Embodiment example
[0031] see figure 1 , the present invention provides a technical solution: a new structure of a circular soft-shell battery, including a shell (100) and a top cover (200), and the shell (100) is stamped from a metal material with a thickness of about 30% of the shell material of a traditional cylindrical battery. The sealing part of the mouth is made of a material 3 to 4 times thicker than that of the shell. The sum of the weight of the casing (100) and the metal reinforcing ring (102) is about 50% lighter than that of the same traditional cylindrical battery, so that the strength of the sealing part is stronger.
[0032] In this implementation case, the top cover (200) is stamped and made of a metal material with a thickness about 30% of the shell material of a traditional cylindrical battery, and the sealing part of the mouth is made of a material with a thickness about 3 times that of the shell material. The sum of the weight of the top cover (200) and the metal support ri...
