Description

Galvanisches Element mit Kohle-Braunstein-Elektrode. Es ist bekannt, bei Herstellung von galvanischen Elementen, vor allem Trockenbatterien, die Kohleelektrode, die einen Mantel aus einem Graphitbraunsteingemisch umgibt, mit einer Stoffschicht zu umhüllen, die das Graphitbraunsteingemisch zusammenhält. Es ist auch bekannt, diese Stoffschicht durch eine Hülle zu ersetzen, die aus einer gallertartigen Masse, welche aus mit Glycerin zusammengeschmolzener Gelatine, Wasser- und Salicylsäure hergestellt ist, besteht. Dieser Ersatz der Stoffhülle hat den Nachteil, daü der Zu "atz von Salicy lsäure die Gelatinemasse nur vor dem Verschimmeln schützt, sie aber nicht härtet oder gerbt und auch nicht gegen Feuchtigkeit unempfindlich macht, so daß die Feuchtigkeit des außerhalb der Hülle befindlichen Elektrolyts die Hülle auflöst und damit das Element zerstört.Galvanic element with carbon-manganese dioxide electrode. It is known, in the production of galvanic elements, especially dry batteries, the carbon electrode, which surrounds a jacket made of a graphite brown stone mixture, with a layer of fabric to encase that holds the graphite brownstone mixture together. It is also known to replace this layer of fabric with a cover made of a gelatinous mass, which consists of gelatine, water and salicylic acid melted together with glycerine is made, exists. This replacement of the fabric cover has the disadvantage that the The addition of salicylic acid only protects the gelatin from mold, it but does not harden or tan and also does not make it insensitive to moisture, so that the moisture of the electrolyte located outside the shell the shell dissolves and thus destroys the element.

Erfindungsgemäß wird, um die vorbeschriebenen Nachteile zu vermeiden, die Kohleelektrode mit einem Braunsteingraphitmantel in eine Masse getaucht, die aus einer Mischung von Gelatine mit Glycerin und Anilin besteht, die im Wasserbade gekocht und vor dem Erstarren mit Paraformaldehyd gehärtet bzw. gegerbt wird. Diese Masse hat den Vorteil, daü sie nach dem Erkalten erhärtet und gegen Feuchtigkeit unempfindlich ist. Der Elektrolyt wird der Masse zugesetzt. Will man den Elektrolyten für sich allein in den Batteriebehälter bzw. Zinkbecher gießen, so daü er durch die Massehülle vom Braunsteingraphitgemisch getrennt ist, dann darf man die Masse nur so schwach härten bzw. gerben, daß sie gerade noch die Feuchtigkeit des Elektrolyten hindurchläüt, aber nicht zerfällt.According to the invention, in order to avoid the disadvantages described above, the carbon electrode with a brown graphite coating is immersed in a mass, which consists of a mixture of gelatin with glycerine and aniline, which is placed in a water bath boiled and hardened or tanned with paraformaldehyde before solidification. These Mass has the advantage that it hardens after cooling and protects against moisture is insensitive. The electrolyte is added to the mass. Do you want the electrolyte Pour into the battery container or zinc jar by yourself, so that it goes through the mass shell is separated from the brownstone graphite mixture, then the mass is allowed cure or tan only so weakly that they still just absorb the moisture of the electrolyte runs through, but does not disintegrate.
