Zusammenfassung:PCT No. PCT/EP97/02061 Sec. 371 Date Sep. 23, 1998 Sec. 102(e) Date Sep. 23, 1998 PCT Filed Apr. 23, 1997 PCT Pub. No. WO98/33223 PCT Pub. Date Jul. 30, 1998A bipolar electrode for alkaline batteries, including a conductive screen, a tridimensional collector provided with asperities which is plated on each side of the conductive screen, active material filling the collectors in order to constitute positive and negative electrodes, respectively, wherein at least one of each side of the conductive screen is grooved and the tridimensional collector is affixed to the conductive screen by means of a non-conductive adhesive, stable in the presence of a highly alkaline electrolyte, in direct contact with the external sides of the conductive screen by means of the asperities of the tridimensional collector.
