Abstract

Se describen un método de enrollado, una máquina enrolladora, un conjunto de electrodo y una celda de batería. El método de enrollado comprende: sujetar los cabezales de una 5 placa de ánodo, de una placa de cátodo y de un separador entre una primera media aguja de enrollado y una segunda media aguja de enrollado de un conjunto de aguja de enrollado en un puesto de enrollado; y girar el conjunto de aguja de enrollado en el puesto de enrollado para enrollar la placa de ánodo, la placa de cátodo y el separador para formar un conjunto de electrodo. Al adoptar la solución, se puede resolver el problema de que, en algunos casos, cuando se enrollan una placa de cátodo, una placa de ánodo y un separador, los cabezales de la placa de cátodo y de la placa de ánodo son propensos a doblarse.
