Description

Verfahren zur Erhaltung der Kapazität elektrischer Sammler Bei elektrischen Sammlern, insbesondere Bleisammlern, ergibt sich aus wirtschaftlichen Gründen häufig die Notwendigkeit, solche Sammler nach der Formierung der Elektroden ohne Elektrolyt zu versenden bzw. längere Zeit zu lagern. Man hat daher, um die Elektroden gegen die schädlichen Einwirkungen der Luft zu schützen, die Gefäße solcher Sammler nach Ausgießen des Elektrolyten nach Möglichkeit luftdicht verschlossen. Hierbei ergab sich aber der Nachteil, daß in den so verschlossenen Zellen häufig noch sehr viel Gas entwickelt wurde, wodurch die Gefäße zersprengt wurden oder sonstige Beschädigungen erlitten. Bei mangelndem Luftabschluß ergab sich der weitere Nachteil, däß sich der Zustand der negativen Masse veränderte und bei der Inbetriebsetzung ein Teil dieser Massen nicht wieder reduziert werden konnte. Außerdem zeigten die negativen Platten eine erhebliche Selbstentladung, so daß. der Gebrauchswert der Batterie stark herabgemindert wurde.Procedure for maintaining the capacity of electrical collectors In the case of electrical Collectors, especially lead collectors, often arises for economic reasons the need for such collectors after forming the electrodes without electrolyte to be sent or to be stored for a longer period of time. One therefore has to oppose the electrodes to protect the harmful effects of the air, the vessels of such collectors after Pour out the electrolyte, hermetically sealed if possible. This resulted but there is the disadvantage that there is often still a great deal left in the closed cells Gas was evolved, causing the vessels to burst or other damage suffered. If there was insufficient air exclusion, there was the further disadvantage that it resulted the state of the negative ground changed and a part during commissioning these masses could not be reduced again. Also showed the negative Plates have a significant self-discharge, so that. the utility value of the battery has been greatly reduced.

Bei dem Verfahren gemäß der vorliegenden Erfindung zur Erhaltung der Kapazität elektrischer Sammler, insbesondere von Bleisammlern, welche nach der Formierung der Elektroden ohne Elektrolyt versandt bzw. längere Zeit gelagert und bei welchen die Elektroden im Elementgefäß formiert und nach Ausgießen des Formationselektrolyten aus dem Gefäß auch die erstlichen, den Elektroden und den Scheidern anhaftenden Ionen des Formationselektrolyten beseitigt werden, worauf das Elementgefäß im wesentlichen luftdicht verschlossen wird, werden diese Nachteile dadurch vermieden, daß unter Aufrechterhaltung eines gewissen Wassergehaltes in den Elektroden und den Scheidern die Ionen des Formationselektrolyten durch Entladung einer im Verhältnis zur Kapazität des Sammlers geringen Strommenge elektrisch neutralisiert werden. Diese Neutralisation der Ionen des Formationselektrolyten kann weiterhin durch Einführen von chemisch wirkenden Stoffen unterstützt werden. Erfindungsgemäß können auch die Elementgefäße nach Ausgießen des Formationselektrolyten und nach Beseitigung der restlichen Ionen mit einem indifferenten Gas gefüllt werden.In the method according to the present invention for maintaining the Capacity of electrical collectors, especially lead collectors, which after formation of electrodes shipped without electrolyte or stored for a long time and with which the electrodes are formed in the element vessel and after the formation electrolyte has been poured out from the vessel also the first ones adhering to the electrodes and the separators Ions of the formation electrolyte are eliminated, whereupon the element vessel essentially Is hermetically sealed, these disadvantages are avoided in that under Maintaining a certain water content in the electrodes and the separators the ions of the formation electrolyte by discharging one in proportion to the capacity of the collector can be electrically neutralized. This neutralization the ions of the formation electrolyte can be further introduced by chemical active substances are supported. According to the invention, the element vessels after pouring out the formation electrolyte and after removing the remaining ions be filled with an inert gas.

Wie Versuche gezeigt haben, werden durch dieses Verfahren die obenerwähnten Nachteile sämtlich vermieden, und es zeichnen sich die so behandelten Sammler durch besonders hohe Kapazität aus.As tests have shown, the above-mentioned Disadvantages are all avoided, and the collectors treated in this way stand out particularly high capacity.
