Einrichtung zur Vermeidung des Nachkochens in elektrischen Bleisammlern.
Das sogenannte Nachkochen der elektrischen Bleisammler rührt in den meisten Fällen von einer Verunreinigung des Elektrolyten durch Verbindungen des Antimons her, aus welchem bei der Ladung metallisches Antimon auf die negativen Polelektroden niedergeschlagen wird und dort, sei es durch Bildung von Lokalelementen, sei es durch Verringerung der Wasserstoffüberspannung die Entladung dieser Elektrode unter Wasserstoffentwicklung bewirkt.
Es wurde nun gefunden, dass diese Wasserstoffentwicklung stets und besonders stark eintritt, wenn den negativen Polelektroden positive Elektroden gegenüberstehen, deren Rahmen, Fahnen oder sonstige Trägerteile, welche vom Elektrolyt bespült werden und von der wirksamen Masse nicht bedeckt sind, aus Hartblei mit beträchtlichem Gehalt an Antimon bestehen. An diesen Stellen wird nämlich beim Laden ein Teil ihres Antimongehaltes vom Elektrolyt gelöst und es kommt so eine starke Verunreinigung desselben mit Antimonverbindungen zustande.
Dieser Übelstand wird bei dem elektrischen Bleisammler mit einer positiven Elektrode, deren von der wirksamen Masse nicht bedeckten Teile aus einer vorzugsweise antimonhaltigen Bleilegierung bestehen, nach der Erfindung dadurch beseitigt, dass diese Teile mit einem aus einer wässerigen Kautschukdispersion durch Tauchen, Spritzen, Anstrichen od. dgl. aufgebrachten und dort durch Trocknung oder Gewinnung und gegebenenfalls Vulkanisation verfestigten Weich-oder Hartgummiüberzug versehen sind. Man hat zwar schon die Masseträger von Sammlerplatten an verschiedenen Stellen durch Aufbringen einer knetbaren Masse mit einer isolierenden Schicht überzogen.
Diese Schichten konnten aber niemals gleichmässig und dicht auf die Unterlage aufgebracht werden und ebenso war es nicht möglich, feine Profilierungen mit einer solchen Schicht zu bekleiden, wie dies bei der Elektrode nach der Erfindung erzielt wird.

Device for avoiding reboiling in electrical lead collectors.
The so-called reboiling of the electrical lead collector stems in most cases from a contamination of the electrolyte by compounds of the antimony, from which metallic antimony is deposited on the negative pole electrodes during the charge and there, either through the formation of local elements, or through the reduction of the Hydrogen overvoltage causes the discharge of this electrode with evolution of hydrogen.
It has now been found that this hydrogen development always occurs and particularly strongly when the negative pole electrodes are opposite to positive electrodes, their frames, flags or other support parts, which are flushed by the electrolyte and are not covered by the effective mass, made of hard lead with a considerable content of Consist of antimony. This is because part of its antimony content is dissolved by the electrolyte at these points during charging, and this results in severe contamination of the same with antimony compounds.
This drawback is eliminated in the electrical lead collector with a positive electrode, the parts of which are not covered by the effective mass of a lead alloy preferably containing antimony, according to the invention that these parts with an aqueous rubber dispersion by dipping, spraying, painting or. Like. Applied and provided there by drying or extraction and optionally vulcanization solidified or hard rubber coating. It is true that the mass carriers of collector plates have already been coated with an insulating layer at various points by applying a kneadable mass.
However, these layers could never be applied evenly and densely to the base and it was also not possible to cover fine profiles with such a layer, as is achieved with the electrode according to the invention.
