Abstract: The invention relates to a coin cell (200) comprising two cases (201, 208) designed to form a housing, an assembly of stacked electrodes placed inside the housing and comprising at least one positive electrode (203), at least one negative electrode (204, 204?, 204?), and at least one separator (202) placed in-between them. It further comprises a insulating packing tape (205) comprising an insulator basis (205a) and at least one packing flap (205b) integral with the insulator basis (205a), said insulating packing tape (205) being placed in such a way that the insulator basis (205a) is between the assembly of stacked electrodes and one of the cases (208) to avoid electrical contact between the assembly of stacked electrodes and said case (208) and the packing flap (205b) holds the assembly of stacked electrodes to form an electrode pack (209).

Abstract: Multiple blister pack (1) for button batteries comprising a blister foil (10) designed to provide individual storage cups (12) of center (C) and diameter (D) for receiving a button battery, and individual closure regions (13) for each said individual storage cup (12). Each closure region (13) receives a closure element (4), and the individual storage cups (12) are arranged on the blister foil (10) according to a matrix pattern with at least two columns. Each closure region (13) surrounding each individual storage cup (12) are mutually separated by column and row tearing lines (2,2?). The closure element (4) and/or the closure region (13) is provided with tracking information concerning the battery stored in said individual storage cup (12) and the centers (C) of the individual storage cups (12) are spaced apart of a distance equal to twice the diameter (2*D) of the individual storage cup (12) from each other along each column of said matrix, within a tolerance of 1 millimeter.

Abstract: The present invention relates to a galvanic element, in particular an element of the button cell type, which has a long service life even when there are high mechanical or thermal loads. The element has a cathode, an anode, an electrolyte, a separator arranged between the anode and cathode, and a housing, which comprises a housing cup, a housing cover and a sealing element, the sealing element insulating the housing cup against the housing cover. According to the invention, the sealing element is rigidly connected to the separator.

Abstract: Blister pack 1 for button battery comprising a blister foil 10 designed to provide at least an individual cup 12 for receiving a button battery, and an individual closure region 13 for each said individual cup 12. The closure region 13 receives a closure element 4 which is removably secured to the closure region 13.

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.
