Abstract: A button battery (1?,1?) that includes a sealing assembly, having one of the terminals (9) of the battery, an electrically insulating portion (17) and a circumferential wall portion (15). The insulating portion (17) forms a hermetic bond with the terminal (9) and with the wall portion (15). The sealing assembly is receptacle-shaped and one or more components of the battery such as the anode (8), the separator sheet (7) and the cathode (3) may be inserted in the receptacle shape prior to assembling the battery. The wall portion (15) forms a part of the second terminal and is attached to the remainder of the second terminal by a circumferential weld seam (16). The battery may be produced by inserting one or more components of the battery into the sealing assembly and attaching the wall portion (15) of the sealing assembly to the remainder (2,2?) of the second terminal.

Abstract: The smart battery (1) includes an electronic module provided with an electronic circuit (8) for controlling the supply voltage, which is disposed in a case having a cover (2) as the external negative terminal, fixed to a cup (3), as the external positive terminal. A first chemical substance (4) as the anode and a second chemical substance (5) as the cathode, are inside the case. The electronic module includes a printed circuit board (7) having a first face with conductive paths, connected to the electronic circuit, and a second insulating face fixed to the second chemical substance. The electronic circuit is connected at output to a first connection pad connected to the cup. The electronic circuit is connected to the chemical substances by a second connection pad on a first tab (7?) and by a third connection pad on a second tab (7?) folded at 180° on the second face of the printed circuit board.
