Abstract

The lead-acid accumulator has one or more cells where the conductor grids in the negative electrodes contain a metal with a higher conductivity than lead and which in the electro-chemical series is more positive than lead and/or in the positive electrodes contain a metal which is more negative than lead. During the discharge of the accumulator the terminal voltage and/or at least a single potential is continuously measure against a reference electrode. The discharge is interrupted at such a terminal voltage or at such an electrode potential so that no damaging quantities of the other metal are emitted from the electrode grid. The discharge may also be interrupted just before the emission of the other metal from the electrode grid occurs.

Description

Verfahren beim Betrieb von Bleiakkumulatoren Die Erfindung bezieht sich auf ein Verfahren beim Betrieb von Bleiakkumulatoren, die aus einer oder aus mehreren Zellen bestehen können, und bei denen die Elektrodengitter in den negativen und/oder postiven Elektroden ein anderes Metall als Blei oder eine Bleilegierung enthalten. Dieses andere Metall kann in Form einer Einlage oder als Legierungsbestandteil vorliegen. Hierbei sind diese anderen Metalle in der elektrochemischen Spannungskette bezüglich der negativen Elektroden positiver als Blei und bezüglich den positiven Elektroden negativer als Blei. Method in the operation of lead-acid batteries The invention relates refer to a procedure in the operation of lead-acid batteries that are made up of or from several cells can exist, and in which the electrode grid in the negative and / or positive electrodes a metal other than lead or a lead alloy contain. This other metal can be in the form of an insert or as an alloy component are present. Here these other metals are in the electrochemical voltage chain more positive than lead with respect to the negative electrodes and with respect to the positive electrodes Electrodes more negative than lead.

Die Elektrodengitter von Bleiakkumulatoren erfüllen zwei Funktionen.The electrode grids of lead-acid batteries fulfill two functions.

Einmal sollen sie dem aktiven Material als Trägergerippe dienen, und zum anderen sollen die Leiter für den elektrischen Strom darstellen. Aufgrund der begrenzten elektrischen Leitfähigkeit des Bleis entsteht in den Elektrodengittern ein gewisser Spannungsabfall, so daß der Wunsch nach Verwendung von Elektrodengittern besteht, die ganz oder teilweise aus Material mit besserer Leitfähigkeit bestehen.On the one hand, they should serve as a supporting framework for the active material, and on the other hand, the conductors are supposed to represent the electrical current. Due to the The limited electrical conductivity of the lead is created in the electrode grids a certain voltage drop, so that the desire to use electrode grids consists wholly or partially of material with better conductivity.

Hierbei ist es natürlich, daß man Metalle verwendet, die üblicherweise als elektrische Leiter benutzt werden, beispielsweise Kupfer und Aluminium.Here it is natural to use metals that are customary be used as electrical conductors, for example copper and aluminum.

Sowohl Kupfer als auch Alumin ium ist bereits bei Bleiakkumulatoren zur Anwendung gelangt. Beim Kupfer ist es erforderlich, dieses mit einem Uberzug aus Blei zu versehen, um einen direkten Kontakt zwischen dem Kupfer und dem Schwefelsäureelektrolyten zu unterbinden. Das Kupfer ist deshalb bisher in Teilen mit größeren Abmessungen, wie Polbrücken und dergleichen zur Anwendung gekommen. Da Aluminium sich bei direktem Kontakt mit Schwefelsäure sofort auflöst, und KUpfer in Form von Kupferionen im Elektrolyten auf die Elektroden ausgefällt werden kann, was bei Bleibatterien sehr nachteilig ist, ist die Verwendung eines anderen Metalles zusammen mit Blei in Elektrodengittern nur in sehr beschränktem Umfange möglich gewesen.Both copper and aluminum are already in lead-acid batteries is applied. In the case of copper, it is necessary to coat it made of lead to ensure direct contact between the copper and the sulfuric acid electrolyte to prevent. The copper is therefore so far in parts with larger dimensions, such as pole bridges and the like are used. Since aluminum is in direct Contact with sulfuric acid dissolves immediately, and copper in the form of copper ions in the Electrolytes can be precipitated on the electrodes, which is very common with lead-acid batteries The disadvantage is the use of a different metal together with lead in electrode grids was only possible to a very limited extent.

Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, bei der die Verwendung dieses anderen Metalls zusammen mit Blei in einem großeren Umfange möglich ist, ohne daß die vorerwähnten Nachteile auftreten, und bei der die Elektrodengitter eine verbesserte Leitfähigkeit als bisher besitzen.The invention is based on the object of creating a possibility when using this other metal together with lead in a larger one Scope is possible without the aforementioned disadvantages occurring, and in the the electrode grids have an improved conductivity than before.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei der Entladung des Akkumulators die Klemmenspannung der Batterie und/oder mindestens ein Einzelpotential gegen eine Bezugselektrode kontinuierlich gemessen wird, und die Entladung bei einer solchen Klemmenspannung oder einem solchen Elektrodenpotential unterbrochen wird, daß keine schädllichen Mengen des anderen Metalls aus den Elektrodengittern herausgelöst werden.According to the invention, this object is achieved in that during the discharge of the accumulator, the terminal voltage of the battery and / or at least one individual potential is measured continuously against a reference electrode, and the discharge at a such a terminal voltage or such an electrode potential is interrupted, that no harmful amounts of the other metal are released from the electrode grids will.

Ein weiteres 'merkmal kennzeichnet sich dadurch, daß die Entladung unterbrochen wird, bevor die Herauslösung des anderen Metalles beginnt.Another 'feature is characterized by the fact that the discharge interrupted before the dissolution of the other metal begins.

Durch die erfindungsgemäße kontinuierliche Messung der Klemmenspannung der Batterie während der Entladung bei einer vorher bestimmten Klemmenspannung wird erreicht, daß eine schädlich wirkende Herauslösung des anderen Metalles aus dem Blei nicht erfolgt, so daß dieses andere Metall in höherem Umfange als bisher bei Elektrodengittern verwendet werden und damit eine verbesserte Leitfähigkeit der Elektrodengitter erreicht werden kann.Due to the continuous measurement of the terminal voltage according to the invention the battery is discharged at a predetermined terminal voltage achieved that a detrimental leaching of the other metal the end the lead does not take place, so that this other metal to a greater extent than before used in electrode grids and thus improved conductivity the electrode grid can be reached.
