Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a stainless steel shell shearing type scoring structure device and a battery. Background Art

[0002] Nowadays, new energy is widely used, and the demand for stainless steel shells, as one of the most important structural parts in batteries, has increased dramatically. In the traditional stainless steel shell-explosion-proof sheet scoring structure, the stainless steel shell is a V-shaped scoring structure (the structure is as shown in the attached manual). Figure 3 and 4 As shown in the figure, the product stability of this structure is poor, it is easy to deform, and the battery will leak after assembly. These undesirable conditions make it difficult to guarantee the quality of stainless steel shell products and battery assembly products. In addition, this production model has high costs, low pass rates, high investment and low returns, which makes it difficult for the company to bear. Utility Model Content
