KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, die Bleisuperoxyd enthaltende wirksame Elektrodenmasse auf elektrolytischem Wege in Bleischwamm überzuführen, die Elektroden in Wasser zu spülen und danach zu trocknen, worauf sie beim Aufbau des Sammlers als positive Polelektroden eingestellt werden und der Bleischwamm durch Formation wieder in Bleisuperoxyd übergeführt wird.It is known that the lead peroxide containing effective electrode mass on electrolytic Ways to transfer them to lead sponge, rinse the electrodes in water and then dry them Construction of the collector can be set as positive pole electrodes and the lead sponge is converted back into lead peroxide by formation.
ίο Derartige Bleischwammplatten zeigen aber den Übelstand, daß sie nach längerer Aufbewahrung an Wirksamkeit verlieren, da sie dann nicht mehr durch eine einmalige Ladung, sondern nur durch mehrmaliges Laden auf ihre, volle Kapazität gebracht werden können. Es beruht dies offenbar darauf, daß die Bleischwammteilchen bezw. die aus diesen durch Oxydation an der Luft entstandenen Oxydteilchen zu grobkörniger Masse zusammenwachsen, welche nicht mehr durch einmalige Ladung zu Bleisuperoxyd umgewandelt werden kann.ίο Such lead sponge plates show, however the disadvantage that they lose effectiveness after prolonged storage because they then no longer through a single charge, but only through repeated charging their full capacity can be brought. This is apparently due to the fact that the lead sponge particles respectively the oxide particles formed by oxidation in the air grow together to form a coarse-grained mass, which can no longer be converted to lead peroxide by a single charge.
Nach vorliegender Erfindung wird dieser Übelstand vermieden, wenn man die erzeugte Bleischwammschicht mit der Lösung eines Salzes durchtränkt, welches nach der Verdunstung des Lösungsmittels darin in feiner Verteilung zurückbleibt.According to the present invention, this drawback is avoided if the generated Lead sponge layer soaked with a solution of a salt, which after evaporation of the solvent remains in it in fine distribution.
Zu diesem Zwecke wird die mit Bleischwamm bedeckte Platte zweckmäßig nach Herausnahme aus der verdünnten Schwefelsäure in eine Salzlösung getaucht, eine Zeitlang darin belassen, bis man sicher sein kann, daß die Lösung in alle Poren des Bleischwammes eingedrungen ist, und dann an der Luft getrocknet. Anstatt die Platte nach der Bleischwammerzeugung in verdünnter Schwefelsäure aus dieser herauszunehmen und in die Salzlösung zu tauchen, kann man die Schwammbildung auch unmittelbar in der Salzlösung vornehmen. SFor this purpose, the plate covered with lead sponge is expediently after Removal from the dilute sulfuric acid immersed in a saline solution for a while leave in it until you can be sure that the solution is in all pores of the lead sponge penetrated, and then allowed to air dry. Instead of the plate after the lead sponge production in thinned Taking sulfuric acid out of this and immersing it in the saline solution, one can do the Also create a sponge directly in the saline solution. S.
Als Salzlösung eignen sich Lösungen aller derjenigen Salze, die keine für Sammler schädlichen Stoffe enthalten, und zwar können sie neutral, sauer oder alkalisch reagieren. In erster Linie sind dies schwefelsaure, phosphorsaure, borsaure, kieselsaure usw. Salze. Das Metall des Salzes muß ein solches sein, welches nicht durch das Blei aus der Lösung gefällt wird. Vorzüglich eignet sich hierzu eine Lösung von Zinksulfat.Suitable saline solutions are all those salts that are not suitable for collectors contain harmful substances, which can have a neutral, acidic or alkaline reaction. Primarily these are sulfuric acid, phosphoric acid, boric acid, silicic acid, etc. salts. The metal of the salt must be one which is not precipitated from the solution by the lead. Excellent for this a solution of zinc sulfate.
Die Wirkung eines solchen Salzes erklärt sich dadurch, daß zwischen die einzelnen feinen Körnchen der Bleischwammschicht feste, für die Sammler unschädliche Stoffe eingebettet werden, so daß sie nicht mehr zusammenwachsen können.The effect of such a salt is explained by the fact that between the individual Fine grains of the lead sponge layer embedded in solid substances that are harmless to the collectors so that they can no longer grow together.
. Diese Salze gehen dann oft während des Lagerns chemische Umlagerungen mit dem Bleischwamm ein. So läßt sich z. B. bei Verwendung von Zinksulfat dieses nach einiger Zeit durch Wasser nicht mehr auslaugen, da. These salts then often go along with chemical rearrangements during storage Lead sponge. So z. B. when using zinc sulfate this after some No longer leach time with water, there
sich unter gleichzeitiger Absorption von Luftsauerstoff Bleisulfat und Zinkoxyd gebildet hat. Solche chemische Umsetzungen, bei welchen die einzelnen Bleisulfatfeilchen durch das dazwischen gelagerte Zinkoxyd getrennt bleiben, schaden der Wirkung jedoch in keiner Weise. .lead sulphate and zinc oxide are formed with simultaneous absorption of atmospheric oxygen Has. Such chemical reactions in which the individual lead sulfate particles through the zinc oxide stored in between remains separate, however, does not damage the effect in any way Way. .
Das vorliegende Verfahren unterscheidet sich demnach auch von den bekannten Verfahren jener Art, nach welchen mit Elektrolyt behaftete geladene Platten mit fremden Stoffen äußerlich umkleidet werden, um den Elektrolyten festzuhalten.The present method therefore also differs from the known methods of the kind in which electrolyte-charged plates contain foreign substances externally covered to hold the electrolyte in place.
Nach vorliegendem Verfahren behandelte Bleischwammplatten können mehrere Jahre aufbewahrt werden, ohne an Wirksamkeit zu verlieren, d. h. sie besitzen auch dann noch gleich nach der ersten vollständigen Ladung im positiven Sinne die volle Kapazität.Sponge lead sheets treated according to the present process can last for several years be kept without losing its effectiveness, d. H. they still own Immediately after the first full charge, in a positive sense, the full capacity.
