AKKUMÜLATORENGITTERPIATTEACCUMULATOR GRID

Die Erfindung bezieht sich auf Akkumulatorengitterplatten, insbesondere solche, die aus einer antimonarmen Bleilegierung bestehen.The invention relates to accumulator grid plates, in particular those made from a low-antimony lead alloy exist.

Vielfach bestehen Gitterplatten von Bleiakkumulatoren aus einer Legierung, die einen Antimonanteil von etwa 3,5 bis 11 Gewichtsprozenten aufweist. Solche Legierungen haben den Vorteil, ausreichende mechanische Festigkeit mit guten Gießeigenschaften zu vereinen. Andererseits jedoch bringen sie zahlreiche Probleme mit sich; so gelangt infolge der elektrochemischen Korrosion Antimon in die positiven und negativenOften there are grid plates of lead accumulators made of an alloy that has an antimony content of about 3.5 to 11 percent by weight. Such alloys have the advantage of having sufficient mechanical strength with good casting properties to unite. On the other hand, however, they pose numerous problems; so gets due to the electrochemical Corrosion antimony in the positive and negative

aktiven Massen; ausserdem tritt eine erhebliche Sulfatierung der Platten beim Lagern der Batterie auf. Ferner ist in der Nähe der negativen Platten die Wasserstoffüberspannung gering, da die aktive Masse mit von den positiven Platten stammendem Antimon verseucht ist, und die negativen Gitter weisen ebenfalls eine geringe Überspannung auf. Daraus ergibt sich einerseits ein hoher Elektrolytverbrauch, wenn die Batterie bei konstanter Spannung überladen wird, und andererseits eine rasche Selbstentladung dieser Batterie.active masses; there is also considerable sulfation of the plates when storing the battery. Furthermore, the hydrogen overvoltage is low in the vicinity of the negative plates, since the active mass is contaminated with antimony derived from the positive plates, and the negative grids also point a small overvoltage. On the one hand, this results in a high electrolyte consumption when the battery is at constant Voltage is overcharged, and on the other hand a rapid self-discharge of this battery.

Die Erfindung will eine Gitterplatte herstellen, mit der die Nachteile von Platten aus stark antimonhaltigen Legierungen vermieden werden, während gleichzeitig im Rahmen des Möglichen deren Vorteile beibehalten bleiben.The invention aims to produce a grid plate with which the disadvantages of plates made of alloys with a high content of antimony should be avoided while at the same time maintaining their advantages as much as possible.

Gegenstand der Erfindung ist eine Akkuraulatorengitterplatte, die dadurch gekennzeichnet ist, daß sie neben Blei 1 bis 3,5% Antimon, 0,001% bis 0,2% Tellur, 0,01 bis 0,2% Arsen, 0,005 bis 0,05% Zinn enthält.The subject of the invention is a battery grid plate, which is characterized in that, in addition to lead, it contains 1 to 3.5% antimony, 0.001% to 0.2% tellurium, 0.01 to 0.2% arsenic, Contains 0.005 to 0.05% tin.

Ohne die oben festgelegten Zusatzmengen von Arsen, Tellur und Zinn wäre eine Legierung mit 2,5 bis 3,5% Antimon weich, eine Legierung mit 1 bis 2,5% Antimon sogar weich und spröde gleichzeitig. Mit Tellurzusätzen von 0,001 bis 0*2%, je nach Antimongehalt, können die Gefahr der Rissbildung der Legierung vermieden und ihre Mechanischen Eigenschaften wie beispielsweise Härte, Biege- und Zugfestigkeit verbessert werden. Der Zusatz von Zinn steigert die guten Giesseigenschafiten der Legierung, und der Arsensusats sorgt für eine weitere Verbesserung der mechanischen. Eigenschaften.Without the added amounts of arsenic, tellurium and tin specified above, an alloy with 2.5 to 3.5% antimony would be soft, an alloy with 1 to 2.5% antimony is even soft and brittle at the same time. With tellurium additions from 0.001 to 0 * 2%, each depending on the antimony content, the risk of the alloy cracking can be avoided and its mechanical properties such as hardness, flexural strength and tensile strength improved. The addition of tin increases the good casting properties of the alloy, and the arsenic substitute provides a further improvement the mechanical. Properties.

In einer bevorzugten Ausführungsform werden für die positiven und negativen Gitterplatten Bleilegierungen vorvendet, die folgende Bestandteile aufweisen:In a preferred embodiment, for the positive and negative grid plates use lead alloys, which have the following components:

Antimon: 1%Antimony: 1%

Tellur : 0,1%Tellurium: 0.1%

Arsen ι 0,08%Arsenic 0.08%

Zinn : 0,03%Tin: 0.03%

2. Beispiel2nd example

Antimon: 2%Antimony: 2%

Tellur ι 0,075%Tellurium ι 0.075%

Arsen : 0,08%Arsenic: 0.08%

Zinn : O,O3%Tin: O, O3%

3. Beispiel3rd example

Antimon: 2,5%Antimony: 2.5%

Tellur : 0,001%Tellurium: 0.001%

Arsen : 0,05 bis 0,08%Arsenic: 0.05 to 0.08%

Zinn : O,03%Tin: 0.03%

Für positive Gitterplatten und insbesondere für Fahrzeug- und Seraifixbatterien kann Silber in Höhe von 0,02 bis 0,3% zugesetzt werden, um die elektrochemische Korrosion zu mindern. So kann vorteilhafterweise folgende Legierung verwendet werden:For positive grid plates and especially for vehicle and Seraifix batteries, silver in the amount of 0.02 up to 0.3% can be added to reduce electrochemical corrosion. The following alloy can advantageously be used will:

Antimon: 2,5% Tellur : 0,001% Arsen : 0,05 bis 0,08% Zinn : 0,03% Silber : 0,10 bis 0,13%Antimony: 2.5% Tellurium: 0.001% Arsenic: 0.05 to 0.08% Tin: 0.03% Silver: 0.10 to 0.13%

509839/0940 ./.509839/0940 ./.

Es wurde gemessen, daß ein aus vorstehender Legierung gefertigtes Gitter weniger auf elektrochemische Korrosion zurückzuführende Gewichtsverluste aufwies als ein Gitter, das aus einer herkömmlichen Legierung mit 6% Antimon und 0,13% Silber hergestellt war.It was measured that a grid made of the above alloy was less due to electrochemical corrosion There was weight loss as a grid made from a conventional alloy with 6% antimony and 0.13% silver was made.

In Versuchen konnte nachgewiesen werden, daß eine erfindungsgemäße Legierung gute Gießeigenschaften für das Ausformen von dünnen Gittern aufwies und daß diese Gitter ausreichende Härte und mechanische Zugfertigkeit besaßen. Um jedoch zusätzlich die Härte der Gitter zu erhöhen, ist es möglich, sie einer ergänzenden Wärmebehandlung zu unterziehen, beispielsweise, indem sie nach dem Ausformen in Wasser getaucht werden.Tests have shown that an alloy according to the invention has good casting properties for shaping of thin grids and that these grids had sufficient hardness and mechanical tensile strength. To however In addition to increasing the hardness of the grids, it is possible to subject them to additional heat treatment, for example, by immersing them in water after they have been molded.

Es läßt sich bei Batterien mit Gittern aus erfindungsgemäßen Legierungen feststellen, daß die Antimonverschmutzung der positiven und negativen Platten und die Wasserstoffabscheidung schwächer sind, als bei bisher bekannten Batterien. Die Ladeschlußspannung liegt wesentlich höher sowohl bei neuen als auch bei gebrauchten Batterien. Der Elektrolytverbrauch ist herabgesetzt, und bei Starterbatterien ist es nicht notwendig, während ihrer Lebensdauer Wasser nachzufüllen, ohne daß es jedoch erforderlich wäre, die Elektrolytreserve zu vergrößern; auch ist die Konservierung der Ladung während einer Lagerzeit von mehreren Monaten deutlich verbessert.It can be found in batteries with grids made of alloys according to the invention that the antimony contamination the positive and negative plates and the hydrogen separation are weaker than with previously known batteries. the The end-of-charge voltage is much higher for both new and used batteries. The electrolyte consumption is and starter batteries do not need to be topped up with water during their service life, but without it it would be necessary to increase the electrolyte reserve; also is the preservation of the cargo during a storage period significantly improved over several months.

Selbstverständlich ist die Verwendung der erfindungsgemäßen Legierung nicht auf die Herstellung von Gittern der vorgenannten Batterietypen beschränkt.Of course, the use of the alloy according to the invention does not apply to the production of grids aforementioned battery types are limited.
