Description

Verfahren zum Formieren von Bleisammlerplatten. Nach der Erfindung erfolgt die Formierung von Bleisammlerplatten in der Weise, daß sie in Säure entladen werden, bis ihre wirksame Masse vollständig oder zum allergrößten Teil in Bleisulfat unter entsprechender Bindung der Schwefelsäure umgewandelt ist, worauf sie wieder geladen werden. Durch diese Behandlung erhalten die Platten söfort eine sehr große Kapazität, selbst wenn sie nach der tiefen Entladung mit einer Trockenfüllung, z. 'B. gallertartiger oder trockener Kieselsäure, versehen werden. Ferner ist es hierdurch möglich, die mit tiefentladenen Platten versehenen Elemente ohne jede Füllung oder mit einer säurefreien bzw. säurearmen Trokkenfüllung zu versenden, ohne für Beschaffung geeigneter Säure am Bestimmungsort sorgen zu müssen, da sie dort nur mit destilliertem Wasser nachzufüllen sind, welches sich bei der Ladung in Säurenormaler Dichte verwandelt. Die obige Tiefentladung gelingt durch Anwendung sehr geringer Entladestromdichten gegen Ende der Entladung, während die übrige Entladung mit höheren Stromdichten vorgenommen wird. Beispielsweise wird der Sammler auf einen konstanten S'%'iderstand entladen, der so bemessen ist, daß der Sammler anfänglich den dreistündigen Entladestrom liefert. Da sich der Entladestrom nach dem Spannungsabfall des Sammlers sehr stark verringert, braucht eine solche Entladung etwa io bis I¢ Tage. Damit die. aus destilliertem Wasser bestehende Füllung von Anfang an eine gewisse Leitfähigkeit erhält, kann man in die Elemente vorgängig eine kleinQ Menge unschädlichen, gutleitenden Salzes, z. B. Natriumsulfat, in fester Form einfüllen.Process for forming lead collector plates. According to the invention lead collector plates are formed in such a way that they discharge in acid until their effective mass is completely or for the most part in lead sulphate under appropriate binding the sulfuric acid is converted, whereupon it again Loading. This treatment immediately gives the panels a very large one Capacity, even if it is filled with a dry fill, e.g. 'B. gelatinous or dry silica. Furthermore, it is through this possible, the elements provided with deeply discharged plates without any filling or to be sent with an acid-free or low-acid dry filling, without for procurement Appropriate acid must be provided at the destination, as it is only there with distilled Top up with water, which turns into normal acid density during charging. The above deep discharge is achieved by using very low discharge current densities towards the end of the discharge, while the rest of the discharge has higher current densities is made. For example, the collector is set to a constant S '%' resistance discharged, which is dimensioned so that the collector initially the three-hour discharge supplies. Because the discharge current is very strong after the voltage drop of the collector is reduced, such a discharge takes about 10 to 1 ¢ days. So that. from distilled Water can have a certain conductivity right from the start a small amount of harmless, highly conductive salt is previously added to the elements, z. B. sodium sulfate, fill in solid form.
