ABSTRACT:
A primary element of the round-cell type is effectively protected from desiccation by a sealing washer made of a flexible foamed plastic (preferably foamed PVC), placed above the depolarization electrode and clamped between the positive cap and the zinc can of the cell. An additional adhesive beading is provided on the carbon rod of the cell to prevent the passage of electrolyte through the central opening in the sealing washer which receives the carbon rod.
