Im Hauptpatent 1166 305 ist ein Bleiakkumulator mit festgelegtem bzw. verdicktem Elektrolyt beschrieben worden, 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.The main patent 1166 305 describes a lead-acid battery with a fixed or thickened electrolyte which is characterized in that the electrolyte contains pectin as a thickener. aside from that the main patent relates to a process for the production of these lead-acid batteries, which is characterized by this is that the addition of pectin to the electrolyte is chosen so that initially one Pectin sol is produced, which solidifies into a gel in situ after being filled into the accumulator.

Nach der vorliegenden Erfindung lassen sich die Akkumulatoren gemäß dem Hauptpatent besonders vorteilhaft nach folgendem Verfahren herstellen:According to the present invention, the accumulators according to the main patent can be particularly advantageously manufacture according to the following process:

Die mit den Separatoren zu einem vollständigen Plattensatz vereinigten Elektrodenplatten werden mit einer Schwefelsäure getränkt, deren Dichte vorzugsweise um einige Prozent höher ist als die Dichte normaler Akkumulatorensäure. Nach dem Abtropfen der überschüssigen Säure wird der gesamte Plattensatz vollständig in ein wäßriges Pektinsol getaucht.The electrode plates combined with the separators to form a complete set of plates are used with soaked in sulfuric acid, the density of which is preferably a few percent higher than the density more normal Accumulator acid. After the excess acid has drained off, the entire plate set is removed completely immersed in an aqueous pectin sol.

Die in den Poren der Elektrodenplatten und der Separatoren befindliche Schwefelsäure diffundiert dann in das Sol und bildet mit diesem sofort ein Gel, welches die Zwischenräume des Plattensatzes restlos ausfüllt. Das Gelieren nimmt nur wenige Sekunden in Anspruch, so daß der Plattensatz unmittelbar danach aus dem Pektinsolbad genommen und in einem Akkumulatorenbehälter, vorzugsweise in eine Knopfzelle, eingebaut werden kann.The sulfuric acid in the pores of the electrode plates and the separators diffuses then into the sol and immediately forms a gel with it, which completely removes the spaces between the set of plates fills out. Gelation takes only a few seconds, so the set of plates is immediately afterwards taken from the pectin brine bath and in a storage battery container, preferably in a button cell, can be installed.

Da vorzugsweise wäßrige Pektinsole verwendet werden, erfährt die Schwefelsäure, mit welcher der Plattensatz anfangs getränkt wird, beim Gelieren durch das im Pektinsol enthaltene Wasser eine Verdünnung. Es ist daher vorteilhaft, die Konzentration der Schwefelsäure so zu wählen, daß sie nach der Gelbildung den für den betreffenden Akkumulatorentyp richtigen Wert hat.Since preferably aqueous pectin brine is used, the sulfuric acid learns with which the Plate set is initially soaked, while gelling is diluted by the water contained in the pectin sol. It is therefore advantageous to choose the concentration of sulfuric acid so that it is after Gel formation has the correct value for the type of accumulator in question.
