Description

Die Erfindung betrifft einen Akkumulator. Der Erfindung· gemäß ist bei einem Akkumulator mit einer durch, den Elektrolyten unangreifbaren Kathode an der Anode immer ein Überschuß von Halogenen vorhanden zu dem Zweck, das Zink ο. dgl. beim Entladen vollständig von der Kathode zu entfernen. The invention relates to an accumulator. According to the invention is in an accumulator with a cathode on the anode that cannot be attacked by the electrolyte an excess of halogens is present for the purpose of making the zinc ο. Like. When unloading completely removed from the cathode.

Es sind Akkumulatoren in vielfacher Ausführung bekannt, bei denen sich beim Laden an der Anode Halogene entwickeln und Zink ο. dgl. an der Kathode abgeschieden werden. Bei diesen Akkumulatoren lagert sich im Laufe der Zeit durch. Laden und Entladen dauernd Zink ο. dgl. an der Kathode ab, welches beim Entladen nicht restlos wieder von derselben entfernt wird, sondern eine ungleichmäßig anwachsende Ablagerung bildet.There are accumulators known in multiple designs, in which when charging Halogens and zinc ο develop at the anode. Like. Be deposited on the cathode. These accumulators accumulate over time. Loading and unloading permanent zinc ο. Like. At the cathode, which is not completely restored when discharging is removed from the same, but forms an unevenly growing deposit.

Der Akkumulator gemäß Erfindung zeigt den Vorteil, daß diese Nachteile dadurch vermieden werden, daß beim vollständigen Entladen der Niederschlag von Zink ο. dgl. vollständig wieder von der Kathode entfernt wird. Zur Erreichung dieses Zweckes besitzt der Akkumulator eine Anode, an der immer ein Überschuß von Halogenen vorhanden ist, so daß dadurch beim Entladen das Metall vollständig von der Kathode entfernt wird.The accumulator according to the invention has the advantage that these disadvantages thereby it is avoided that the precipitation of zinc ο during complete discharge. like is completely removed again from the cathode. To achieve this, owns the accumulator has an anode, on which there is always an excess of halogens, so that when discharging the metal is completely removed from the cathode.

Das Vorhandensein eines dauernden Über-Schusses von Halogen an der Anode wird dadurch erreicht, daß die Anode in dem Akkumulator in teilweise geladenem bzw. formiertem Zustand zur Verwendung kommt, d.h. daß dieselbe entweder vor dem ersten Laden des Akkumulators bereits geladen oder formiert wurde und sich dabei bereits mit Halogenen assoziiert hat, die für immer mit der Anode verbunden bleiben und derselben beim späteren Gebrauch in dem Akkumulator ein dauerndes Übermaß von Halogen verleihen, durch das das Zinko. dgl. beim Entladen immer restlos von der Kathode entfernt wird, oder daß dem Elektrolyten ein Übermaß von Bromin hinzugefügt wird, welches sich mit dem Zink bei der ersten Entladung so verbindet, daß ein Betrag von Brom, der der niedergeschlagenen Zinkmenge äquivalent ist, in der Anode verbleibt. Da das Brom in dem Elektrolyten sich mit der äquivalenten niedergeschlagenen Zinkmenge während der ersten Entladung verbindet, ist immer ein Überschuß von Halogen vorhanden. Wesentlich ist, daß die Kathode aus einem durch den ElektrolytenThe presence of a permanent over-shot of halogen at the anode is achieved in that the anode in the accumulator is partially charged or formed state is used, i.e. that it either before the first Charging the accumulator has already been charged or formed and is already doing this associated with halogens that remain forever associated with the anode and the same give a permanent excess of halogen in later use in the accumulator, through which the zinco. like is always completely removed from the cathode when discharging, or that the electrolyte an excess of bromine is added, which combines with the zinc on the first discharge so that an amount of bromine equivalent to the amount of zinc deposited remains in the anode. Because the bromine in the electrolyte is the equivalent amount of zinc precipitated during the first discharge connects, there is always an excess of halogen. It is essential that the Cathode from a through the electrolyte

unangreifbaren Material besteht und eine Oberfläche bildet, die der Kathode eine wesentliche Wasserstoffüberspannung gibt. Die letztere Eigenschaft ist wünschenswert, jedoch nicht unbedingt erforderlich.invulnerable material and forms a surface that the cathode a there is substantial hydrogen overvoltage. The latter property is desirable but not absolutely necessary.

Die Kathode ist entweder mit einer glattpolierten oder mit einer rauhen Oberfläche versehen, die mit einem Quecksilber film verbunden ist. Als geeignetes Material für die ίο zu verwendende Kathode dient vorzugsweise eine Siliciumeisenlegierung, Graphit o. dgl.The cathode is either with a smoothly polished or with a rough surface provided, which is connected to a mercury film. As a suitable material for the The cathode to be used is preferably a silicon iron alloy, graphite or the like.
