  Verfahren zur Herstellung von dünnen Kohleplatten und   KohleMelektrodeu   für Bielektroden galvanischer Elemente. 



   Es ist bekannt, dass man aus Kohlegraphitpulver durch Pressen und   eventuelles Glühen im Muffel-   ofen dünne Platten für galvanische Elemente herstellen kann. Nach diesem Verfahren hergestellte Kohleplatten haben den Nachteil, dass sie äusserst spröde sind und bei geringer   mechanischer     Beanspruchung   zerbrechen. Besonders bei zirka 1 mm und darunter liegenden Wandstärken der Platten, wie sie für galvanische Elemente mit plattenförmigen Elektroden   erwünscht   sind. können durch diesen Nachteil nur schwer und sehr teuer hergestellt werden. 



   Vorliegende Erfindung betrifft ein bei   Vermeidung   obiger Nachteile vereinfachtes und verbilligtes Verfahren zur Herstellung von dünnen elastischen Kohleplatten mit hoher Leitfähigkeit. Im wesentlichen besteht das den   Patentansprüchen   zugrunde liegende Verfahren darin, dass man auf eine geeignete saugfähige Unterlage, welche aus Papier. Leinen. Cellulosederivaten u. dgl. bestehen kann, die man vorher mit einem Binde- oder Klebemittel imprägniert hat, Kohlegraphitpulver durch Einpressen oder Aufwalzen aufbringt. Solcherart hergestellte Kohleplatten weisen selbst bei geringer unter   1 mm   liegender Wandstärke grosse Stabilität und gute Leitfähigkeit auf. Je nach dem Verwendungszweck kann man auf die Unterlage das Kohlegraphitpulver ein-oder beiderseitig aufpressen.

   Bei bielektrodaler Ausbildung der Kohleplatte ist es vorteilhaft, auf eine Seite der Unterlage das Kohlegraphitpulver und auf der Rückseite gleichzeitig eine Isolierschicht aufzupressen, so dass die Kohleplatte gegen das Zinkblech, mit dem es durch Umbiegen der Enden des Bleches leitend verbunden wird, isoliert ist.

  Process for the production of thin carbon plates and carbon electrodes for metal electrodes of galvanic elements.



   It is known that thin plates for galvanic elements can be produced from carbon graphite powder by pressing and possibly annealing in a muffle furnace. Carbon plates produced according to this process have the disadvantage that they are extremely brittle and break with little mechanical stress. Especially with a wall thickness of approximately 1 mm and below that of the plates, as desired for galvanic elements with plate-shaped electrodes. can be produced only with difficulty and very expensive due to this disadvantage.



   The present invention relates to a simplified and cheaper method for producing thin, elastic carbon plates with high conductivity while avoiding the above disadvantages. Essentially, the method on which the claims are based consists in placing one on a suitable absorbent pad made of paper. Linen. Cellulose derivatives u. Like. Can exist that has previously been impregnated with a binder or adhesive, carbon graphite powder is applied by pressing or rolling. Carbon plates produced in this way have great stability and good conductivity even with a wall thickness of less than 1 mm. Depending on the intended use, the carbon graphite powder can be pressed onto one or both sides of the base.

   In the case of a bi-electrodal design of the carbon plate, it is advantageous to press the carbon graphite powder onto one side of the base and at the same time an insulating layer on the back so that the carbon plate is insulated from the zinc sheet, to which it is conductively connected by bending the ends of the sheet.
