Abstract: In a battery having a wound electrode element which is made contact with by means of a pin, a contact connection is fitted on the outer face and is electrically connected to the pin which is arranged in the housing. The connection between the pin and the contact connection can also be tightened mechanically. In consequence, the pin can be used at the same time as the holding element for the wound electrode, which leads to space being saved within the battery housing. Furthermore, the connection which can be tightened mechanically can be produced very easily, is robust and is scarcely susceptible to corrosion. It also allows a seal, which is impermeable to gases, for the battery interior. The battery is particularly suitable for mobile small and miniature appliances which draw a high current, so that their battery must be replaced frequently.

Abstract: In a battery having a wound electrode element (28) which is made contact with by means of a pin (25), a contact connection (23a) is fitted on the outer face and is electrically connected to the pin (25) which is arranged in the housing (24). The connection (21, 25) between the pin (25) and the contact connection (23a) can also be tightened mechanically. In consequence, the pin (25) can be used at the same time as the holding element for the wound electrode (28), which leads to space being saved within the battery housing (24). Furthermore, the connection (21, 25) which can be tightened mechanically can be produced very easily, is robust and is scarcely susceptible to corrosion. It also allows a seal, which is impermeable to gases, for the battery interior. The battery is particularly suitable for mobile small and miniature appliances which draw a high current, so that their battery must be replaced frequently.

Abstract: Blister pack for button batteries (5) having a substrate card (1) of cardboard, on which a two-dimensionally stabilizing main panel (2) and an edge-oriented battery receiving area (4) are bounded by a straight line of weakness (3). On the receiving area (4) there are separating cuts (6) along the line of weakness (3) at right angles from the latter to the substrate card edge, as a result of which individual compartments (7) are formed, which are made pivotal independently of one another about the line of weakness (3).
