Description

Es ist bekannt, Elektroden für elektrische Sammler mit alkalischen Elektrolyten dadurch herzustellen, daß die wirksame Masse, z. B. Nickeloxydulhydrat oder Kobaltoxydulhydrat S oder andere schlecht leitende Sauerstoffverbindungen, ohne Zusatz eines inaktiven Leitmittels in Metalltuch oder Metallgaze von äußerster Feinheit der Maschen verrieben und das gepastete Metalltuch in geeignete FormenIt is known to make electrodes for electrical collectors with alkaline electrolytes produce that the effective mass, e.g. B. nickel oxide hydrate or cobalt oxide hydrate S or other poorly conductive oxygen compounds, without the addition of an inactive conductive agent rubbed in metal cloth or metal gauze of extremely fine mesh and the pasted metal cloth into suitable shapes

ίο zusammengelegt wird. Die Formen werden dabei durch Herumwickeln des gepasteten; Metalltuches um einen Ableitungskörper, durch Aufeinanderlegen in Lagen und darauffolgendes Pressen geformt oder durch Falzen oder Wellen und darauffolgendes Pressen gebildet. Auch ist es bekannt, das Metall-! tuch durch auf mechanischem oder chemischem Wege gerauhtes un,d gelochtes Metallblech zu ersetzen.ίο is merged. The shapes are made by wrapping the pasted; Metal cloth around a discharge body, by laying one on top of the other in layers and then following Pressing shaped or formed by folding or corrugating and then pressing. Also it is known the metal! Cloth through mechanically or chemically roughened and perforated sheet metal to replace.

ao Gegenstand der Erfindung ist nun eine Verbesserung dieser bekannten Verfahren, darin bestehend, daß die durch Zusammenlegen der gepasteten Metallflächen, gebildeten Formkörper einem Preßdruck parallel zur Richtung der metallischen Zwischenschichten unterworfen werden. Dies geschieht zweckmäßig in der Weise, daß die gepasteten Metallflächen in Streifenform um einen hohlen Kern ganz oder annähernd gleicher Breite herumgelegt und die so gebildeten. Scheiben senkrecht zu ihrer Ebene in Formen zusammengedrückt werden. Dadurch wird nicht) nur ein sehr inniger Zusammenhalt des Elektrodenmaterials und eine gedrungene Form der Elektroden selbst, sondern auch der Vorteil erzielt, daß diejenigen Flächen der Elektroden, welche die größte Ausdehnung besitzen und nach Einbau in den Sammler einander benachbart sind, während der Benutzung desselben nicht mehr der Gefahr unterworfen sind, daß sie sich infolge der chemischen Vorgänge während des Ladeng und Entladens ausdehnen oder ausbeulen und so einen Kurzschluß hervorrufen.The invention also relates to an improvement this known method, consisting in that the molded body formed by joining the pasted metal surfaces subjected to a pressing pressure parallel to the direction of the metallic intermediate layers will. This is expediently done in such a way that the pasted metal surfaces wrapped around a hollow core in the form of strips, wholly or approximately the same width and those so educated. Slices compressed into shapes perpendicular to their plane will. This not only results in a very intimate cohesion of the electrode material and a compact shape of the electrodes themselves, but also the advantage that those areas of the electrodes which have the greatest expansion and are adjacent to one another after being installed in the collector, during use the same are no longer subject to the risk that they are due to the chemical processes during the Ladeng and discharge, expand or bulge, causing a short circuit.

Die Zeichnung veranschaulicht schematisch das neue Verfahren, wobei die Elektroden in ungefähr natürlicher Größe dargestellt sind.The drawing illustrates schematically the new process, with the electrodes are shown in approximately natural size.

Gepastetes Metalltuch oder "mechanisch oder chemisch gerauhtes und durchlochtes Metallblech wird in Streifen, von beispielsweise 8 mm Breite auf einen hohlen Kern 1, (Abb. ι und 2), zweckmäßig in Spiralen 2, aufgewickelt, bis eine Scheibe von z. B. 5 cm Durchmesser (Abb. 1) entsteht. Diese Scheibe wird nun einem Preßdruck senkrecht zur Fläche der Scheibe unterworfen. Dies geschieht vorteilhaft in einer Form (Abb. 2), Pasted metal cloth or "mechanically or chemically roughened and perforated metal sheet is wound up in strips, for example 8 mm wide, on a hollow core 1 (Fig. 1 and 2), expediently in spirals 2, until a disk of, for example, 5 cm in diameter (Fig. 1). This disc is now subjected to a pressure perpendicular to the surface of the disc. This is advantageously done in a form (Fig. 2),

die aus einem mit mittlerem Dom 3 versehenes· Bödfenteil 4" und einer beweglichen Preßplatte 5 besteht. Der hohle Kern 1 ist zweckmäßig an seinen Kanten etwas umgebördelt. Der Preßdruck wird nun so stark gemacht, daß sich die Scheibe auf beispielsweise 4 mm zusammendrückt. Nach Herausnahme aus der Form hat die Scheibe in. Draufsicht also etwa die Gestalt der Abb. 3.which consists of a central dome 3 Base part 4 "and a movable one Press plate 5 consists. The hollow core 1 is appropriately beaded somewhat at its edges. The pressure is now made so strong that the disc on, for example 4 mm compressed. After removal from the mold, the disc has in. Top view thus roughly the shape of Fig. 3.

Der hohle Kern 1 ist dann noch schärfer an seinen Rändern umgebördelt. Eine ähnliche Form besitzen aber auch die metallischen Zwischenschichten der Wickellagen 2. Die Folge ist also, daß an den größten Flächen der Scheiben Metallumbördeiungen entstanden sind, die während der späteren Benutzung der Scheiben als Elektroden eine Ausdehnung des aktiven Materiales senkrecht zu den Scheibenflächen ver-The hollow core 1 is then even sharper beaded at its edges. However, the metallic ones also have a similar shape Intermediate layers of the winding layers 2. The result is that metal flanges on the largest surfaces of the disks which caused an expansion of the active material during the later use of the panes as electrodes perpendicular to the disc surfaces

ao hindern. Die Scheiben werden sich vielmehr nur in radialer Richtung ausdehnen.ao prevent. Rather, the disks will only expand in the radial direction.

Der hohle Kern 1 wird aus einem geeigneten Metall, z. B. Nickel, hergestellt. Ehe die Scheibe dem Druck ausgesetzt wird, istThe hollow core 1 is made of a suitable one Metal, e.g. B. nickel, made. Before the disc is subjected to pressure, is

as es vorteilhaft, sie in einem passenden Ofen zu trocknen. Die Struktur der Scheibe nach der Pressung ist sehr homogen, aber doch' noch so durchlässig, daß der Elektrolyt gut diffundieren kann.As it is advantageous to put them in a suitable oven to dry. The structure of the disc after pressing is very homogeneous, but still ' still so permeable that the electrolyte can easily diffuse.

Die so gewonnenen Elektroden werden dann nach Art der Abb. 4 zusammengebaut, indem sie auf einen isolierenden Stab 6 unter Zwischenschaltung von Isolierstücken 7 derart aufgereiht werden, daß positive mit negativen Elektroden abwechseln. Die ganze Gruppe kann dann in einen Stahlzylindeu eingebaut werden, der an beiden Seiten durch eingeschweißte Stahlscheiben mit passenden Öffnungen für die positiven und negativen Ableitungen, zweckmäßig jeweils an den entgegengesetzten Enden der Zylinder, versehen ist.The electrodes obtained in this way are then assembled as shown in Fig. 4, by placing them on an insulating rod 6 with the interposition of insulating pieces 7 in this way be lined up that alternate positive with negative electrodes. The whole group can then be put into a steel cylinder can be installed, on both sides by welded steel disks with matching Openings for the positive and negative leads, expediently on the opposite sides Ends of the cylinder.

Selbstverständlich brauchten die Scheiben nicht rund zu sein, sondern könnten jede be-Of course, the panes did not need to be round, but could be any

Audi brauchten die einzelnen Schichten nicht durch Wickeln hergestellt zu werden. Ein Falzen oder sonstiges Zusammenlegen würde zu dem gleichen Ziele führen.have lovable form. For this purpose, there is only one other shape of the hollow core 1 and one other shape of the forms 4 necessary. Audi didn't need the individual shifts Winding to be made. Folding or other folding would result in that lead to the same goals.
