BUTTON CELL AND ELECTRONIC DEVICE

The present disclosure provides a button cell and an electronic device. The button cell includes a case, a cell, a conductive member arranged on the case and connected to the case in an insulated manner, and a liquid injection port for injecting an electrolyte solution into an accommodating cavity. A cell is placed in an accommodating cavity of a bottom shell. A first tab is welded to an inner bottom wall of the bottom shell, and then the top cover having the conductive member is connected to the bottom shell in a sealed manner, with a second tab on the cell being electrically connected to the conductive member. Finally, an electrolyte solution is injected into the accommodating cavity. After the electrolyte solution is injected, a sealing member covers the liquid injection port, and the sealing member is connected to the liquid injection port in a sealed manner.
