Description

Verfahren zur Herstellung von Akkumulator-Elektroden Die Erfindung bezieht sich auf die Herstellung von Elektroden für Akkumulatoren mit alkalischem Elektrolyten, die aus einer Anzahl von Behältern oder Rohren mit durchlochten Wandungen zur Aufnahme d er aktiven Masse bestehen, und bei denen zur Erhöhung der Leitfähigkeit Metallstreifen o. dgl. in die wirksame Masse eingebettet sind. Durch das Verfahren der Erfindung wird bezweckt, die Herstellung derartiger Elektroden zu vereinfachen und zu verbilligen. Man hat bereits Elektroden mit durchlochtem Metallbehälter für die aktive Masse und mit in der aktiven Masse eingebetteten Metallstreifen o. dgl. in der Weise hergestellt, daß die aktive Masse zunächst um die Metallstreifen o. dgl. hertungepreßt wurde und darauf in den I-Tetallbehälter eingelegt und dann mit dem Behälter zusammen zwecks Herstellung guten Kontaktes noch mal gepreßt wurde. Die. Pressung der aktiven Masse um die Metallträger erfordert besondere Formen und Vorrichtungen und einen besonderen Arbeitsgang.Process for the manufacture of accumulator electrodes The invention refers to the manufacture of electrodes for accumulators with alkaline Electrolytes consisting of a number of containers or tubes with perforated walls to take up the active material, and where to increase the conductivity Metal strips or the like are embedded in the effective mass. Through the procedure The aim of the invention is to simplify the manufacture of such electrodes and cheaper. You already have electrodes with perforated metal containers for the active mass and with metal strips or the like embedded in the active mass. manufactured in such a way that the active material first around the metal strips o. The like. Harness was pressed and then placed in the I-Tetall container and then with the container was pressed together again to establish good contact. The. Pressing the active material around the metal carrier requires special shapes and forms Devices and a special operation.

Um einen Arbeitsgang zu sparen und die Fabrikation zu vereinfachen, wird nach der Erfindung die Elektrode dadurch hergestellt, daß die aktive Masse und ein oder mehrere dünne Metallstreifen, Bänder oder Drähte zusammen, aber ohne vorherige Verbindung miteinander in den üblichen durchlochten Metallbehälter (z. B. in ein Rohr) hineingetan werden, worauf dieser in an sich bekannter Weise zusammengedrückt wird.In order to save an operation and to simplify the fabrication, according to the invention, the electrode is produced in that the active mass and one or more thin metal strips, bands or wires together but without prior connection with each other in the usual perforated metal container (e.g. B. in a tube), whereupon it is compressed in a manner known per se will.

Zweckmäßig wird dabei der Metallstreifen o-. dgl. so gelegt und geformt, daß er mit den Innenwänden des Behälters beim Preßvorgang in innige Berührung kommt. Der Metallstreifen kann die Form einer Schraube haben oder mehrfach umgebogen oder zickzackförmig umgelegt sein, so daß nicht nur die Kanten des Streifens sondern auch die Wendestellen des gebogenen Metallstreifens mit der Innenfläche der durchlochten Wände in Berührung stehen. Eine Ausführungsform der Elektrode, die nach dem Verfahren gemäß der Erfindung hergestellt wird', ist in der Zeichnung veranschaulicht. Die Elektrode besteht aus einem beispielsweise durch Walzen oder Pressen hergestellten trugartigen Teil A mit an den Seiten befindlichen Lappen AI. Eine Deckplatte B, die ebenfalls aus dünnem gelochten Metall besteht, wird dann auf den Teil A aufgelegt, wobei die Seitenenden Bl der Deckplatte über die Lappen A1 des Teils A übergreifen, so @daß ein Behälter in Form eines flachgedrückten Rohres mit durchlochten Vorder- und Rückwänden entsteht. Zusammen mit der aktiven Masse wird gemäß der Erfindung in dem Behälter A ein Metallstreifen C eingefügt, der mehrfach zickzackförmig umgebogen ist. Darauf wird der durchlochte Deckel B aufgelegt und das Ganze durch einen einzigen Preß.vorgang zu einer Elektrode vereinigt. Die Oberfläche des Streifens C liegt rechtwinklig zu den Vorder- und Rückwänden bzvv. dem Deckel und dem Boden des Behälters. Die einzelnen Biegungen des Streifens sind so bemessen, daß die Wendestellen an den Seitenwänden des Behälters anliegen, wie bei C'- angegeben ist. Weiterhin entspricht die Höhe des Streifens der Entfernung zwischen den Vorder- und Rückwänden des Behälters, so daß die Kanten des Streifens mit den Innenflächen dieser Wände in Berührung stehen.The metal strip is expediently o-. like so placed and shaped, that it comes into intimate contact with the inner walls of the container during the pressing process. The metal strip can have the shape of a screw or bent or multiple times be folded zigzag so that not only the edges of the strip but also the turning points of the bent metal strip with the inner surface of the perforated Walls are in contact. An embodiment of the electrode produced according to the method is manufactured according to the invention 'is illustrated in the drawing. the Electrode consists of one produced, for example, by rolling or pressing Wearing-like part A with flaps AI on the sides. A cover plate B, which also consists of thin perforated metal, is then placed on part A, the side ends B1 of the cover plate overlap over the tabs A1 of part A, so @ that a container in the form of a flattened tube with perforated front and back walls. Together with the active material is according to the invention A metal strip C inserted into the container A, which is bent over several times in a zigzag shape is. Then the perforated cover B is placed and the whole thing through a single one Pressing process combined into one electrode. The surface of the strip C lies at right angles to the front and rear walls or the lid and the bottom of the container. The individual bends in the strip are dimensioned so that the turning points rest against the side walls of the container, as indicated at C'-. Furthermore corresponds the height of the strip of the distance between the front and rear walls of the container, so that the edges of the strip are in contact with the interior surfaces of these walls.
