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: A multilayer (200) for a lithium-ion battery having a structure including at least a polyolefin based substrate layer (204) forming the inner layer of the multilayer separator (200); a resin layer (203) stacked on both surface of the polyolefin substrate layer (204), the resin layer (203) being formed from a polyolefin; a cellulose fibers based outer layer (202) stacked on the surface of each resin layer (203).

Abstract: 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).
