Description
Negative Elektrode für elektrische Sammler Die Ertindung bezieht sich auf negative i:lel;troden für elektrische Sammler, bei w;_l-I hen die während des Ladens den Zinkniederschlag erhaltende Fläche in mehrere paralel untereinander und mit dem äußeren :-iromkreis verbundene Elemente unterteiltist.Negative electrode for electrical collectors The invention relates on negative i: lel; troden for electrical collectors, at w; _l-I hen the during the Store the zinc precipitate-receiving area in several paralel with each other and is divided into elements connected to the outer circle.
Der Zweck der Erfindung ist, eine Elek-;rode zu schaffen, bei welcher die Fläche zur Aufnahme des Zinkes durch eine mit parallelen Schlitzen versehene ltZ,ta'_lplatte gebildet wird. derart, daß die Elektrode aus roneinander unabhängigen Teilen besteht, deren Enden durch die Ränder der Platte miteinander verbunden sind. Die Ränder der Platte müssen dabei einen solchen Querschnitt haben. daß sie einen möglichst geringen. Widerstand bieten, um eine gleichförinige Verteilung des Stromes zu gewährleisten. Letzteres kann dadurch erreicht werden, daß die Ränder der Platte genügend breit oder dick gewählt werden, oder zweckmäßig dadurch, daß die Ränder mit den Seiten eines leitenden Rahmens in Eingriff gebracht werden, mit welchem der äußer, Stromkreis in Verbindung steht.The purpose of the invention is to provide an electrode in which the surface for receiving the zinc through one provided with parallel slots ltZ, ta'_lplatte is formed. in such a way that the electrodes are independent of one another Parts consists, the ends of which are connected to one another by the edges of the plate. The edges of the plate must have such a cross-section. that they are one as low as possible. Provide resistance to a uniform distribution of the current to ensure. The latter can be achieved in that the edges of the plate be chosen sufficiently wide or thick, or expedient in that the edges engaged with the sides of a conductive frame with which the external, circuit communicates.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und es ist: Abb. i eine Vorderansicht eines vollständigen Akkumulators gemäß der Erfindung mit abgenommener Stirnwand, Abb.2 eine Längsansicht des Innern des Akkumulators, Abb.3 eine Ansicht einer negativen Elektrode nach der Erfindung, Abb. .l ein Schnitt nach der Linie IV-IV der Abb.3, -Abb. S ein Schnitt nach der Linie V-V der Abb. 3 und Abb. b eine Ansicht des Trägers zur Aufnahme des Zinkniederschlages.The drawing shows an embodiment of the subject matter of the invention and it is: Fig. i a front view of a complete accumulator according to the invention with the front wall removed, Fig.2 is a longitudinal view of the interior of the accumulator, Figure 3 is a view of a negative electrode according to the invention, Fig. 1 a section along the line IV-IV of Fig. 3, - Fig. Sa cut after the Line V-V of Fig. 3 and Fig. B a view of the carrier for receiving the zinc precipitate.
Der auf der Zeichnung veranschaulichtr Akkumulator hat drei negative Elektroden t und zwei positive Elektroden 2, die aus Bleiplatten irgend geeigneter Art bestehen können und in welchen das aktive Material durch das Bleioxyd gebildet wird. Die Elektroden sind mit Trennorganen 3 in einem Behälter 4 untergebracht, der einen beispielsweise aus einer schwefelsauren Zink-Sulfat-Lösung mit oder ohne Zusatz von anderen Stoffen gebildeten Elektrolyten aufnimmt. Die negativen Elektroden i, die positiven Elektroden 2 und die Trennorgane 3 greifen mit ihren seitlichen Rändern in isolierende Nuten der Außenteile 5 ein.The accumulator illustrated in the drawing has three negative electrodes t and two positive electrodes 2, which can consist of lead plates of any suitable type and in which the active material is formed by the lead oxide. The electrodes are housed with separating bodies 3 in a container 4 having a sulfate solution of zinc with or without addition of substances other electrolyte formed on take t, for example, a sulfuric acid. The negative electrodes i, the positive electrodes 2 and the separating elements 3 engage with their lateral edges in insulating grooves in the outer parts 5.
Bei dem dargestellten Ausführungsbeispiel besteht jede negative Elektrode aus einer dünnen Metallplatte 6, beispielsweise Messing, die zweckmäßig versilbert und derart ausgeschnitten ist, daß parallele Streifen 7 stehen bleiben. Auf jedem Streifen 7 wird ein Stück Zink S angebracht. Das Ganze dieser Teile S bildet die aktive Fläche der Elektrode. Die so fertiggestellte Platte 6 wird mit ihren Rändern in einem dreiseitigen Gestellrahmen g derart eingeführt, daß die Streifen 3 eine wagerechte Lage einnehmen, sobald die Elektrode in dem Akkumulator ihre Arheitsstellung einnimmt. DerRahmeng weist zu diesem Zweck wenigstens an seinen Seitenwandungen innen Nuten auf, und seine Obere Seite ist mit einem Ansatz io versehen, an welchem das zum Anschluß des Leitungsdrahtes des äußeren Stromkreises dienende \Terbindungsstück i i angebracht ist.In the illustrated embodiment, there is each negative electrode from a thin metal plate 6, for example brass, which is expediently silvered and is cut out in such a way that parallel strips 7 remain. On every A piece of zinc S is attached to strip 7. The whole of these parts S forms the active area of the electrode. The thus finished plate 6 is with its edges in a three-sided frame g introduced in such a way that the Strip 3 assume a horizontal position as soon as the electrode is in the accumulator assumes their working position. For this purpose, the frame indicates at least its Sidewalls on the inside grooves, and its upper side is provided with a shoulder io, to which that serves to connect the lead wire of the external circuit \ Terbindungsstück i i is attached.
Infolge dieser Bauart wird jede negative Elektrode aus mehreren voneinander getrennren Elementen gebi.det, die unabhängig voneinander wirken und parallel in den Stromkreis eingeschaltet sind. Die Seiten des Rahmens g bieten dem Stromdurchgang einen solchen Querschnitt, daß die genaue Verteilung des Stromes über sämtliche parallel geschaltete Elemente stets gewährleistet wird.As a result of this construction, each negative electrode is made up of several of each other separated elements, which act independently of one another and in parallel in the circuit are switched on. The sides of the frame g provide the passage of current such a cross-section that the exact distribution of the current over all elements connected in parallel is always guaranteed.
