Abstract
The present invention discloses a rechargeable button cell, which includes an anode shell, a cathode shell and a coiled electric core. The anode shell and the cathode shell define a receiving cavity in which the coiled electric core is located. A channel that extends in an axial direction of the rechargeable button cell is provided in the middle of the coiled electric core. An electrically conductive bar that extends on the cathode shell is located in the channel. An anode tab and a cathode tab of the coiled electric core are provided on the same side, which facilitates monitoring the conditions of the two tabs at the same time during the production and preventing the tabs from being damaged, thereby achieving good weldability and improving the assembling efficiency.
