Description

Verfahren zur Herstellung gepreßter Depolarisationsmasseplatten für galvanische Elernente Es ist bekannt, plattenförmige Elektroden für galvanische Elemente aus einer Graphitschicht und einer Depolarisationsmasseschicht zu einem einheitlichen Gebilde zusammenzupressen. Beim Zusammensetzen solcher Platten zu Batterien war es erforderlich, zur Schaffung des Elektrolytraumes .einen besonderen, vorher hergestellten Isolierrahmen zu verwenden.Process for the production of pressed depolarization mass plates for galvanic elements It is known, plate-shaped electrodes for galvanic Elements from a graphite layer and a depolarization mass layer to one to compress a uniform structure. When assembling such panels too Batteries it was necessary to create the electrolyte space. to use previously manufactured insulating frames.

Die Benutzung eines solchen fertigen Rahmens behindert sehr stark eine rationelle Reihenfabrikation.The use of such a ready-made frame is very hindering a rational serial production.

Gemäß der Erfindung wird di=eser" Mangel dadurch behoben, daß der -Isolierrahmen bzw. die Begrenzungswände des Elektrolytraumes in einem Arbeitsgange bei der Pressung des Depolarisators und der positiven Schicht hergestellt wird. Hierdurch entfällt nicht nur das Einlegen Beines. besonderen Isolierrahmens, sondern es wird auch eine sehr feste und dauerhafte Verbindung der Masseplatte mit den Elektrolytraumwänden herge stellt, so daß das ganze Gebilde eine hohe Stabilität erhält.According to the invention, this "deficiency is eliminated in that the -Isolierrahmen or the boundary walls of the electrolyte space in one operation is produced during the pressing of the depolarizer and the positive layer. This not only eliminates the need to insert a leg. special insulating frame, rather there will also be a very firm and permanent connection between the ground plane and the electrolyte compartment walls Herge provides, so that the whole structure is given a high level of stability.

Es ist bekannt, in gepreßten Kohleplatten für galvanische Elemente einen Hohlraum zur Aufnahme des Elektrolyten vorzusehen und einen besonderen Isolierrahmen ,auf die vorstehenden Kanten dieses so geschaffenen Raumes zu legen. Hierbei bestehen die gleichen bereits dargestellten Mängel.It is known in pressed carbon plates for galvanic elements to provide a cavity for receiving the electrolyte and a special insulating frame to lay on the protruding edges of this space created in this way. Here exist the same defects already presented.

Die Abb. i und 2 zeigen beispielsweise einen Preßkörper, der nach dem neuen Verfahren hergestellt ist.Figs. I and 2 show, for example, a pressed body that after the new process is produced.

In Abb. i ist mit g die Graphitschicht, mit b .die Braunstei.nschicht, mit c der Elektrolytraum bezeichnet. Der Isolierrahmen i. aus Isoliermaterial wird in einem Arbeitsgang' d. h. beim Pressen der Schicht g und b hergestellt, so daß der Raume zum Einfüllen des Elektrolyts noch offen bleibt.In Fig. I, g is the graphite layer, b is the brown stone layer, with c denotes the electrolyte space. The insulating frame i. from insulating material in one step 'd. H. produced when pressing the layer g and b, so that the space for filling in the electrolyte still remains open.

Abb. 2 zeigt eine Ansicht des Preßkörpers, in der eine zum Einfüllen des Elektrolyten vorgesehene Öffnung f sichtbar ist.Fig. 2 shows a view of the compact, in which one is for filling of the electrolyte opening f is visible.
