  • Cylindrical battery and manufacturing method thereof
    Patent number: 12183933
    Abstract: A cylindrical battery in which an electrode assembly is housed in a cylindrical can includes a cap assembly covering an upper opening of the cylindrical can; and a gasket disposed in a space between the cylindrical can and the cap assembly. The gasket is disposed on a crimping part formed by processing an end part of the cylindrical can to be bent, and an exposed part of the gasket protruded outside from a space between the cylindrical can and the cap assembly covers a trimming part of the cylindrical can.
    Type: Grant
    Filed: August 19, 2019
    Date of Patent: December 31, 2024
