Description

Verfahren zur Herstellung von Akkumulatorenplatten Zusatz zum Patent 475 242 In dem Patent 475 2¢2 ist ein Verfahren zur Herstellung von Elektroden von Bleiakkumulatoren beschrieben, das darin besteht, daß Platten aus Blei-Bleilegiemungsmetallen in saurer Lösung durch Elektrolyse vom Begleitmetall befreit und zwecks Herstellung positiver Platten gleichzeitig zu Bleisuperoxyd weiter oxydiert werden..Process for the production of accumulator plates Addition to the patent 475 242 In the patent 475 2 [2] a method for the production of electrodes of Lead accumulators described, which consists in plates made of lead-lead alloy metals freed from accompanying metal in acidic solution by electrolysis and for the purpose of manufacture positive plates can be further oxidized to lead peroxide at the same time.

Es wurde nun gefunden, daß die elektrolytische Herauslösung des Bleilegierungsmetalles aus den Bleiplatten und die daran anschließende Formierung mit großem Vorteil auch in Wasser bzw. schwach alkalischer Lösung vorgenommen werden kann. Diese Arbeitsweise besitzt gegenüber der in dem Hauptpatent gekennzeichneten den großen Vorteil, daß beispielsweise bei Verwendung von technisch sehr leicht herstellbaren Blei-Bleinatriumplatten das Na aus den Platten in technisch sehr gut verwendbare Natronlauge übergeführt wird. Das Verfahren. läßt sich am zweckmäßigsten durchführen, wenn möglichst starke Ströme, z. B. 15 bis 25 Amp. und darüber pro Quadratdezimeter, Verwendung-finden. Bei Verwendung von niedrigen Stromstärken, z. B,. 2 biss 3 Amp. pro Quadratdezimeter, findet ein starkes Herausblühen des gebildeten porösen Bleies aus dem Bleigerippe statt, und die so erzeugten poröser Bleiaggregate sind unbrauchbar.It has now been found that the electrolytic dissolution of the lead alloy metal from the lead plates and the subsequent formation can also be carried out with great advantage in water or a weakly alkaline solution. This operation has the great advantage over the designated in the main patent, for example, that with the use of technically very easy to manufacture lead and lead plates atrium is converted Na from the plates in a technically very well usable sodium hydroxide solution. The procedure. can be carried out most appropriately when the strongest possible currents, z. B. 1 5 to 25 Amp. And above per square decimeter, use-find. When using low currents, e.g. B ,. 2 to 3 amps. Per square decimeter, the porous lead formed blooms out of the lead frame, and the porous lead aggregates thus produced are unusable.

Die elektrolytische Zersetzung in der :oben geschilderten Weise führt schon. in kürzester Zeit, beispielsweise in 2 Stunden, zu völlig normalen porösen Bleiaggregaten, deren poröses Blei teilweise in Bleioxyd Übergefülät ist, was dadurch erkenntlich ist, daß sich eine zersetzte Platte nach den Abspülen mit Wasser beim Eintauchen in verdünnter Schwefelsäure sofort mit einem weißen Überzug von Bleisulfat überzieht. Am zweckmäßigsten wird nach dem Herauslösen des Begleitmetalls, z. B. des Natriums, der Elektrolyt entfernt und bei der Weiter'verarbei'tung der Platten zu Anoden durch verdünnte Schwefelsäure ersetzt. Bei der alkalischen Elektrolyse wird mit zunehmender Konzertration der Natronlauge und bei fortschreitendem Entfernung des Begleitmetalls eine geringe Menge Blei oder Bleioxyd 'an der Anode gelöst. Durch die Verwendung mehr oder weniger hoher Konzentrationen des Begleitmetalls können mehr oder weniger hochporöse Elektroden erzeugt werden..The electrolytic decomposition in the manner described above leads beautiful. in a very short time, for example in 2 hours, to completely normal porous Lead aggregates, the porous lead of which is partly overfilled in lead oxide, which is the result it can be seen that a decomposed plate appears after rinsing with water Immersion in dilute sulfuric acid immediately with a white coating of lead sulfate covers. Most expediently after the removal of the accompanying metal, z. B. of the sodium, which removes the electrolyte and during the further processing of the plates to anodes replaced by dilute sulfuric acid. With alkaline electrolysis becomes with increasing concentration the Caustic soda and with progressing Removal of the accompanying metal a small amount of lead or lead oxide on the anode solved. By using more or less high concentrations of the accompanying metal more or less highly porous electrodes can be produced ..
