Abstract
A battery cell, a manufacturing method, a manufacturing system, a battery and an electrical device are provided. In some embodiments, the battery cell of includes an electrode component; a casing for accommodating the electrode component and having an opening; an end cap for sealing the opening of the casing; a current collector member for electrically connecting the electrode component and the end cap, the current collector member including a base portion and an elastic portion connected to the base portion. The elastic portion abuts against the electrode component, so the elastic portion is not required to be welded to the electrode component, thus reducing metal particles to lower the risk of short circuit. The elastic portion is able to deform when squeezed by the electrode component and release the pressure therebetween by deformation, reducing the risk of crushing the electrode component due to excessive pressure.
