Estimating the term…
An electrically conductive holder is provided that is suitable for receiving a tablet electrode of a button battery. The holder includes a bottom portion to be fitted coaxially within terminal of a button battery. The holder further includes an upstanding wall portion. The bottom portion is flat and provided with a plurality of apertures through the complete thickness of the bottom portion. At least one group of apertures is distributed at regular angular intervals around the center of the bottom portion, spanning 360°. The strips of solid material of the bottom portion between two adjacent apertures are preferable narrow compared to the dimensions of the adjacent apertures so as to provide a mechanical support for the tablet electrode while also being able to deform under the influence of a volumetric expansion of the electrode.
An electrically conductive holder for holding a tablet-shaped electrode of a button battery pressed into the holder, the holder comprising a bottom portion and a ring-shaped wall portion rising upward from an edge area of the bottom portion, wherein the bottom portion is flat and comprises multiple apertures.
An assembly comprising a holder for holding a tablet-shaped electrode of a button battery pressed into the holder, the holder comprising a bottom portion and a ring-shaped wall portion rising upward from an edge area of the bottom portion, wherein the bottom portion is flat and comprises multiple apertures, and an electrode tablet pressed into the holder.
A button battery comprising a holder for holding a tablet-shaped electrode of a button battery pressed into the holder, the holder comprising a bottom portion and a ring-shaped wall portion rising upward from an edge area of the bottom portion, wherein the bottom portion is flat and comprises multiple apertures, the holder comprising a tablet-shaped cathode pressed into the holder, the battery comprising a can, a lid, a separator sheet and an anode, and wherein the holder is placed with its bottom portion in physical contact with the bottom of the can, while the separator sheet and the anode are placed on top of the cathode.
