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.

Button-type battery

Disclosed are a battery apparatus and an electronic device. The battery apparatus includes: a first shell including a first tubular side wall and a top cap; and a second shell including a second tubular side wall and a bottom cap, wherein a recessed structure is formed in at least part of a connection region between the second tubular side wall and the bottom cap; the first tubular side wall sleeves the second tubular side wall; an insulation sealing piece is arranged between the first tubular side wall and the second tubular side wall; a portion of the first tubular side wall close to its open end is bent towards the recessed structure along part of a circumference of the open end to form a partial crimped edge; and the partial crimped edge is clamped to the recessed structure.
