Abstract: A button cell containing electrodes having a polygonal shape, preferably square or hexagonal, in a flat housing is advantageous when compared to such cells having conventional round pressed powder electrodes. The electrodes can be cut from a continuously manufactured rolled strip with a metallic web overlay without appreciable material waste. The webs of the electrodes face outwardly toward the top and bottom of the housing when the electrodes are fitted into the cell. The free space left between the electrode edges and the interior of the cylindrical cell housing is available as electrolyte collecting space and is advantageous for gas take-up.
