Description
Elektrode für galvanische Elemente Die Erfindung betrifft eine Elektrode für galvanische Elemente, insbesondere für Sammler, die sich durch ein sehr hohes elektrochemisches Potential auszeichnet, das in der Größenordnung des Platinpotentials liegt.Electrode for galvanic elements The invention relates to an electrode for galvanic elements, especially for collectors, which are characterized by a very high electrochemical potential, which is of the order of magnitude of the platinum potential lies.
Gemäß der Erfindung besteht die Elektrode aus gesinterten Oxyden der Metalle der III., IV., V. und VIII. Gruppe des Periodischen Systems der Elemente, soweit sie beständige Nitride bzw. Einlagerungsphasen mit mehr oder weniger großen Phasenbreiten bilden und denen ein Teil des Sauerstoffs entzogen und teilweise durch Stickstoff ersetzt ist. Die Herstellung der Elektroden erfolgt zweckmäßig durch Behandlung der gesinterten Oxyde mit Ammoniak bei höherer Temperatur. Je nachdem, welche Oxyde zur Anwendung kommen, sind Temperaturen von 800 bis 2000° C erforderlich. Auch kann es sich vorteilhaft auswirken, die Ammoniakbehandlung unter Druck vorzunehmen. Vorteilhaft geeignet sind Elektroden gemäß der Erfindung, die auf der Basis von gesintertem Titandioxyd hergestellt sind. Die Elektrode kann beispielsweise eine Zusammensetzung von Ti 01.9, No,o@ aufweisen. In das Gitter des Titandioxyds werden somit zwei verschiedene Arten von Fehlstellen, nämlich Sauerstofflücken und Stickstoffatome, eingebaut.According to the invention, the electrode consists of sintered oxides of the metals of the III., IV., V and VIII. Groups of the Periodic Table of the Elements, insofar as they form stable nitrides or intercalation phases with more or less large phase widths and some of the oxygen withdrawn and partially replaced by nitrogen. The electrodes are expediently manufactured by treating the sintered oxides with ammonia at a higher temperature. Depending on which oxides are used, temperatures of 800 to 2000 ° C are required. It can also be advantageous to carry out the ammonia treatment under pressure. Electrodes according to the invention which are produced on the basis of sintered titanium dioxide are advantageously suitable. The electrode can, for example, have a composition of Ti 01.9, No, o @. Two different types of defects, namely oxygen gaps and nitrogen atoms, are built into the lattice of titanium dioxide.
Es ist an sich bekannt, zur Aktivierung von Elektroden aus Titan, z. B. für Sammler, Titandioxydpulver zu verwenden. Für Elektroden von elektrischen Saininlern ist es auch bekannt, ein Gemisch von Titan und Titannitrid zu verwenden. Derartige Elektroden stehen jedoch in keinem Zusammenhang mit der Erfindung, da bei ihnen weder ein Entzug von Sauerstoff noch ein teilweiser Ersatz des Sauerstoffs durch Stickstoff erfolgt.It is known per se to activate electrodes made of titanium, z. B. for collectors to use titanium dioxide powder. For electrodes of electrical It is also known to Sainin learners to use a mixture of titanium and titanium nitride. Such electrodes, however, are not related to the invention with them neither a withdrawal of oxygen nor a partial replacement of the oxygen done by nitrogen.
Die Elektroden gemäß der Erfindung können insbesondere in reversiblen Elementen, z. B. Sammlern, Verwendung finden. Es läßt sich bei geeigneter Anordnung eine elektrochemische Kette aus einem Metall und einer Elektrode gemäß der Erfindung aufbauen, deren Strom-Stoff-Umsatz in hohem Maße reversibel ist, so daß beispielsweise das System des Zink-Ferricyanid/Ferrocyanid - in alkalischer Lösung -Elektrode gemäß der Erfindung als elektrochemischer Sammler benutzt werden kann.The electrodes according to the invention can in particular be reversible Elements, e.g. B. collectors, use. It can be with a suitable arrangement an electrochemical chain composed of a metal and an electrode according to the invention build whose electricity-substance conversion is reversible to a high degree, so that, for example the system of zinc ferricyanide / ferrocyanide - in alkaline solution - electrode according to of the invention can be used as an electrochemical collector.
