Abstract
Bipolar electrode is provided with a conductive support/separator perforated on a part which is free from active material with at least one opening which communicates by a gaseous environment in a battery between elements assembled in series. The opening prevents the passage of electrolyte from one conductive support/separator to another, and may include an advantageously hydrophobic material, which also contains an opening therethrough, and is arranged on at least one side of the opening. The bipolar electrodes are particularly applicable to sealed batteries.
