The bipolar electrode comprises a conductive partition (5) pierced, on a part (8) free of active materials, of at least one orifice (9) allowing the elements assembled in series to be put into communication by the gaseous environment. The orifice (9) does not allow the possible passage of the electrolyte from one element to the other, thanks to an additional thickness of advantageously hydrophobic material, itself pierced, disposed on each side around the orifice (9 ).n n n Application to sealed storage batteries. |
