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).
