Description

Die Erfindung betrifft eine negative Elektrode für Bleiakkumulatoren in Form einer aus Kupferstreckmetall bestehenden rechteckigen Gitterplatte, die als Träger für die aktive Masse und zur Stromzu- bzw. •abführung dient.The invention relates to a negative electrode for lead batteries in the form of one made of expanded copper metal existing rectangular grid plate, which serves as a carrier for the active mass and for power supply or • Discharge is used.

Bei einer bekannten negativen Elektrode dieser Art IBt eine Anschlußklemme an einer Ecke der rechteckigen Gitterplatte angeordnet. Durch die Verwendung von Kupferstreckmetall wird zwar unter Herabsetzung des Plattengewichtes eine gute elektrische Leitfähigkeit trzielt; die Stromleitfähigkeit ist jedoch bei der bekannten Elektrode noch nicht optimal. Insbesondere die Gleichmäßigkeit der Stromverteilung innerhalb der Elektrode läßt zu wünschen übrig (DE-OS 19 38 409).In a known negative electrode of this type IBt a terminal on a corner of the rectangular Arranged grid plate. Through the use of expanded copper metal is reduced the weight of the plate has good electrical conductivity tr aims; however, the conductivity of the known electrode is not yet optimal. In particular the uniformity of the current distribution within the electrode leaves something to be desired (DE-OS 19 38 409).

Das Ziel der vorliegenden Erfindung besteht somit darin, eine negative Elektrode für Bleiakkumulatoren der eingangs genannten Gattung zu schaffen, bei der die Stromleitfähigkeit optimiert ist.The aim of the present invention is thus to provide a negative electrode for lead storage batteries of the type mentioned at the beginning, in which the conductivity is optimized.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Streckrichtung des Streckmetalls parallel zu derjenigen Seite der rechteckigen Platte verläuft, an der die Anschlußfahne angeordnet ist und daß an der betreffenden Seite eine sich über die gesamte Länge erstreckende Bleileiste stromleitend befestigt ist, mit der die Anschlußfahne ein Stück bildetTo solve this problem, the invention provides that the stretching direction of the expanded metal is parallel to that side of the rectangular plate runs on which the terminal lug is arranged and that on the relevant side a lead strip extending over the entire length is attached to conduct electricity, with the the terminal lug forms one piece

Aufgrund dieser Ausbildung wird nicht nur eineBecause of this training there won't be just one

ίο Stromlaufrichtung erzielt sondern es liegt auch eine gleichmäßige Verteilung des Stromes über die Breite der rechteckigen Platte vor.ίο direction of flow achieved but there is also one uniform distribution of the current across the width of the rectangular plate.

Um die Bildung von kontaktmindernden Hohlräumen zwischen der negativen Masse und dem Stützgitter während des Betriebes wirksam zu vermeiden, ist nach einer bevorzugten Ausführungsform das Kupferstreckmetall mit einer Bleischicht überzogen. Dadurch wird die Gefahr herabgesetzt, daß es aufgrund der ständigen Lade- und Entladezyklen in der negativen Masse zu Ablösungserscheinungen am Gitter kommt.About the formation of contact-reducing cavities between the negative mass and the support grid According to a preferred embodiment, the expanded copper metal can be effectively avoided during operation covered with a layer of lead. This will reduce the risk of it being permanent Charging and discharging cycles in the negative mass lead to separation phenomena on the grid.

Zur Verbesserung der Haftung der Bleischicht an dem Kupferstreckmetall ist es zweckmäßig, daß zwischen Bleischicht und Kupfer eine Zinnschicht vorgesehen ist. Während die Zinnschicht durch eine Feuerveizinnung aufgebracht werden soll, erfolgt die anschließende Verbleiung zweckmäßig auf galvanischem Wege.To improve the adhesion of the lead layer to the expanded copper metal, it is useful that between Lead layer and copper a tin layer is provided. While the tin layer by a fire tin plating is to be applied, the subsequent lead is expediently carried out by galvanic means.

Die Erfindung wird im folgenden beispielsweise anhand der Zeichnung beschrieben, weiche eine Draufsicht einer erfindungsgemäßen negativen Elektrode zeigt.The invention is described below, for example, with reference to the drawing, which shows a Figure 10 shows a plan view of a negative electrode according to the invention.

Nach der Zeichnung besteht eine Gitterplatte ausAccording to the drawing, a grid plate consists of

einem zunächst feuerverzinnten und dann verbleiten Kupferstreckmetall 11, dessen Streckrichtung in der Zeichnung durch zwei entgegengesetzt weisende Pfeile veranschaulicht ist.an initially hot-dip tinned and then leaded expanded copper metal 11, the direction of stretching in the Drawing is illustrated by two oppositely pointing arrows.

An den parallel zur Streckrichtung verlaufenden Seite der Streckmetallplatte 11 sind vorzugsweise aus Blei bestehende Leisten 13, 14 befestigt, welche zum einen den Zweck haben, einen mechanisch festen Abschluß für die Platte zu bilden, während die Leiste 13 außerdem zur Stromzu- bzw. -abführung dient. Die Leiste 13 besteht aus einem Stück mit der Bleifahne 12, an die Stromzu- bzw. -abführungsanschlüsse angelegt werden.On the side of the expanded metal plate 11 running parallel to the stretching direction, they are preferably made of lead existing strips 13, 14 attached, which on the one hand have the purpose of a mechanically solid closure for to form the plate, while the bar 13 also serves to supply or discharge current. The bar 13 consists made of one piece with the lead flag 12, to which the power supply and discharge connections are applied.
