Abstract
A button-type battery of the present disclosure is provided with a package assembly and a rolled cell. In an actual application process, both a battery cup and a battery cover have a protective function, while a sealing plastic ring has a waterproof function. In addition, when an electrode tab needs welding, position of the electrode tab is determined, and the battery cup and/or the battery cover are subjected to resistance welding. Accordingly, a center welding layer is formed by resistance welding on a contact portion at a central position where the electrode tab of the rolled cell contacts the battery cup and/or the battery cover, and an edge welding layer is formed by resistance welding on a contact portion at an edge position where the electrode tab of the rolled cell contacts the battery cup and/or the battery cover.
