Example Embodiment
[0050] Embodiment 1. A battery, combined figure 2 , image 3 As shown, it includes a battery container 1, an electrode assembly contained in the battery container 1, a cover plate assembly for sealing the battery container 1, wherein the cover plate assembly includes an assembly seat 17, a cover plate 15, an insulating member 11, and an explosion-proof film 8 and pull plate 5. The assembling base 17 is an assembling plate welded on the re-battery container 1. The assembling plate has a cover plate hole 19, and a cylinder body 25 extending upward is formed around the cover plate hole 19, and a vertical connection is formed in the cylinder body 25. Cavity 28. There is an annular table surface 18 around the cover plate hole 19 in the cylinder body. The upper part of the cylinder body 25 is bent inwardly (the bent portion 16) to form an annular sealing groove 29 on the inner wall of the cavity 28 of the assembly seat 17. The cover plate 15 serving as the electrode for drawing current ...
