Description

Elektrisches Primärelement Die Erfindung betrifft ein elektrisches Primärelement, welches aus einer Elektrode aus Magnesium und einer für die Luft zugänglichen Faserstofschicht besteht, «selche in Berührung mit dieser Elektrode zwischen ihr und der zweiten Elektrode liegt und zur Aufnahme des Elektrolyten und zur Herbeiführung der Luftdepolarisation dient. ' Die Erfindung stützt sich auf die Erkenntnis, daß gewisse Elektrolyte von besonders günstigem Einfluß auf die Depolarisationswirkung sind. Als solche Elektrolyte dienen erfindungsgemäß Lösungen von Kaliumjodid oder Kaliumbromid.Electrical primary element The invention relates to an electrical primary element Primary element, which consists of an electrode made of magnesium and one for the air accessible fiber layer consists, «which is in contact with this electrode lies between it and the second electrode and to accommodate the electrolyte and serves to induce air depolarization. 'The invention is based on the knowledge that certain electrolytes have a particularly beneficial influence on the Are depolarization effects. According to the invention, solutions are used as such electrolytes of potassium iodide or potassium bromide.

Eine Zelle gemäß der Erfindung besteht beispielsweise aus einer positiven Elektrode aus Magnesium oder einer magnesiumreichen Legierung (z. B. einer Legierung von 2 bis 7 0'o Aluminium, Rest handelsübliches NI1gnesium, oder einer Legierung aus 7 0'o Aluminium, i bis 2 (o Mangan, Rest Magnesium') und einer negativen Elektrode aus Kupfer, Silber, Platin oder Kohle, wobei diese Elektroden mit Poren oder Durchtrittskanälen für die Luft versehen sein oder gegebenenfalls aus Drahtnetz bestehen können. Zwischen beiden Elektroden befindet sich in Berührung mit diesen eine Faserstoffschicht, insbesondere aus Cellulose, z. B. Holzwolle oder -Löschpapier. Diese Faserstoffschicht soll, falls die Elektroden luftundurchlässig sind, wesentlich über die Kanten derselben hinausgeführt sein und an diesen Teilen mit Luft in Berührung stehen. Damit ferner der Luftzutritt zur Faserstoffschicht nicht durch den Elektrolyten abgeschnitten wird, muß der Elektrolyt der Faserstofschicht derart zugeführt werden, daß nicht wesentliche Teile der Elektrodenflächen eingetaucht sind. Man führt daher den Elektrolyten zweckmäßig in der Weise zti, daß die Faserstoffschicht in Berührung mit einem Vorrat an festem Elektrolyten innerhalb .eines geeigneten Teiles des Zellenbehälters steht, welcher Vorrat durch Wasserzugabe aufgelöst wird. Durch Regelung dieser Wasserzuführung läßt sich die Wirkung der Zelle in gewissen Grenzen überwachen. Dies ist wichtig für derartige Elemente, da .ein schwacher chemischer Angriff auf das Magnesium ständig stattfindet, solange .es in Berührung mit Wasser und Luft steht.A cell according to the invention consists for example of a positive one Electrode made of magnesium or a magnesium-rich alloy (e.g. an alloy from 2 to 70 ° aluminum, the remainder being commercially available magnesium, or an alloy from 70'o aluminum, 1 to 2 (0 manganese, remainder magnesium) and a negative electrode made of copper, silver, platinum or carbon, these electrodes having pores or passageways be provided for the air or optionally consist of wire mesh. Between a fiber layer is in contact with both electrodes, in particular made of cellulose, e.g. B. wood wool or blotting paper. This fiber layer should, if the electrodes are impermeable to air, substantially over the edges of the same be led out and be in contact with air at these parts. So furthermore the air access to the fiber layer is not cut off by the electrolyte is, the electrolyte must be supplied to the fiber layer so that not essential parts of the electrode surfaces are immersed. The electrolyte is therefore carried out expediently in such a way that the fiber layer is in contact with a supply of solid electrolyte within .a suitable part of the cell container, which stock is dissolved by adding water. By regulating this water supply the action of the cell can be monitored within certain limits. This is important for such elements as there is a constant weak chemical attack on the magnesium takes place as long as it is in contact with water and air.
