The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: A battery sealing structure and a battery. The battery sealing structure comprises: a battery cell cover plate or a casing, provided with a liquid injection hole running through a main body thereof; and a sealing member, welded and connected to the liquid injection hole, so that a welding portion is formed between at least a portion of the circumferential side wall of the sealing member and at least a portion of the hole wall of the liquid injection hole, wherein the welding portion has a penetration depth L1=500-1000 µm and a weld width L2=500 µm. The battery sealing structure ensures a reliable connection between the sealing member and the liquid injection hole by defining the sizes of the penetration depth L1 and the weld width L2 of the welding portion, thereby effectively preventing electrolyte leakage, meeting sealing requirements of battery electrolytes, improving the yield of batteries and prolonging the service life of the batteries, and ensuring usage safety of the batteries.
