 faden gesichert wird. Es kann auch die fertige Elektrode mit Baumwolle direkt   umspannen   werden, alsdann ist die Elektrode fertig zum Gebrauch. Durch die äusserst feine Verteilung der schlecht leitenden aktiven Masse in den feinen Maschen des Metalltuches wird der Zusatz des inaktiven   Leitmittels   überflüssig.

   Die Punktion des inaktiven   Leitmittels     übernimmt   das Metalltuch, welches gleichzeitig als äusserst leichter, vorzüglich leitender Träger von   grosser   Oberfläche dient, welcher durch das Aufrollen äusserst geringe räumliche   Abmessunsn aufweist.   Durch das feste Aufrollen des Metalltuches zu einem Stab erhält die aktive Paste sicheren festen Kontakt in und mit dem Metalltuch, während gleichzeitig die übereinander gelagerten Metalltuchschichten ein Ausschwemmen der Masse unmöglich machen, trotz genügender Diffusionsmöglichkeit des Elektrolyten. Durch das Umwickeln und Sichern mit indifferentem nichtleitenden Stoff wird das Ausschwemmen der Masse aus den feinen Poren der äussersten Lage verhindert.

   Eine derartig hergestellte Elektrode ist durch etwa auftretende Gasspannungen und   Volumenänderungen   der aktiven Materialien während der Ladung und Entladung   unbeeinflussbar,   vielmehr bleibt der Kontakt stets vollkommen erhalten. Gegen   Erschütterungen   und mechanische äussere Einflüsse ist die beanspruchte Elektrode äusserst widerstandsfähig. Eine Anzahl der vorbeschriebenen walzenförmigen Elektroden wird in einen Träger aus geeignetem Material, zweckmässig Nickel, eingesetzt, und zwar ohne Abstand oder mit geringem Abstand voneinander.

   Das Befestigen dieser Elektrodenwalzen in dem Rahmen erfolgt so, dass der in der Mitte jeder Elektrodenwalze auf beiden Enden herausragende Ableitungsdraht (Fig. 3) durch mechanische Verbindung (Nieten) oder Verschweissen mit dem Rahmen innig verbunden wird (Fig.   4).   



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Elektroden für elektrische Sammler mit alkalischem Elektrolyten, dadurch gekennzeichnet, dass die wirksame Masse, z. B.   Nickeloxydulhydrat   oder Kobaltoxydulhydrat oder andere   achlechtleitende   Metall-Sauerstoffverbindungen ohne Zusatz eines inaktiven   Leitmitteln   in Metalltuch oder Metallgaze von äusserster Feinheit der Maschen verrieben und das pastierte Metalltuch in geeignete Form zusammengelegt wird.

 thread is secured. The finished electrode can also be directly covered with cotton, then the electrode is ready for use. Due to the extremely fine distribution of the poorly conductive active material in the fine mesh of the metal cloth, the addition of the inactive conductive agent is superfluous.

   The puncture of the inactive conductive agent is performed by the metal cloth, which at the same time serves as an extremely light, excellently conductive carrier with a large surface, which has extremely small spatial dimensions due to the rolling up. By firmly rolling up the metal cloth to form a rod, the active paste has secure, firm contact in and with the metal cloth, while at the same time the layers of metal cloth superimposed on one another make it impossible for the mass to be washed out, despite sufficient diffusion possibilities for the electrolyte. By wrapping and securing with indifferent, non-conductive material, the mass is prevented from being washed out of the fine pores of the outermost layer.

   An electrode produced in this way cannot be influenced by any gas tensions and volume changes in the active materials during charging and discharging; rather, the contact is always completely maintained. The stressed electrode is extremely resistant to vibrations and external mechanical influences. A number of the above-described roller-shaped electrodes are inserted into a carrier made of a suitable material, suitably nickel, with no spacing or a small spacing from one another.

   These electrode rollers are fastened in the frame in such a way that the drain wire protruding at both ends in the middle of each electrode roller (Fig. 3) is intimately connected to the frame by mechanical connection (riveting) or welding (Fig. 4).



   PATENT CLAIMS:
1. A method for the production of electrodes for electrical collectors with alkaline electrolytes, characterized in that the effective mass, for. B. nickel oxide hydrate or cobalt oxide hydrate or other poorly conductive metal-oxygen compounds without the addition of an inactive conductive agent in metal cloth or metal gauze of extremely fine meshes and the pasted metal cloth is put together in a suitable form.
