Description

Verfahren zur Herstellung von Akkumulatorenplatten Die elektrolytische Zerlegung von Bleilegierungen zu porösen Bleiniassen ist bek-annt. Derartighergestellte Elektroden haben jedochkeinenEingang in. diePraxils gefunden.Process for the production of accumulator plates The electrolytic It is well known that lead alloys are broken down into porous lead compounds. Manufactured in this way However, electrodes have not found entry into the practice.

Wie festgestellt wurde, sind s#e praktisch wenig brauchbar, weil sie ungenügende Kapazität und nur geringe Haltbarkeit besitzen und sie sich schon während des Herauslösens des Begleitmetalls deformieren.As has been established, they are of little practical use because they have insufficient capacity and only a short shelf life and they are already during deform the removal of the accompanying metal.

Es wurde nun gefunden, daß Bleile gierungen, welche beispielsweise in ihrer Plattenfo,rm ein Bleigitter bzw. Bleiskelett enthalten, bei der Elektrolyse nicht nur zu wertvollen Kathoden, sondern auch über die Bildun 'g von po-rösem Blei hinaus zu wert vollen Anoden formiert werden können, wenn dafür gesargt wird, daß während der Elektro lyse keine zu hohe Konzentration z. B. an Natriumsulfat entsteht und stets ein gewissier Überschuß an Säure vorhanden ist. Als sehr #iinstig hat sich zudem !eine Stromstärke von etwa 1,2 Amp. pro Quadratdezimeter Oberflaklie. eine Schwefelsäurekonzentration vom spez. Gew. i,io und die Arbeitsweise bei gewöhnlicher Temperatur erwiesen. Arbeitet man dagegen in starken Konzentrationen und mit #,tarken Stromdichten, so findet ein teilweises Herausbröckeln der aktiven Masse statt, und die Elektroden werden minderwertig und unbrauchbar.It has now been found that Bleile governments, which for example in their Plattenfo, rm contain a lead grids or lead skeleton, in electrolysis not only valuable cathode, but also about the Bildun 'g of po-rösem lead out to value full anodes formed can be if it is cured that no too high concentration z. B. sodium sulfate is formed and there is always a certain excess of acid present. A current of around 1.2 amps per square decimeter of surface area has also proven to be very cheap. a sulfuric acid concentration of the spec. Gew. I, io and the operation at ordinary temperature proved. If, on the other hand, one works in strong concentrations and with strong current densities, the active material will partially crumble out, and the electrodes will be inferior and unusable.
