  Galvanisches Element. 



   Die Erfindung betrifft ein galvanisches Element, das insbesondere als Trockenelement geeignet ist. Das Element, kann als Leiter erster Ordnung Zink und Kohle, als Depolarisator Braunstein mit oder ohne Zusatz von Graphit besitzen, wie die bekannten LeelancheElemente und viele bekannte Trockenelemente. Als Leiter zweiter Ordnung dient gemäss der 
 EMI1.1 
 da es nicht hygroskopisch ist und im trockenen Zustand weder den Depolarisator noch die Leiter erster Ordnung, insbesondere das Zink nicht angreift, so kann das Element selbst in feuchter Luft lange Zeit lagern, ohne dass sich Spannung an den Klemmen zeigt und kann ohne Gefahr der   Kapazitätsverringerung   versandt werden. Will man das Element in Gebrauch 
 EMI1.2 
 Doppelchlorid löst, worauf das Element sofort wirksam ist. 



   Es ist schon vorgeschlagen worden, als Erreger für Elemente dieser Art mechanische Gemische von Ammoniumchlorid mit Chloriden eines oder mehrerer anderer Metalle, wie Magnesium oder Zink zu verwenden. Da indessen solche mechaniche Gemische von Chloriden im trockenen Zustand bekanntlich'hygroskopisch sind. so können sie zur Anfertigung lagerfähiger Trockenelemente nicht verwendet werden, ganz abgesehen davon, dass diese Chloride   beträchtliche Neigung   zur Bildung von wasserunlöslichen Oxychloriden zeigen. Dadurch, dass 
 EMI1.3 
 verwendet wird (ein wohlcharakterisiertes chemisches Individium), das von einem mechanischen Gemisch von innerhalb weiter Grenzen schwankender Zusammensetzung völlig verschieden ist, unterscheidet sich das vorliegende galvanische Element grundsätzlich von den oberwähnten bekannten Elementen. 



   Die bei vielen Trockenelementen bisher verwendeten Schutzstoffe. welche die Wasseraufnahme der hygroskopischen Erregersalze (Salmiak,   Zinkchlorid) verzögern sollen   (Traganth, Harze, kristallwasserhaltige indifferente Stoffe) werden dadurch entbehrlich und damit entfallen auch die mit der Verwendung dieser Zusätze verknüpften   Übeistände,   wie Erhöhung des Gewichtes und des inneren Widerstandes des Elementes und Verringerung seiner Haltbarkeit und Kapazität. 



     ) fit Hilfe   der Erfindung erreicht man übrigens auch eine höhere und konstantere   EMK. als   bei den bisherigen Elementen. bei welchen als Erregersubstanz einfache Chloride verwendet wurden.

  Galvanic element.



   The invention relates to a galvanic element which is particularly suitable as a dry element. The element can have zinc and carbon as a first-order conductor, and manganese dioxide as a depolarizer, with or without the addition of graphite, such as the well-known Leelanche elements and many well-known dry elements. According to the, serves as the head of the second order
 EMI1.1
 Since it is not hygroscopic and when dry does not attack either the depolarizer or the first-order conductors, in particular the zinc, the element can be stored for a long time even in moist air without tension being shown at the terminals and without the risk of reducing its capacity be shipped. One wants the element in use
 EMI1.2
 Double chloride dissolves, whereupon the element takes effect immediately.



   It has already been proposed to use mechanical mixtures of ammonium chloride with chlorides of one or more other metals such as magnesium or zinc as exciters for elements of this type. Since such mechanical mixtures of chlorides are known to be hygroscopic in the dry state. they cannot be used for the production of storable dry elements, quite apart from the fact that these chlorides show a considerable tendency to form water-insoluble oxychlorides. As a result of that
 EMI1.3
 is used (a well-characterized chemical individual), which is completely different from a mechanical mixture of composition fluctuating within wide limits, the present galvanic element differs fundamentally from the above-mentioned known elements.



   The protective substances previously used in many dry elements. which are supposed to delay the water absorption of the hygroscopic pathogen salts (salmiak, zinc chloride) (tragacanth, resins, indifferent substances containing water of crystallization) are thus dispensable and thus the additional measures associated with the use of these additives, such as increasing the weight and the internal resistance of the element and reducing it, are also dispensed with its durability and capacity.



     By the way, with the help of the invention, a higher and more constant emf can also be achieved. than with the previous elements. in which simple chlorides were used as the pathogen.



     PATEXT-AX SPHERE:
 EMI1.4
 non-hygroscopic double chloride of ammonium and a metal is used.
