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.
