Description

Negativelektrode für elektrische Akkumulatoren. Die Erfindung bezieht sich auf Negativelektroden für elektrische Akkumulatoren, bei denen der Träger für die aktive Masse, z. B. Zink, die bei der Ladung abgesetzt und bei der Entladung aufgelöst wird, aus einem Metall gebildet ist, das bei geschlossenem Stromkreis vom Elektrolyten nicht angegriffen wird. Sie besteht in einer Elektrode dieser Art, in der der Träger aus reinem Silber gefertigt ist.Negative electrode for electrical accumulators. The invention relates on negative electrodes for electrical accumulators, where the carrier for the active mass, e.g. B. zinc, which is deposited during the charge and during the discharge is dissolved, is formed from a metal that is closed when the circuit is not attacked by the electrolyte. It consists of an electrode of this type, in which the carrier is made of pure silver.

Verglichen mit der Verwendung eines versilberten Metalls als Träger für die aktive Masse, bietet die Verwendung einer Silberplatte verschiedene Vorteile, wie z. B. eine Verminderung des Gewichts und der Stärke der Elektrode. Außerdem wird eine Elektrode mit silbernem Träger nicht beschädigt, wenn bei der Entladung die Anschlüsse aus Unachtsamkeit vertauscht werden.Compared to using a silver-plated metal as a carrier for the active mass, the use of a silver plate offers several advantages, such as B. a reduction in the weight and strength of the electrode. aside from that an electrode with a silver backing will not be damaged when discharging the connections are swapped due to carelessness.

Werden bei Elektroden, deren Träger aus einer Metallplatte mit einem Silber- oder anderem Metallüberzug besteht, die Anschlüsse bei der Ladung vertauscht, so kann festgestellt werden, daß sich der Überzug ablöst und das den Kern des Trägers bildende Metall von der Flüssigkeit angegriffen wird, die dadurch verschmutzt wird, wodurch der Akkumulator betriebsunfähig wird.Are for electrodes whose carrier consists of a metal plate with a There is a silver or other metal coating, the connections are mixed up when charging, so it can be determined that the coating is peeling off and that the core of the carrier forming metal is attacked by the liquid, which thereby becomes contaminated, whereby the accumulator becomes inoperative.

Die Elektrode kann beliebig geformt sein und wird am besten aus einer dünnen Platte hergestellt, die gelocht oder gefurcht sein kann.The electrode can be of any shape and is best made of a made of a thin plate that can be perforated or grooved.

Die Elektrode kann ohne Vorbehandlung verwendet werden, indem die aktive Schicht auf dem silbernen Träger bei der Ladung aus dem Elektrolyten, der Zinksalze enthält, niedergeschlagen wird. Jedoch kann die Elektrode auch durch Ablagerung einer Zinkschicht nach irgendeinem bekannten Verfahren vorbereitet werden.The electrode can be used without pretreatment by removing the active layer on the silver carrier when charging from the electrolyte, the Contains zinc salts, is precipitated. However, the electrode can also be deposited by deposition a zinc layer can be prepared by any known method.
