entre sí con un separador interpuesto entre los mismos, en la que la capa de recubrimiento de material activo de cátodo aplicada a la al menos una superficie del colector de cátodo se desvía longitudinalmente de una capa de recubrimiento de material activo de cátodo aplicada a la otra superficie del colector de cátodo de tal manera que las partes de comienzo y finalización de aplicación de ambas capas de recubrimiento de material activo de cátodo no concuerdan entre sí, y sólo al menos una de una parte de comienzo de enrollado y una parte de finalización de enrollado del cátodo está dotada de una parte no recubierta de cátodo para la instalación de un cable de cátodo, y en la que se une una cinta aislante al límite de la capa de recubrimiento de material activo de cátodo en una posición en la que la capa de recubrimiento de material activo de ánodo está enfrentada a una parte sin recubrimiento del cátodo que no contiene la capa de recubrimiento de material activo de cátodo, en la que el cable de cátodo y el cable de ánodo de la batería están dispuestos en sentidos opuestos, en la que el cable de cátodo y el cable de ánodo están dispuestos en la parte de comienzo y la parte de finalización de enrollado, respectivamente, o el cable de cátodo y el cable de ánodo están dispuestos en la parte de finalización de enrollado y la parte de comienzo de enrollado, respectivamente, y en la que al menos un lado del cátodo no está dotado de la parte no recubierta de cátodo.
