Description

Verfahren zur Herstellung von negativen und positiven Elektroden für elektrische Bleisammler. Die Erfindung betrifft die Herstellung positiver und negativer Elektroden für elektrische Stromsammler unter Verwendung des sich in den bekannten Bleiakkumulatoren abscheidenden Bleischlamms. Dieser als Abfall gewonnene Bleischlamm ist bisher nicht direkt zur Herstellung von Bleistromsammlern verwendet worden, er wurde vielmehr auf metallurgischem Wege zwecks Gewinnung von Schmelzblei oder Bleioxyden t>erhüttet.Process for the production of negative and positive electrodes for electrical lead collectors. The invention relates to the production of positive and negative Electrodes for electric current collectors using the known art Lead accumulators separating lead sludge. This lead sludge obtained as waste has not yet been used directly for the manufacture of lead current collectors, Rather, it was metallurgically used for the purpose of extracting fusible lead or Lead oxides are found.

Um dem an und für sich formlosen Bleischlamm eine plattenförmige Gestalt gemäß der Erfindung zu geben, wird der Schlamm in Hohlräume mit porösen Wandungen eingefüllt. Die porösen Umhüllungen können aus beliebigen Stoffen, Holz, Holzstoffen, Papier, Pappe, Filz usw. hergestellt werden, sofern diese Stoffe weder direkt noch indirekt auf den chemischen Prozeß, den Elektrolyten oder die Elektroden einwirken. Als Stromzuleitung wird in die zwischen den Hohlräumen eingefüllte Masse eine dünne aus Bleiblech bestehende oder eine andere den chemischen Bleisammlerprozeß nicht nachteilig beeinflussende stromleitende Platte eingebettet.Around the in and for itself shapeless lead sludge a plate-like shape According to the invention, the sludge is placed in cavities with porous walls filled. The porous coverings can be made of any material, wood, wood pulp, Paper, cardboard, felt, etc. are manufactured, provided these substances are neither direct nor have an indirect effect on the chemical process, the electrolyte or the electrodes. A thin compound is used as the power supply line in the compound filled between the cavities made of lead sheet or another one does not use the chemical lead collecting process detrimentally influencing conductive plate embedded.

Unterwirft man nun den Bleischlamm der Elektrolyse in verdünnter Schwefelsäure als Kathode (negative Elektrode), so wird der @ or wiegend aus Bleisuperoxydteilchen bestehende Bleischlamm zu metallischem Blei reduziert. Bei diesem Vorgang schließen sich die reduzierten Bleiteilchen in schwammiger Struktur elektrisch leitend zusammen. Wird nun der so gewonnene Bleischwamm der Elektrolyse in verdünnter Schwefelsäure in umgekehrtem Sinne, also als Anode (positive Elektrode), ausgesetzt, so behalten die Masseteilchen die gewonnene metallische Verbindung und elektrische Leitfähigkeit, obwohl sie durch die Elektrolyse als Anode wiederum zu Bleisuperoxy d oxydiert werden. Die durch die elektrolytische Reduktion des Bleischlammes gewonnene metallische Bleimasse ist daher ohne weiteres als positive und negative aktive Masse in dem bekannten Bleisammlerprozeß verwendbar.The lead sludge is now subjected to electrolysis in dilute sulfuric acid as a cathode (negative electrode), the @or is predominantly made of lead peroxide particles existing lead sludge reduced to metallic lead. Close during this process the reduced lead particles come together in a spongy structure in an electrically conductive manner. The lead sponge obtained in this way is now subjected to electrolysis in dilute sulfuric acid in the opposite sense, i.e. exposed as an anode (positive electrode), so keep it the mass particles the obtained metallic connection and electrical conductivity, although they are in turn oxidized to lead peroxy d by electrolysis as an anode. The metallic obtained by the electrolytic reduction of the lead sludge Lead mass is therefore readily available as positive and negative active mass in the known lead collector process usable.
