Patentansprüche:Patent claims: 1. Verfahren zur Herstellung bipolarer Elektroden für Nickel-Cadmium-Batterien, die aus einer metallisch leitfähigen, ionenundurchlässigen Trägerunterlage mit beidseitig aufgesinterten Metallgerüsten zur Aufnahme der aktiven Massen bestehen, dadurch gekennzeichnet, daß mit Hilfe der ionenundurchlässigen beidseitig besinterten Elektrode (2) ein Elektrolysebehälter (1) in zwei Räume unterteilt wird, aus denen gleichzeitig die aktiven Massen entgegengesetzter Polarität in die beidsejtigen Sintergerüste elektrolytisch in einem Arbeitsgang eingelagert werden.1. Process for the production of bipolar electrodes for nickel-cadmium batteries, which are made from a metallically conductive, ion-impermeable support base with sintered on both sides There are metal frameworks for receiving the active masses, characterized in that an electrolysis tank with the aid of the ion-impermeable electrode (2), which is sintered on both sides (1) is divided into two spaces, from which at the same time the active masses of opposite one another Polarity can be stored electrolytically in the two-sided sintered frameworks in one operation. 2. Verfahren nach Anspruch 1, gekennzeichnet durch seine Anwendung auf Sinterelektroden, deren Porenvolumen auf einer Seite größer ist als auf der Gegenseite.2. The method according to claim 1, characterized by its application to sintered electrodes, whose pore volume is larger on one side than on the opposite side.
