Description

Galvanisches Element Es ist bekannt, der Depolarisationsmasse galvanischer Elemente Ruß zuzusetzen, welcher durch Spaltung von Gasen gewonnen wird.Galvanic element It is known that the depolarization mass is galvanic Adding elements soot, which is obtained by splitting gases.

Es wurde gefunden, daß erhebliche Vorteile erzielt werden, wenn man anstatt Ruß den bei der thermischen Zersetzung von Graphitoxyd entstehenden Kohlenstoff verwendet. Einerseits wird dadurch die Kapazität des galvanischen Elements wesentlich erhöht, anderseits wird auf Grund des fein verteilten Zustandes und des geringen Volumgewichts des Zersetzungsprodukts die Hälfte und weniger der sonst bei der Anwendung von Ruß üblichen Menge verbraucht. Auch die völlige Freiheit des Zersetzungsprodukts von unerwünschten fettigen und öligen Bestandteilen, die sonst gewöhnlich der Ruß enthält, wirkt sich für die Güte der Elemente günstig aus. Außerdem ist es vorteilhaft, daß das Zersetzungsprodukt ohne Schwierigkeit am Ort des Verbrauchers aus Graphitoxyd gewonnen werden kann, so daß anstatt des Zersetzungsprodukts auch das Graphitoxyd selbst verschickt werden kann, welches auf Grund seines höheren Raumgewichts einen wirtschaftlicheren Versand als bei Verwendung von Ruß ermöglicht. Es wird dann auch die Arbeit eingespart, welche sonst für die Auflockerung, Siebung usw. des gepreßten Rußes aufgewendet werden n.uß.It has been found that significant advantages can be obtained if one instead of soot, the carbon formed during the thermal decomposition of graphite oxide used. On the one hand, this increases the capacitance of the galvanic element increased, on the other hand, due to the finely divided state and the low Volume weight of the decomposition product is half and less than that otherwise in the application the usual amount of soot consumed. Also the complete freedom of the decomposition product of undesirable greasy and oily components, which are otherwise usually the soot contains, has a beneficial effect on the quality of the elements. It is also beneficial that the decomposition product from graphite oxide without difficulty at the consumer's place can be obtained, so that instead of the decomposition product, the graphite oxide can be sent by yourself, which due to its higher density is a allows more economical shipping than when using carbon black. It will then too saved the work that would otherwise be required for loosening, sieving, etc. of the pressed Soot are used n.uß.
