Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Bei Röhrenelektroden für Akkumulatoren wird die Rohrwandung durchlocht, damit der Elektrolyt besser an die in den Röhren enthaltene aktive Masse herangelangen kann.In the case of tube electrodes for accumulators, the tube wall is perforated so that the Electrolyte can better get to the active mass contained in the tubes.

Werden die Löcher der Rohrwandung solcher Elektroden mit der aktiven Masse ausgefüllt, so erhöht das den inneren Widerstand solcher Akkumulatoren.If the holes in the pipe wall of such electrodes are filled with the active material, this increases the internal resistance such accumulators.

Um diesen Nachteil zu vermeiden, werdenTo avoid this disadvantage, be

ίο nach der Erfindung die Öffnungen vor dem Einfüllen der losen, pulvrigen aktiven Masse von innen mit Papier o. dgl. abgedeckt. Die fertig gefüllten Röhren bzw. Akkumulatoren werden dann in eine Flüssigkeit gebracht, welche die aktive Masse erhärtet, z. B. in verdünnte Schwefelsäure, Glyzerin o. dgl. Nach dem Trocknen wird dann der Akkumulator formiert. Während der Formierung und der ersten Ladungen zerfällt das Papier o. dgl, so daß dann die Löcher ganz offen bleiben.ίο according to the invention, the openings before Filling in the loose, powdery active material from the inside with paper or the like. Covered. the completely filled tubes or accumulators are then placed in a liquid, which hardens the active material, e.g. B. in dilute sulfuric acid, glycerine o. The like. After The accumulator is then formed after drying. During the formation and the The paper or the like disintegrates with the first charges, so that the holes then remain completely open.

Der Zerfall des Papiers kann durch Verwendung schwerer Säure beschleunigt werden.The disintegration of the paper can be accelerated by using heavy acids.

Patent-Ansprüche:Patent Claims: ι. Verfahren zur Herstellung perforierter röhrenförmiger Elektroden für Akkumulatoren, dadurch gekennzeichnet, daß die Öffnungen der Röhren vor dem Einfüllen der aktiven Masse innen mit Papier abgedeckt werden, welches bei. der Inbetriebsetzung des Akkumulators, d. h. nach der Erhärtung der Masse, zerfällt.ι. Process for the production of perforated tubular electrodes for accumulators, characterized in that the openings of the tubes prior to filling the active material must be covered inside with paper, which is at. commissioning of the accumulator, d. H. after the mass has hardened, disintegrates. 2. Verfahren nach Anspruch i, dadurch gekennzeichnet, daß der Akkumulator anfänglich mit für den normalen Gebrauch zu schwerer Säure gefüllt wird, um den Zerfall des Papiers zu beschleunigen.2. The method according to claim i, characterized in that the accumulator is initially filled with acid that is too heavy for normal use in order to accelerate the disintegration of the paper.
