Technical field

[0002] The invention relates to the technical field of batteries, in particular to the technical field of square steel shell batteries and modules assembled into battery systems.

[0003]

Background technique

[0004] With the development of green and environmentally friendly new energy businesses, square steel shell batteries with strong alkaline aqueous solutions with various structural designs have appeared. The characteristics are summarized as follows: 1. The design structure of single or module batteries has a top current collector (Hunan Shenzhou, Fujian Weidong, Sichuan Wankaifeng, Shandong Guoli, Anhui Guoxuan, etc.) 2. In order to increase the strength of the battery case or battery cover, the ability to resist deformation and twisting, it is usually realized by increasing the thickness of the material, punching the concave-convex structure, and through the bundled design of the module; 3. For the internal pressure of the battery The way ...
