ABSTRACT:
The present invention provides an electrochemical cell having a liquid electrolyte and spiral-wound electrodes provided with an axial chimney for electrolyte filling purposes and placed inside a cylindrical or prismatic enclosure so as to leave a duct between the outside periphery of the spiral-wound electrodes and the inside wall of said enclosure in order to exhaust air displaced by the electrolyte, the cell including a washer disposed between said enclosure and the spiral-wound electrodes at the end of said chimney that is furthest from the electrolyte inlet, said washer being provided with at least one opening putting said chimney into communication with said duct.
