Description

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.The so-called reboiling of the electrical lead collector stirs in most cases from contamination of the electrolyte by compounds of antimony which, when charged, deposited metallic antimony on the negative pole electrodes becomes and there, be it through the formation of local elements, be it through reduction the hydrogen overvoltage the discharge of this electrode with evolution of hydrogen causes.

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.It has now been found that this evolution of hydrogen always and particularly strong occurs when the negative pole electrodes are opposite positive electrodes, their Frames, flags or other support parts that are flushed with the electrolyte and are not covered by the effective mass, made of hard lead with a considerable content of Consist of antimony. It is in these places that part of their antimony content is used during loading dissolved by the electrolyte, and so there is a strong contamination of the same with antimony compounds.

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 TeileThis disadvantage is with the electrical lead collector with a positive electrode, the parts of which are not covered by the effective mass of a preferably antimony-containing one Lead alloy exist, eliminated according to the invention in that these parts

mit einem aus einer wäßrigen Kautschukdispersion durch Tauchen, Spritzen, Anstreichen o. dgl. aufgebrachten und dort durch Trocknung oder Gerinnung und gegebenenfalls Vulkanisation verfestigten Weich- oder Hart- 35 gummiüberzug versehen sind. Man hat zwar schon die Masseträger von Sämmlerplatten an verschiedenen Stellen durch Aufbringen einer knetbaren Masse mit einer isolierenden Schicht überzogen. Diese Schichten konnten 4" 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 45 wird.with one of an aqueous rubber dispersion by dipping, spraying, painting o. The like. Applied and there by drying or coagulation and optionally Vulcanization solidified soft or hard rubber coating are provided. One has already the mass carriers of Sämmlerplatten in different places by applying a kneadable mass coated with an insulating layer. These layers could be 4 " but should never be applied evenly and densely to the substrate, and likewise it was not possible to cover fine profiles with such a layer as this is achieved in the electrode according to the invention.
