Description

Verfahren zur Herstellung von Elektroden für galvanische Elemente. Die Erfindung betrifft ein Verfahren zur Herstellung von Elektroden für galvanische Elemehte aus einem Gemisch von im wesentlichen Braunstein oder dessen Ersatz und Kohlenstoff, insbesondere Graphit. - Bisher wurden die Elektroden in der Weise hergestellt, daß man die genannten Stoffe einzeln am Herstellungsort dem Mahlverfahren unterwarf. Die Elementfabriken bezogen diese einzeln gemahlenen Stoffe aus den Ursprungsstätten, mischten sie in Mischtrommeln und preßten sodann das Gemisch.Process for the production of electrodes for galvanic elements. The invention relates to a method for producing electrodes for galvanic Elements made from a mixture of essentially brownstone or its substitute and Carbon, especially graphite. - So far the electrodes have been manufactured in such a way that one subjected the substances mentioned individually to the grinding process at the place of manufacture. The element factories obtained these individually ground substances from the places of origin, mixed them in mixing drums and then pressed the mixture.

Der Erfindung gemäß werden die Grundstoffe vor dem Mahlen gemischt und gemeinsam zu einer weitgehenden Feinheit, insbesondere im Naßmahlverfahren, . vermahlen. Dieses Verfahren hat den Vorteil, daß die Leistungsfähigkeit einer aus dem erzielten Material hergestellten Elektrode ganz erheblich vergrößert wird.According to the invention, the bases are mixed before milling and together to an extensive fineness, especially in the wet grinding process, . grind. This method has the advantage that the performance of a made of the material obtained is enlarged quite considerably.

Das Verfahren kann beispielsweise in folgender Weise durchgeführt werden Braunstein oder sein Ersatz und Graphit o. dgl., beide in der handelsüblichen größten Feinheit, werden gemischt und durch Wasserzusatz zu einem dünnen breiigen Zustand gebracht. Dem Brei können noch sonstige übliche Zusätze beigegeben werden.The method can be carried out, for example, in the following manner brownstone or its substitute and graphite or the like, both in the commercially available greatest fineness, are mixed and, by adding water, to a thin pulpy State brought. Other customary additives can be added to the pulp.

Dieses Gemisch wird in einer Exzenter-Graphitmühle gemahlen, und zwar wird es etwa viermal durchgemahlen, um eine ganz hervorragende Feinheit zu erzielen. Durch diese Behandlung wird eine bisher. unerreichte Homogenität der Mässe erzielt, die, wie der Versuch ergeben hat, für die Wikrung der aus der Masse hergestellten Elektroden von außerordentlichem Vorteil ist.This mixture is ground in an eccentric graphite mill, namely it is ground about four times to achieve a very fine fineness. Through this treatment one becomes so far. unmatched homogeneity of dimensions is achieved, which, as the experiment has shown, for the promotion of those made from the mass Electrodes is extremely beneficial.

So hat beispielsweise das feinere Vermahlen und die durch das gemeinschaftliche Vermahlen der Grundstoffe erzielte innigere und homogenere Verbindung der Grundstoffe eine erhöhte und auf längere Dauer gleichmäßige Sauerstoffabgabe zur Folge. Dieses zeigt sich in der erhöhten Leistung des mit der Elektrode ausgestatteten Elementes.So, for example, has the finer grinding and that through the communal Milling the raw materials achieved a closer and more homogeneous connection of the raw materials result in an increased and, over a longer period of time, even release of oxygen. This is shown in the increased performance of the element equipped with the electrode.

Die bessere Wirkung kann ohne Beigabe von Beimischungen erzielt werden, welche die Lebensdauer des Elementes beeinträchtigen.The better effect can be achieved without adding additives, which affect the service life of the element.
