摘要： The present invention relates to multilayer packaging structure (10) for a thin film battery (5) wherein a metal layer (14) is sandwiched between a first layer (11) and a second layer (12). A first opening (21) is arranged in the first layer (11) such that a first portion (24) of the metal layer (14) associated with the first opening (21) is exposed and is configured to be able to be in electrical contact with a current collector of the thin film battery (5). A second opening (22) is arranged in the second layer (12) such that a second portion (25) of the metal layer (14) associated with the second opening (22) is exposed and is configured to be able to be electrically connected to an external circuitry. The invention further relates to a method (30) for manufacturing of the multilayer packaging structure (10).

摘要： 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).

摘要： According to the method of the invention, a current collector (5a, 5b) for a thin battery is produced by a printing or spray deposition technique on a substrate (1) formed of a battery packaging material. The layer obtained by printing or spray deposition comprises particles of an electrically conductive material. The printing or spraying step is followed by curing using a light source, to thereby obtain the current collector. The printed or sprayed layer is produced having the required form of the current collector, so that no stamping or other forming operations are required. Current collectors according to the invention have comparable or improved mechanical and electrical properties to the traditional foil or mesh-based current collectors.
