Description
Aus einem Gemisch von verdünnter Schwefelsäure und Phosphorsäure bestehender Elektrolyt für Bleisammler 2n den Bedienungsvorschriften für Bleisammler wird stets davor gewarnt, den Sammler zu tief zu entladen und im entladenen Zustande längere Zeit stehenzulassen, da hierdurch die sogenannte schädliche Sulfatation eintritt, nämlich die Bildung größerer Kristalle von Bleisulfat, welche das Krümmen und Wachsen der positiven Platten verursachen und sich bei der darauffolgenden Ladung nur langsam und unvollständig in die Ausgangsstoffe zurückführen lassen.Consists of a mixture of dilute sulfuric acid and phosphoric acid Electrolyte for lead collectors 2n the operating instructions for lead collectors is always warned against discharging the collector too deeply and longer when discharged Allow time to stand, as this causes what is known as harmful sulfation to occur, namely the formation of larger crystals of lead sulphate, which cause it to warp and grow of the positive plates and only slowly when the subsequent charge and return them incompletely to the starting materials.
Vorliegende Erfindung beruht auf der Entdeckung, daß die schädliche Sulfatation auch bei sehr langem Stehen des Sammlers in tief entladenem Zustande nicht eintritt, wenn der aus verdünnter Schwefelsäure bestehende Elektrolyt eine geringe Menge Phosphorsäure enthält. Als zweckmäßig hat sich ein Gehalt von io g wasserfreier Orthophosphorsäure im Liter Elektrolyt gezeigt, doch kann dieser Gehalt ohne Nachteile nach oben oder unten verändert werden, soll aber nicht mehr als 2o g betragen, da eine wesentliche Erhöhung die Spannung und Kapazität des Sammlers verringern würde. Die Phosphorsäure kann dein Elektrolyt zugefügt werden-als Orthophosphorsäure oder auch in Form von Meta- oder Pyrophosphorsäure, die im Sammler in Orthophosphorsäure übergehen. Der Zusatz in Form phosphorsaurer Salze zum Elektrolyt ist nicht zu empfehlen, da die Kationen der nur in Frage kornirrenden Salze der Alkalien oder des Ammoniaks die Lebensdauer der Sammlerplatten verkürzen. Es ist daher wesentlich, daß der Elektrolyt frei von Salzen der Alkalien und des Ammoniaks ist. Dagegen ist es angängig, bei Herstellung der Platten als wirksame Masse Bleiphosphat allein oder in Gemisch mit Bleioxyden zu verwenden oder die Bleioxyde mit Phosphorsäure zu einer schmierfähigen und erhärtenden Paste anzumachen, wenn die Platten dauernd in demselben Elektrolyt verbleiben, in welchem sie ihre Formation durchgemacht haben und welcher daher die ursprünglich in der wirksamen Masse vorhandene Phosphorsäure enthält.The present invention is based on the discovery that the harmful Sulphation even if the collector has been standing for a very long time in a deeply discharged state does not occur if the electrolyte consisting of dilute sulfuric acid is a Contains a small amount of phosphoric acid. A content of 10 g has been found to be expedient anhydrous orthophosphoric acid per liter of electrolyte, but this content can be can be changed up or down without disadvantages, but should not be more than 2o g, as a substantial increase in the voltage and capacity of the collector would decrease. The phosphoric acid can be added to the electrolyte - as orthophosphoric acid or in the form of meta- or pyrophosphoric acid, which in the collector is orthophosphoric acid pass over. The addition of phosphoric acid salts to the electrolyte is not recommended, there are the cations of the only grainy salts of alkalis or ammonia shorten the life of the collector plates. It is therefore essential that the electrolyte is free from salts of alkalis and ammonia. On the other hand, it is reasonable to Production of the plates as an effective mass of lead phosphate alone or in admixture with To use lead oxides or the lead oxides with phosphoric acid to a lubricious one and to make hardening paste if the plates are permanently in the same electrolyte remain in which they went through their formation and which therefore the contains phosphoric acid originally present in the effective composition.
Die Bleisammler, welche mit dem Elektrolyt nach der Erfindung versehen sind, bieten gegenüber den- bisherigen den großen praktischen Vorteil, daß sie infolge Wegfalls der schädlichen Sulfatation unempfindlich gegen zu tiefe Entladung und langes Stehenlassen in entladenem Zustande sind, und claß sie daher keine sorgfältige, sachgemäße Wartung benötigen.The lead collector provided with the electrolyte according to the invention are, offer the great practical advantage over the previous that they as a result Elimination of the harmful sulfation, insensitive to too deep discharge and long standing in a discharged state, and therefore do not allow them to be careful, require proper maintenance.
