Description

Verfahren zur Herstellung von Bleiakkumulatoren mit festgelegtem bzw. verdicktem Elektrolyten Zusatz zum Patent: 1166 305 Im Patent 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.Process for the production of lead-acid batteries with a specified or thickened electrolyte additive to patent: 1166 305 In patent 1166 305 is a lead accumulator has been described with fixed or thickened electrolyte, which is characterized is that the electrolyte contains pectin as a thickener. In addition, the main patent concerns a method for producing these lead-acid batteries, which is characterized is that the addition of pectin to the electrolyte is chosen so that initially one Pectin sol is produced which, after being filled into the accumulator, becomes one in situ Gel solidifies.

Nach der vorliegenden Erfindung lassen sich die Akkumulatoren gemäß dem Hauptpatent vorteilhafterweise nach folgendem Verfahren herstellen: Zunächst werden Folien aus einem elektrolytbeständigen porösen Material mit wäßrigem Pektinsol getränkt. Dem Pektinsol kann ein Füllstoff, wie z. B. großoberflächiges Siliciumdioxid, beigemischt sein. Diese Folien werden getrocknet und dann an Stelle herkömmlicher Scheider zwischen den Elektrodenplatten des Akkumulators angeordnet.According to the present invention, the accumulators according to produce the main patent advantageously according to the following process: First foils made of an electrolyte-resistant porous material with aqueous pectin sol are used soaked. The pectin sol can contain a filler such as. B. large surface area silica, be mixed in. These films are dried and then replaced in place of conventional ones Separator arranged between the electrode plates of the accumulator.

Anschließend werden die vollständigen Plattensätze in die Akkumulatorenbehälter eingesetzt, die entweder bereits mit Akkumulatorensäure gefüllt sind oder danach gefüllt werden. Dort bildet sich aus dem Trockenpektin ein Pektin-Schwefelsäure-Gel, das im Akkumulator als Elektrolyt wirkt. Überschüssige Schwefelsäure kann dann abgegossen werden.The complete sets of plates are then placed in the accumulator container used, which are either already filled with accumulator acid or afterwards be filled. There a pectin-sulfuric acid gel is formed from the dry pectin, which acts as an electrolyte in the accumulator. Excess sulfuric acid can then be poured off will.

Das Verfahren gemäß der vorliegenden Erfindung zeichnet sich durch seine besondere einfache und saubere Handhabung aus.The method according to the present invention is characterized by its particularly simple and clean handling.
