durchsetzter wirksamer Masse.interspersed effective mass.
Bekanntlich haben die nach dem Planteverfahren hergestellten, aus Blei bestehenden ■ Platten für elektrische Sammler, wenn sie als negative Polelektroden verwandt werden, den Nachteil, daß sich in kurzer Zeit ihre Kapazität vermindert, indem die auf ihnen befindliche wirksame Schicht durch Sinterung ihre Porosität verliert. Der bei sogenannten Masseplatten übliche Weg, dies durch ZusatzIt is known that those made of lead and manufactured according to the plant method have ■ Plates for electrical collectors, if they are used as negative pole electrodes Disadvantage that their capacity is reduced in a short time by the on them effective layer loses its porosity due to sintering. The so-called Ground plates usual way of doing this by adding
ίο irgendeines feinpulvrigen inerten Materials zur wirksamen Masse zu verhindern, läßt sich naturgemäß bei den Planteplatten nicht anwenden. Der anderweitig gemachte Vorschlag, die fertigen Planteplatten durch Tauchen in eine entsprechende Lösung und darauffolgende chemische Veränderung des aufgesogenen löslichen Körpers mit inertem Material zu versehen, hat den Nachteil, daß zur Fertigstellung dieser Platten eine größere Reihe von Manipulationen vorgenommen werden muß, wodurch naturgemäß der Herstellungspreis sich erhöht.ίο any fine powdery inert material for To prevent effective mass, of course, cannot be used with the planter plates. The suggestion made elsewhere, the finished plant plates by dipping in a corresponding solution and subsequent chemical modification of the absorbed soluble body to be provided with inert material, has the disadvantage that a large number of manipulations are made to complete these panels must, which naturally increases the manufacturing price.
Das vorliegende Verfahren bietet aber auch sonst noch wesentliche Vorteile vor dem bekannten. Nach letzterem muß die fertig formierte Platte in eine Lösung eines Bariumsalzes oder Bariumhydrat getaucht werden. Von genügend löslichen Bariumsalzen ist nur das Nitrat, Acetat oder das Salz anderer organischer Säuren bekannt. Durch Eintauchen" in den Gebrauchselektrolyten gelangen die Anionen dieser Säuren in letzteren, und es ist jedem Fachmann bekannt, daß Salpetersäure, Essigsäure oder andere organische Stoffe für den Sammler schädlich sind. Will man eine Verunreinigung des Gebrauchselektrolyten vermeiden, so ist es nötig, die Platte nach dem Fällen des Bariumsulfates äußerst sorgfältig auszulaugen, was naturgemäß den Herstellungsprozeß umständlicher und teurer macht. Auch die Benutzung von Bariumhydrat ist nicht vorteilhaft. In .der Kälte ist Bariumhydrat schwer löslich, so daß durch Eintauchen der Planteplatte in die kalte Lösung nicht genug Bariumsulfat der Platte einverleibt werden kann; in heißer Bariumhydratlösung dagegen ist Bleioxyd sehr stark löslich, so daß die erzeugte poröse Schicht teilweise wieder gelöst wird. Allem dem gegenüber bietet das neue Verfahren den Vorteil, daß keinerlei fremde Säuren in den Elektrolyten gelangen und eine besondere Auslaugung der Platte fortfällt, und die einmal erzeugte Formationsschicht nicht vermindert wird- .However, the present method also offers significant advantages over the known one in other ways. According to the latter, the fully formed plate must be immersed in a solution of a barium salt or barium hydrate. Of the barium salts that are sufficiently soluble, only nitrate, acetate, or the salt of others known organic acids. Get into the electrolyte by immersion " the anions of these acids in the latter, and it is known to every person skilled in the art that nitric acid, Acetic acid or other organic substances are harmful to the collector. If you want to contaminate the electrolyte used It is necessary to avoid the plate after the barium sulphate has been precipitated carefully leach out what naturally makes the manufacturing process more cumbersome and expensive power. The use of barium hydrate is also not beneficial. In the cold barium hydrate is sparingly soluble, so that by immersing the plant plate in the cold solution cannot incorporate enough barium sulfate into the plate; in hot Barium hydrate solution, however, lead oxide is very soluble, so that the produced porous Layer is partially dissolved again. In contrast to all of this, the new process offers the Advantage that no foreign acids get into the electrolyte and a special leaching of the plate is omitted, even once The formation layer produced is not reduced.
Vorliegende Erfindung besteht darin, daß dem Blei vor Anfertigung der entsprechend geformten Elektroden andere. Metalle, in geringer Menge beigemischt werden, deren Jgil_--„ fate in Schwefelsäure schwer löslich sind. Als solche kommen die Erdalkalimetalle, in erster LinieüBarium, in zweiter Strontium und Calcium in Frage. Das Barium usw. wird entweder dem Blei in reinem Zustande oder als hochprozentige Bariumbleilegierung zugefügt.The present invention is that the lead before making the accordingly shaped electrodes others. Metals, in low Amount to be added whose Jgil _-- " fate are sparingly soluble in sulfuric acid. As such, the alkaline earth metals come first Line via barium, secondly strontium and calcium in question. The barium etc will either added to lead in its pure state or as a high-percentage barium lead alloy.
Die aus diesem Material hergestellten Elektroden werden in der üblichen Weise, z. B. nach dem Verfahren des D. R. P, 90446 mitThe electrodes made from this material are used in the usual manner, e.g. B. according to the method of D. R. P, 90446 with
einer Planteschicht überzogen. Diese besteht nach Beendigung der Formation im wesentlichen~aus_JBleisuperoxyd, welchem etwas Bleisulfat und eine entsprechende Menge von Bariumsulfat beigemischt ist. Durch elektrolytische Reduktion dieser Platten werden dann negative Polelektroden erhalten, in welchen sich das vorgängig erzeugte Bariumsulfat unverändert befindet. Derartige Elektroden halten eine große Zahl von Ladungen und Entladungen aus, ohne ihre ursprüngliche Kapazität wesentlich zu verändern.covered with a tarpaulin layer. After the formation is complete, this consists essentially of lead superoxide, which is mixed with a little lead sulphate and a corresponding amount of barium sulphate. By electrolytic Reduction of these plates are then obtained in which negative pole electrodes the previously produced barium sulfate is unchanged. Hold such electrodes a large number of charges and discharges without losing their original capacity to change significantly.
An Stelle des reinen Bleies, welchem das Erdalkalimetall zugefügt wird, kann auch eine Legierung von Blei und Alkalimetall verwendet werden, wodurch sich in bekannter Weise der Formationsprozeß einfacher und rascher durchführen läßt. Es läßt sich diese Methode mit Vorteil anwenden, indem man z. B. eine Bleinatriumlegierung mit einer zur vollständigen Umsetzung des Natriums ungenügenden Menge von Chlorbarium erhitzt und so eine Bleinatriumbariumlegierung erhält, welcher man erforderlichenfalls noch reines Blei zufügt. Instead of the pure lead to which the alkaline earth metal is added, a Alloy of lead and alkali metal are used, making them in a known manner the formation process can be carried out more easily and quickly. It can be this method use with advantage by z. B. a lead sodium alloy with a complete Reaction of the sodium insufficient amount of chlorobarium is heated and thus a lead sodium barium alloy is obtained, which if necessary, pure lead is also added.
Endlich kann man eine der erwähnten erdalkalihaltigen Bleilegierungen in einer entsprechend dünnen Schicht auf die aus reinem Blei, Hartblei oder einem anderen geeigneten Material bestehenden Träger der Polelektroden durch Gießen, Walzen o. dgl. aufbringen, oder Vertiefungen der Träger, wie Rillen oder Gitteröffnungen, mit ihr füllen.Finally you can get one of the alkaline earth lead alloys mentioned in a corresponding thin layer on the one made of pure lead, hard lead or any other suitable Material existing carrier of the pole electrodes by casting, rolling or the like. Apply, or Fill recesses in the carrier, such as grooves or grid openings, with it.
