Description
Verfahren zur Herstellung von Elektrodenplatten für Bleiakkumulatoren. Die Erfindung betrifft ein Verfahren zur Herstellung von Elektrodenplatten, so genannte Sammlerplatten, für Bleiakkumula toren, und zwar wird der Erfindung gemäss auf elektrolytischem Wege eine Bleilegie rung hergestellt, aus der alsdann die Elek- trodenplatten geformt werden.
Als Ausführungsbeispiel wird die Her stellung von Elektrodenplatten aus einer Bleialkali- oder Bleierdalkalimetallegierung beschrieben.
Bei der Herstellung von Bleialkali- oder Bleierdalkalimetallegierungen für Sammler platten ist man bisher so vorgegangen, dass man in das geschmolzene Blei das freie Alkali- oder Erdalkalimetall eingetragen hat. Diese Art der Herstellung hat den grossen Nachteil, dass ein grosser Teil dieses Me- falles unter Feuererscheinung verbrennt und verloren geht, sobald man das Alkali- oder Erdalkalimetall in das besehmolzene Blei einbringt.
Man ist daher nicht in der Lage, auf .diesem Wege eine gewünschte Legierung mit bestimmtem Gehalt gleichmässig herzu stellen, weil je nach Geschicklichkeit mehr oder weniger Metall bei der Legierung ver brennt. Auch Temperaturunterschiede und andere Abweichungen können den Metall verlust und das Ergebnis beeinflussen.
Stellt man dann aus verschiedenen An sätzen,der Legierung Sammlerplatten her, so ergeben sich auch verschiedene Werte hin sichtlich der Kapazität und Lebensdauer .des Akkumulators. Man kann somit nicht mit feststehenden Werten rechnen. Die Erfin dung will einen neuen Weg zeigen, um,die sen Mangel zu beseitigen.
Bei der Herstellung der Akkumulatoren platten aus einer Legierung von Blei mit einem A1ka.Ii- oder Erdalkalimetall kann für die elektrolytische Herstellung der Bleilegie rung als Kathode geschmolzenes Blei und als Elektrolyt Xtznatron, Pottasche oder ein an deres Alkali- bezw. Erdalkalihydrogyd oder -karbonat, gegebenenfalls ein Salz dieser Me talle, verwendet werden. Ausserdem können noch leicht niederschmelzbare Verbindungen verwendet werden. Als Anode kann Eisen, Nickel oder irgend ein anderes geeignetes Material, zum Beispiel auch Kohle, benutzt werden.
Je nach der angewendeten Stromstärke und Zeitdauer hat man es in der Hand, Le- gierungen mit beliebigem Prozentgehalt an den erwähnten Alkali- bezw. Erdalkali- metallen herzustellen. Bei diesem Verfahren wird das gesamte freiwerdende Alkali- bezw. Erda-lkalimetall im Augenblick des Ent stehens von dem geschmolzenen Blei gelöst, so .dass keinerlei Verluste entstehen können.
Bei Durchführung des Verfahrens kann man zum Beispiel in folgender Weise ver fahren: Man lässt in einem Kessel 20 kg Blei einschmelzen und scheidet aus darauf befind lichem Ätznatron soviel Alkalimetall ab, dass man eine Legierung von 18 % Natriumgehalt erhält. Es scheidet sich dabei pro AmpAre- stunde beispielsweise 0,65 gr freies Natrium ab, das von .dem geschmolzenen Blei auf genommen wird.
Natürlich kann man die Zahlenwerte und prozentualen Verhältnisse je nach der ge wünschten Legierung ganz verschieden wäh len.
Process for the production of electrode plates for lead accumulators. The invention relates to a method for the production of electrode plates, so-called collector plates, for lead accumulators, namely according to the invention a lead alloy is produced electrolytically from which the electrode plates are then formed.
As an exemplary embodiment, the manufacture of electrode plates from a lead alkali or lead alkaline earth metal alloy is described.
In the production of lead alkali or lead alkaline earth metal alloys for collector plates, the procedure so far has been to introduce the free alkali or alkaline earth metal into the molten lead. This type of production has the major disadvantage that a large part of this metal burns under the appearance of a fire and is lost as soon as the alkali or alkaline earth metal is introduced into the molten lead.
One is therefore not able to produce a desired alloy with a certain content evenly in this way, because more or less metal burns in the alloy depending on skill. Temperature differences and other deviations can also affect the metal loss and the result.
If one then uses different approaches to produce the alloy collector plates, different values also result with regard to the capacity and service life of the accumulator. So you cannot count on fixed values. The invention wants to show a new way to eliminate this deficiency.
In the manufacture of the accumulator plates made of an alloy of lead with an A1ka.Ii- or alkaline earth metal, for the electrolytic production of the lead alloy, molten lead can be used as the cathode and xtznatron, potash or another alkali or other alkali metal as the electrolyte. Alkaline earth hydroxide or carbonate, optionally a salt of these metals, can be used. In addition, easily meltable compounds can be used. Iron, nickel or any other suitable material, for example also carbon, can be used as the anode.
Depending on the current strength used and the duration of time, you have the option to choose alloys with any percentage of the alkali or alkali metals mentioned. To produce alkaline earth metals. In this process, the entire alkali or alkali released. Erdalkalimetall detached from the molten lead at the moment of formation, so that no losses can occur.
When carrying out the process, one can, for example, proceed in the following way: 20 kg of lead are melted down in a kettle and enough alkali metal is deposited from the caustic soda on it that an alloy with 18% sodium content is obtained. For example, 0.65 gram of free sodium is deposited per ampere hour, which is absorbed by the molten lead.
Of course, the numerical values and percentage ratios can be chosen quite differently depending on the desired alloy.
