Abstract
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.
