摘要： The present application provides a battery cell, including a cover plate, a housing, and a gas-permeable film. The housing has an opening, and the cover plate covers the opening of the housing. The cover plate and/or housing have/has at least one through hole, and the inside and the outside of the battery cell are in communication with each other via the through hole; and the gas-permeable film is connected to the inside of the cover plate and/or housing and covers the at least one through hole. According to the battery cell of the present application, gas inside a battery can be discharged to prevent the gas from accumulating inside the housing, thereby improving performance of an electrode assembly, prolonging service life of a secondary battery, and ensuring safety performance of the battery cell.

摘要： 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.
