Description

Galvanisches Element. Es ist bekannt, bei galvanischen Elementen die positiven Elektroden aus einer Braunsteingraphitmasse herzustellen, welche um einen Kohlenstab, der zur Ableitung des Stromes dient, herumgepreßt wird. Es ist unbedingt notwendig, daß die Teilchen der Masse unter sich und an dem Kohlenstab dicht und fest anliegen, um einen guten Kontakt zu erzielen und Spannungsverluste zu vermeiden. Nun hat es sich gezeigt, daß die zusammengepreßten Elektroden beim Feuchtwerden sich wieder lockern und der Kontakt stark beeinträchtigt wird.Galvanic element. It is known that the galvanic elements positive electrodes made of a brownstone graphite mass, which around a Coal rod, which serves to divert the current, is pressed around. It is absolutely necessary necessary that the particles of the mass under themselves and on the carbon rod close and to ensure good contact and avoid voltage loss. It has now been shown that the compressed electrodes become wet loosen again and the contact is severely impaired.

Die Erfindung hilft diesem Übelstand ab. Es hat sich gezeigt, daß man ein Zerfallen der gepreßten Braunsteingraphitmasse und infolgedessen eine Lockerung des Kontaktes dadurch fast vollständig verhindern kann; wenn man der Masse schwer lösliche organische Säuren zusetzt. Am besten eignen sich hierzu die organischen Säuren der Benzolreihe.The invention remedies this drawback. It has been shown that one disintegration of the pressed brownstone graphite mass and, as a result, loosening can thereby almost completely prevent contact; if you are heavy with the crowd adds soluble organic acids. The organic ones are best suited for this Acids of the benzene series.

Der Zusatz kann entweder zur Masse erfolgen oder aber zu dem Elektrolyten.The addition can either be made to the mass or to the electrolyte.

Der erwähnte Zusatz bewirkt auch, daß im Elektrolyten eine dauernde, konstante Wasserstoffionenkonzentration erhalten wird, wodurch ein langsameres Abfallen der elektromotorischen Kraft des Elementes bewirkt wird.The addition mentioned also has the effect that a permanent, constant hydrogen ion concentration is obtained, resulting in a slower decrease the electromotive force of the element is effected.
