BUTTON CELL AND ELECTRONIC DEVICE

A button cell and an electronic device relate to the technical field of batteries. The button cell includes a housing (10) and a cover assembly (20); the housing includes a bottom wall (11) and an annular side wall (12); the cover assembly includes a top cover (21) having a through hole at its central area and a conductive member (22) covering the through hole; an outer edge of the top cover (21) is welded with a top of the side wall (12) to form an accommodating chamber (101) for accommodating an electrode assembly (30) and an electrolyte; and the conductive member (22) is disposed on a side of the top cover (21) facing the accommodating chamber (101), and the electronic device body includes the button cell. By disposing the conductive member (22) on the side of the top cover (21) facing the accommodating chamber (101), an extrusion force of the conductive member (22) to the top cover (21) is larger than an adhesive force between a conductive member (22) disposed on a side of a top cover (21) away from the accommodating chamber (101) and the top cover (21) in the prior art, thereby increasing the tolerance of the conductive member (22) to the pressure inside the button cell, reducing the damage caused by the button cell explosion, and improving the safety and stability of the button cell.
