Description

Bleiakkumulator mit festgelegtem bzw. verdicktem Elektrolyt Zusatz zum Patent: 1166 305 Im Hauptpatent 1166 305 ist ein Bleiakkumulator mit festgelegtem bzw. verdicktem Elektrolyt geschützt, der dadurch gekennzeichnet ist, daß der Elektrolyt als Verdicker Pektin enthält. Außerdem betrifft das Hauptpatent ein Verfahren zur Herstellung dieser Bleiakkumulatoren, welches dadurch gekennzeichnet ist, daß der Zusatz von Pektin zum Elektrolyten so gewählt wird, daß zunächst ein Pektinsol entsteht, welches nach dem Einfüllen in den Akkumulator in situ zu einem Gel erstarrt.Lead accumulator with fixed or thickened electrolyte Addition to patent: 1166 305 In the main patent 1166 305 a lead accumulator with fixed or thickened electrolyte is protected, which is characterized in that the electrolyte contains pectin as a thickener. In addition, the main patent relates to a process for the production of these lead-acid batteries, which is characterized in that the addition of pectin to the electrolyte is chosen so that first a pectin sol is formed, which solidifies to a gel in situ after being poured into the battery.

Da gemäß des Hauptpatentes der Elektrolyt so mit Pektin vermischt wird, daß zunächst ein Sol von geringer Viskosität entsteht und sich erst in einem späteren Zeitpunkt das Gel bildet, läßt sich dies Verfahren mit besonderem Vorteil nur auf Akkumulatoren anwenden, deren Gehäuse vor dem Verschließen bis zu der für den Betrieb erforderlichen Füllhöhe mit dem flüssigen Sol gefüllt werden können. Dies ist beispielsweise bei der Fabrikation von Knopfzellen unter Umständen nicht möglich oder nur schwierig durchführbar.Since, according to the main patent, the electrolyte is mixed with pectin is that initially a sol of low viscosity is formed and only in one This method can be used with particular advantage at a later point in time when the gel forms only apply to accumulators, the housing of which is up to the for the level required for operation can be filled with the liquid sol. This may not be the case in the manufacture of button cells, for example possible or difficult to implement.

Gemäß der vorliegenden Erfindung wird daher ein Elektrolyt verwendet, der in Form von vorgefertigten Scheiben oder Platten, die aus Pektin-Schwefelsäure-Gel bestehen, zwischen die Elektrodenplatten eingelegt ist. Hierdurch ergeben sich erhebliche fabrikatorische Vorteile; denn nun können die Elektrodenplatten bereits vor dem Einsetzen in den Akkumulatorenbehälter mit dem Elektrolyten zusammengebaut werden; d. h., bei der Endmontage der Akkumulatoren entfällt jeglicher Umgang mit flüssigem Elektrolyt.According to the present invention, therefore, an electrolyte is used in the form of pre-made slices or plates made from pectin-sulfuric acid gel exist, is inserted between the electrode plates. This results in considerable manufacturing advantages; because now the electrode plates can already before Inserting into the accumulator container to be assembled with the electrolyte; d. In other words, during the final assembly of the accumulators, there is no need for any handling of liquid Electrolyte.

Die vorgefertigten Elektrolytscheiben werden vorzugsweise folgendermaßen hergestellt: Ein Pektin-Schwefelsäure-Sol wird in der gewünschten Dicke von beispielsweise 1 mm auf eine glatte Unterlage, z. B. eine Glasplatte, gestrichen. Dort läßt man das Sol zum Gel erstarren, wobei die Geschwindigkeit der Gelbildung durch die Wahl der angewandten Pektin-Konzentration und der Temperatur beeinflußt werden kann. Nachdem die Gelbildung beendet ist, wird die entstandene Schicht gegebenenfalls so zerschnitten, daß die Abmessungen der einzelnen Stücke in etwa den Elektrodenplatten entsprechen. Diese Scheiben lassen sich einfach und sauber handhaben. Sie werden dann etwa wie Separatoren, und zwar vorzugsweise an Stelle derselben, zwischen die Elektrodenplatten gelegt und mit diesen in den Akkumulatorenbehälter eingebaut. Damit ist der Akkumulator fertiggestellt und, sofern geladene Elektrodenplatten verwendet wurden, betriebsbereit. Die Festigkeit des erfindungsgemäß in Form von Scheiben hergestellten Elektrolyten läßt sich noch dadurch erhöhen, daß man ein Stützgerüst oder -gewebe einbaut. Als Stützmaterial eignen sich alle säurefesten hochporösen Körper und Gewebe. Man kann z. B. ein Glasfaservlies mit obigem Pektinsol füllen und es dann zum Gel erstarren lassen.The prefabricated electrolyte disks are preferably made as follows Manufactured: A pectin-sulfuric acid sol is made in the desired thickness of for example 1 mm on a smooth surface, e.g. B. a glass plate, painted. One leaves there the sol solidify to gel, the speed of gel formation being controlled by the choice the applied pectin concentration and the temperature can be influenced. After the gel formation is complete, the resulting layer is optionally Cut up so that the dimensions of the individual pieces approximate the electrode plates correspond. These discs can be handled easily and cleanly. you will be then roughly like separators, preferably in place of the same, between the Electrode plates placed and installed with these in the accumulator container. This completes the accumulator and, if charged, electrode plates have been used. The strength of the invention in the form of Electrolyte made wafers can be increased by having a Build in support structure or fabric. All acid-resistant materials are suitable as support material highly porous body and tissue. You can z. B. a glass fiber fleece with the above pectin sol fill and then let it solidify into a gel.

Der erfindungsgemäße Scheibenelektrolyt bewährt sich insbesondere beim Bau von gasdichten Bleiakkumulatoren, bei denen es auf eine genaue Dosierung des Elektrolyten ankommt. Im praktischen Betrieb zeigen Akkumulatoren, welche mit dem Scheibenelektrolyt ausgerüstet sind, keinerlei Nachteile gegenüber Akkumulatoren mit flüssigem Elektrolyt. Der elektrische Widerstand ist praktisch gleich demjenigen des flüssigen Elektrolyten.The disk electrolyte according to the invention has proven particularly useful in the construction of gas-tight lead-acid batteries, which require precise dosing of the electrolyte arrives. In practical operation, accumulators show which with the disk electrolyte are equipped, no disadvantages compared to accumulators with liquid electrolyte. The electrical resistance is practically the same as that of the liquid electrolyte.
