Description
Flüssigkeitsdichtes und stoßfestes galvanisches Trockenelement, insbesondere für Stabbatterien Bei den bisher verwendeten Ummantelungen galvanischerTrockenelemente, die einen Elektrolytaustritt verhindern und gleichzeitig die Elemente gegen mechanische Verformung schützen, hat man in fast allen Fällen die Ummantelung aus einem inneren Pappschicht- und einem äußeren Metallmantel zusammengesetzt, wobei die Auswahl des Metalls nach rein fertigungstechnischen Gesichtspunkten erfolgte.Liquid-tight and shock-resistant galvanic dry element, in particular for stick batteries With the sheathing used up to now for galvanic dry elements, which prevent electrolyte leakage and at the same time protect the elements against mechanical To protect deformation, in almost all cases the sheathing comes from an interior Cardboard layer and an outer metal jacket, with the choice of the Metal was made according to purely technical manufacturing aspects.
Es kann jedoch selbst bei Verwendung einer Papphülse mit Bitumenzwisahenlage zum Austreten von. Elektrolyt aus dem Becher und anschließenden Durchfeuchten der genannten Pappzwischenlage kommen. In diesem Fall stehen zwei metallische Teile, nämlich der Becher des Elements und der äußere metallische Schutzmantel, mit dem gleichen Elektrolyt in Verbindung. -Es, kommt daher zur Ausbildung eines. Lokalelements und zu. starken Korrosionen, entweder des inneren.oder des äußeren Metallteiles. Auf Grund der vorliegenden Erfindung wird dieser Nachteil dadurch vermieden, däß der äußere Schutzmantel aus einem solchen Metall besteht, das in der elektrochemischen Spannungsreihe an derselben oder einer unmittelbar benachbarten Stelle steht, wie das Metall des inneren Bechers des Elements. Auf diese Weise wird eine Lokalalementbildung und damit das Durchfressen des innerem: oder äußeren Metallgefäßes sicher vermieden. Weiterhin kann, man nun an Stelle der bntumenhaltigen Zwischenlege eine billigere und einfacher herzustellende Pappzwischenlage ohne Bitumen, verwenden. Schließlich wird der innere Lacküberzug des Metallmantels eingespart. Es ergibt sich also aus der zweckentsprechenden Auswahl des Metalls bezüglich seiner Stellung in. der elektrochemischen Spannungsreihe, also eben. durch die Tatsache, daß Mantelmaterial und Bechernater!ia1 keine oder nur eine geiringe elektrochemische Potentialdifferenz gegeneinander aufweisen, sowohl ein erheblicher fabrikatorischer Fortschritt wie auch ein wesentlich besserer Schutz gegen Elektrolytaustritt.However, even when using a cardboard tube with a bitumen seam layer, it can leak. Electrolyte come out of the cup and then soak the above-mentioned cardboard liner. In this case, two metallic parts, namely the cup of the element and the outer metallic protective jacket, are in contact with the same electrolyte. - It comes, therefore, to the training of one. Local element and to. strong corrosion, either of the inner or outer metal part. On the basis of the present invention, this disadvantage is avoided in that the outer protective jacket consists of a metal which is in the electrochemical series at the same or an immediately adjacent point as the metal of the inner cup of the element. In this way a local element formation and thus the erosion of the inner or outer metal vessel is reliably avoided. Furthermore, you can now use a cheaper and easier to manufacture cardboard interlayer without bitumen instead of the bone-containing intermediate layer. Finally, the inner lacquer coating of the metal jacket is saved. It thus results from the appropriate selection of the metal with regard to its position in the electrochemical series, that is to say. Due to the fact that the jacket material and the cup holder generally have no or only a slight electrochemical potential difference from one another, both a considerable manufacturing progress and a much better protection against the escape of electrolyte.
