摘要： The present invention provides a battery, including a conductive shell and a cover plate assembly, the cover plate assembly and the conductive shell enclose a chamber. The conductive shell or the cover plate assembly are provided with a liquid injection hole communicating with the chamber, a sealing member is disposed on the liquid injection hole to seal the liquid injection hole. A first welding seam and a second welding seam are formed on the sealing member respectively, the first welding seam has a first head end and a first tail end, the second welding seam has a second head end and a second tail end, where the first head end is connected to the second tail end, the second head end is connected to the first tail end, the sealing member is connected to the conductive shell or the cover plate assembly by the first welding seam and the second welding seam. That is, the welding seam for achieving the connection between the sealing member and a conductive top cover is a welding seam of two sections; and by performing welding as sections, there may be an interval of a preset time between the first welding seam and the second welding seam, such that the first welding seam can sufficiently dissipate heat, so as to reduce the heat accumulation of the welding seam, and reduce or avoid the occurrence of the phenomenon of yellowing and bursting points, thereby improving battery yield.
