Description

Positive Luftsauerstoffelektrode Die vorliegende Erfindung bezieht sich auf eine positive Luftsauerstoffelektrode mit einem Zusatz von festem Salmiak von mindestens 30 g je roo ccm der fertigen sauerstoffübertragenden positiven Elektrode ohne Ableiter für galvanische Elemente mit einer negativen Zinkelektrode und bzw. oder einem zink- oder mangansalzhaltigen Elektrolyten. Während bei den positiven Elektroden mit chemisch wirkenden Depolaxisatoren, insbesondere Manganoxyden, sich heraüsgestellt hat, daß der Gehalt an festem Salmiak eine bestimmte Grenze nicht überschreiten darf, um nicht eine Verringerung der Depolarisationskraft oder einen verhältnismäßig starken Zinkangriff befürchten zu müssen, beruht die vorliegende Erfindung auf der Erkenntnis, daß bei Luftsauerstoffelektroden ein vierhältnismäßig hoher Gehalt an Salmiakaußerordentlich günstige Wirkungen hat.Positive atmospheric oxygen electrode The present invention relates to a positive atmospheric oxygen electrode with an addition of solid ammonia of at least 30 g per roo ccm of the finished oxygen-transmitting positive electrode without an arrester for galvanic elements with a negative zinc electrode and / or an electrolyte containing zinc or manganese salts. While in the case of the positive electrodes with chemically acting depolarization agents, in particular manganese oxides, it has been found that the content of solid ammonia must not exceed a certain limit in order not to have to fear a reduction in the depolarization force or a relatively strong zinc attack, the present invention is based on the knowledge that in atmospheric oxygen electrodes a relatively high content of salmiac has extremely beneficial effects.

Es hat sich die überraschende Tatsache ergeben, daß die Luftsauerstoffelektrode auch bei einem so hohen Salmiakzusatz, wie er vorstehend angegeben ist, keinerlei Einbuße in ihrer depolarisierenden Wirkung erleidet. Diese Tatsache ist damit zu erklären, daß der Depolarisator in diesem Falle die die Elektrode durchdringende Luft ist. Hierbei ist die Menge des zugesetzten Salmiaks so zu bemessen, daß die Ausfällung von Salzen des Zinks bzw. Mangans auf oder innerhalb der Elektrode vermieden wird. Demnach wird bei der Zusammensetzung der Elektrode nach der Erfindung von der Tatsache Gebrauch gemacht, daß die Ausfällung der erwähnten Salze, insbesondere der Hydroxyde des Zinks bzw. Mangans, durch Ammoniak mit Sicherheit nicht eintritt, wenn Salmiak im überschuß vorhanden ist. Der in der Elektrode nach der Erfindung enthaltene Salmiak wird nämlich nach Maßgabe der Höhe des Entladestrames und der Entladungsdauer durch das an oder in der Elektrode entstehende Wasser aufgelöst. Der so gelöste Salmiak verhindert mit Sicherheit die Ausfällung der obenerwähnten Salze. Auf diese Weise wird jegliche Inaktivierung, insbesondere jegliche Verkrustung, der Elektrode nach der Erfindung sowohl an der Oberfläche wie auch im Innern verhindert.The surprising fact has emerged that the atmospheric oxygen electrode even with such a high addition of ammonia as indicated above, none at all Suffers loss of their depolarizing effect. This fact is with it too explain that in this case the depolarizer is the one penetrating the electrode Air is. Here, the amount of salmiac added is to be measured so that the Precipitation of salts of zinc or manganese on or within the electrode is avoided will. Accordingly, in the composition of the electrode according to the invention from made use of the fact that the precipitation of the salts mentioned, in particular the hydroxides of zinc or manganese, due to ammonia, will definitely not enter, if there is excess ammonia. That in the electrode according to the invention Salmiak contained is namely according to the amount of the discharge current and the Discharge duration dissolved by the water created on or in the electrode. The ammonia dissolved in this way certainly prevents the above-mentioned precipitation Salts. In this way, any inactivation, especially any incrustation, the electrode according to the invention prevented both on the surface and inside.

Weiterhin haben praktische Versuche ergeben, daß der Salmiak ganz oder teilweise durch organische Ammoniakderivate, beispielsweise durch Mänomethylaminchlorhydrat, ersetzt werden kann. Auch die organischen Ammoniakderivate zeigen die oben beschriebene günstige, eine porenverstopfende Ausfällung von Salzen verhindernde Wirkung, wenn sie in den oben angegebenen Mengen benutzt werden.Furthermore, practical tests have shown that the salmiak completely or partly by organic ammonia derivatives, for example by maenomethylamine chlorohydrate, can be replaced. The organic ammonia derivatives also show those described above favorable effect preventing pore-clogging precipitation of salts, if they are used in the quantities given above.
