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 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).The invention relates also to a method for producing such a coin cell (200), comprising the step of: stacking together alternatively a positive electrode (203) and a negative electrode (204′, 204, 204″) by placing a separator (202) in-between them to form an assembly of stacked electrodes, packing the assembly of stacked electrodes with said insulating packing tape (205), filling said obtained assembly of stacked electrodes with electrolyte, placing the obtained assembly of stacked electrodes in the cases (201, 208), assembling the cases (201, 208).
