Der Ansatz 14 schmilzt, und das geschmolzene Material fließt durch das Gitter 13 in die Poren der Lage 11, wodurch bei Abkühlung eine Verbindung zwischen der Lage 11, dem Gitter 15 und dem Rahmen entsteht.elongated loop is formed, is placed between the layer 11 and the frame 12, and then ultrasonic energy is applied to the approach 14 applied by the layer 11 and the grid 13 while Pressure between the layer 11 and the frame 12 is exerted. Of the Approach 14 melts, and the molten material flows through the grid 13 into the pores of the layer 11, thereby cooling down a connection between the layer 11, the grid 15 and the frame arises.

Im oben beschriebenen Verfahren bildet der Rahmen 12 den halben Zellenrahmen einer Luftelektrode einer primären Metall/Luft-Bat- f terie, und er ist mit einem in der Mitte liegenden Loch 15 versehen. Venn die Verbindung zwischen der Lage 11 und dem Rahmen 12 hergestellt worden ist, wird das aktive Material der Luftelektrode auf das Gitter 15 gegeben, und ein poröses isolierendes Trennstück (nicht dargestellt) wird in das Loch 15 gesetzt, um das aktive Material am Gitter 13 zu halten. Das Gitter 15 dient zum Tragen des aktiven Materials der Luftelektrode und wirkt als ein Dtromkollektor in der fertigen Batterie.In the method described above, the frame 12 forms half the cell frame of an air electrode of a primary metal / air battery terie, and it is provided with a hole 15 in the middle. When the connection between the sheet 11 and the frame 12 has been made, the active material becomes the air electrode placed on the grid 15, and a porous insulating separator (not shown) is placed in the hole 15 to the active To hold material on the grid 13. The grid 15 is used for carrying of the active material of the air electrode and acts as a current collector in the finished battery.

In einer Abwandlung (nicht dargestellt) des vorstehend beschriebenden Ausführungsbeispiels wird das aktive Material der Luftelektrode auf das Gitter 13 gegeben, ehe die Lage 11 mit dem Rahmen g 12 verbunden wird, wobei der Verbindungsvorgang auch dazu dient, das isolierende Trennstück am aktiven Material und zwischen dem Rahmen 12 und der Lage 11 zu halten.In a modification (not shown) of the embodiment described above, the active material of the air electrode is placed on the grid 13 before the layer 11 is connected to the frame g 12, the connecting process also serving to the insulating separator on the active material and between the frame 12 and the layer 11 to hold.

Polytetrafluoräthylen-Lage verwendet werden bzw. wird, die über eine verbundene Geite des Hahmens gefaltet wird, wobei die Lage oder die Lagen mit angebrachten Gittern versehen ist bzw. sind und eine Beschichtung mit dem aktiven Material vorgesehen ist.Polytetrafluoroethylene layer can be used, which is folded over a connected Geite of the frame, wherein the layer or layers is or are provided with attached grids and a coating with the active material is provided .

In einem zweiten Ausführungsbeispiel der Erfindung gemäß Fig. 3 und 4 muß eine Zelle einer primären Metall/Luft-Batterie hergestellt werden, wobei die Zelle zwei Luftelektroden aufweist, die auf gegenüberliegenden Seiten einer Hetallanode 16 sitzen und ihr gegenüber isoliert sind und jeweils aktives Haterial 17 aufweisen, das auf einem porösen Polytetrafluoräthylen-Träger getragen ist. Die Zelle wird dadurch hergestellt, daß eine Lage des aktiven Haterials 17 auf einen porösen Polytetrafltioräthylen-Ctreifen 18 gelegt wird, und dann wird das aktive Haterial 17 Eiit einem Streifen 19 aus einem porösen, isolierenden, schweißfähigen Katerial belegt, das im wesentlichen die gleichen Abmessungen wie der Streifen 18 hat. Der Streifen 19 wird vorzugsweise in der Form eines porösen Polyamids verwendet, das unter dem ¥arennakmen "BOlTDIIiA" zu erhalten ist. Die Metallanode 16 wird dann auf den Streifen 19 gelegt, und der Streifen 18 wird um seine Mittellinie herum gefaltet, derart, daß die Anode 16 zwischen gefalteten Partien des Ctreifens 19 eingefangen wird, wobei durch Stromzuführungen 21 bzw. 22 elektrische Verbindungen mit der Anode 16 bzw. mit dem aktiven Haterial 17 hergestellt werden. Ferner wird ein herausnehmbarer Stift 24 auf den Streifen 19 an der Anode 16 gelegt, derart, daß er sich parallel zu den Stromzuführungen 21, 22 erstreckt und über den Rand der Streifen 18 und 19 vorsteht. Die Zelle wird dann durch Herstellung einer flüssigkeitsdichten Verbindung zwischen den gefalteten Partien des Streifens 18 versiegelt, wobei sich die Verbindung um die Metallanode 16 herum erstreckt, wie das durch die Linien 25 in Fig. 4 angezeigt ist. Die Versiegelung entsteht durch TTltraschallverschweißen, das ein Schmelzen einer Partie des schweißfähigen Streifens 19 bewirkt, wobei die geschmolzene Partie in die Poren des Polytetrafluoräthylen-Streifens 18 fließt, so daß bei Ab- In a second embodiment of the invention according to FIGS. 3 and 4, a cell of a primary metal / air battery has to be produced, the cell having two air electrodes which are seated on opposite sides of a metal anode 16 and are insulated from it and in each case active material 17 have, which is carried on a porous polytetrafluoroethylene support. The cell is made by laying a layer of the active material 17 on a porous polytetrafluoroethylene strip 18 and then overlaying the active material 17 with a strip 19 of porous, insulating, weldable material having substantially the same dimensions like the strip 18 has. The strip 19 is preferably used in the form of a porous polyamide, which is available under the name "BOlTDIIiA". The metal anode 16 is then placed on the strip 19 and the strip 18 is folded about its center line so that the anode 16 is trapped between folded portions of the strip 19, with electrical connections to the anode 16 through power leads 21 and 22, respectively or with the active material 17 are produced. Furthermore, a removable pin 24 is placed on the strip 19 on the anode 16 in such a way that it extends parallel to the power supply lines 21, 22 and protrudes over the edge of the strips 18 and 19. The cell is then sealed by making a liquid-tight connection between the folded portions of the strip 18, the connection extending around the metal anode 16 as indicated by lines 25 in FIG. The seal is created by ultrasonic welding, which causes a portion of the weldable strip 19 to melt, the melted portion flowing into the pores of the polytetrafluoroethylene strip 18 so that when

kühlung eine flüssigkeitsdichte Versiegelung zwischen den gefalteten Partien des Streifens 18 entsteht. Der Stift 24 wird dann aus der Zelle herausgezogen, damit ein Zugang zu der Zellenkammer entsteht, die innerhalb der versiegelten Partie des Streifens gebildet ist, so daß ein Elektrolyt eingegeben werden kann.cooling creates a liquid-tight seal between the folded Parts of the strip 18 arise. The pin 24 will then pulled out of the cell to allow access to the cell chamber formed within the sealed portion of the strip so that an electrolyte can be added.

Es versteht sich, daß andere Verfahren zum Verschweißen außer das TTltraschallverschweißen verwendet werden können, um das schweißfähige Haterail in den vorstehend beschriebenen Beispielen zum Schmelzen zu bringen. Ferner versteht es sich, daß zwar in den vor- ^ stehenden Beispielen Polytetrafluorethylen verwendet wird, bei dem es sich um ein poröses, nicht-schweißfähiges, hydrophobes Kunstharz handelt, das derfindungsgemäße Verfahren aber auch zur Verbindung zweier Teile verwendet werden kann, bei denen eines aus einem porösen Kunstharz besteht, bie§pielsweise PVC, das sowohl schweißfähig als auch nicht-hydrophob ist, vorausgesetet, daß der Schmelzpunkt des anderen Teils unter dem des porösen Kunstharzes liegt. Entsprechend können auch poröse, nicht-schweißfähige, hydrophobe Kunstharze außer Polytetrafluorethylen verwendet werden.It will be understood that methods of welding other than ultrasonic welding can be used to create the weldable Melting Haterail in the examples described above. Furthermore, it goes without saying that although in the previous ^ Examples of polytetrafluoroethylene is used, in which it is a porous, non-weldable, hydrophobic synthetic resin acts, the inventive method but also for connection two parts can be used, in which one consists of a porous synthetic resin, e.g. PVC, which is both weldable as well as non-hydrophobic, provided that the melting point the other part is lower than that of the porous synthetic resin. Correspondingly, porous, non-weldable, hydrophobic Synthetic resins other than polytetrafluoroethylene can be used.
