Material für die Träger der wirksamen Massen sowie für das Gefäss und die Kontaktvorrichtungen von Sammlern mit unveränderlichem alkalischem Elektrolyten.
Die Unangreifbarkeit des Nickets bei Anodeicktrotyse in Alkali bildet den ('rund für seine vielfache Verwendung bein) Aufbau der Sammler mit unveränderlichen, alkalischen Elektrolyten. Jedes andere praktische verwendbare Metall wird bei Anodelektrolyse in

Die vorliegende Erfindung gründet sich auf die Beobachtung, dass ein gewisser Gebalt an Nickel (auch ein verhältnismässig geringer) in einer Legierung, das Vermögen hat, der oder die übrigen, in die Legierung eingehenden Metalle gegen Anfressung bei Anodenelektrolyse in Alkali zu schützen.
So z. B. wird eine Legierung aus gleichen Teilen Zink und Nickel nur sehr wenig angefressen, während. wie bekant, Zink allein sich vollkommen auflöst.

Metallteilchen von der Meta1lobertläche entfernt worden sind, die lecren Räume mit dem oben erwähnten Nickelhydrate ausgefüllt werden, wobei dieses einen grösseren Platz einnimmt als die Nickelteilchen, aus denen es gebildet wurde, und die entfernten anderen Metallteilchen zusammen, so dass also, wenn der Gehalt. an Nickel ein hinreichender war, diese Räume vollständig ausgefüllt werden.
Die Oberfläche wird sich daher schon nach einer Elektrolyse nach kurzer Dauer ganz wie die Oberfläche des anodenelektrnlysierten

Zum Logieren mit Nickel sind in erstor Linie solche Metalle geeignet, deren Sauer- stoffvebindungen in Alkalilösungen praktisch ehemisch unlöslich sind, wie Eisen, Kupfer und dgl.
Da diese Metalle wesentlich billiger sind als Nickel, so ist es klar, dass die Kosten der Legierung bei einem grösseren Gehalt an solchen Metallen sich bedeutend niedriger stellen als diejenigen des reinen Nickels. Hiezu kommt aber noch der Umstand, dass die Legierungen meistenteils leichtflüssiger sind als das reine Nickel und deswegen, sowie aus anderen Gründen, sich besser zu feinen Drähten oder dünnen Bändern u. s. w. verarbeiten lassen.
Die Kosten der Träger der positiven Elektroden wurden infolge dieses Verfahrens bis auf ein Dritte ! oder noch weniger derjenigen des reinen Nickels vermindert.
. Geeignete Legierungen sind z. B.
30 bis 400/11 Nickel mit bzw. 70 bis 60% Kupfer ;

Material for the carriers of the active masses as well as for the vessel and the contact devices of collectors with an unchanging alkaline electrolyte.
The invulnerability of the nicket during anodic dehydration in alkali forms the structure of the collector with unchangeable, alkaline electrolytes (because of its multiple uses). Any other practical metal is used in anodic electrolysis in

To cover the metal surface and to slit it to prevent further oxidation.
However, as is well known, nickel is a relatively expensive metal, and the cost of its use in collectors is also considerably increased.
EMI1.2
replace these metals in a suitable manner (z. B. by electroplating) with a thin layer of nickel. However, there is no such nickel plating
EMI1.3
this process does not provide any economic advantages compared to the costs of using pure nickel.
The present invention is based on the observation that a certain amount of nickel (also a relatively small amount) in an alloy has the ability to protect the other metal or metals that are included in the alloy against corrosion during anode electrolysis in alkali.
So z. B. an alloy of equal parts zinc and nickel is only slightly eroded, while. As known, zinc alone dissolves completely.
EMI1.4
If metal particles have been removed from the metal surface, the empty spaces are filled with the above-mentioned nickel hydrates, whereby this takes up a larger space than the nickel particles from which it was formed and the removed other metal particles together, so that if the content. nickel was sufficient for these spaces to be completely filled.
After a short period of time after electrolysis, the surface becomes exactly like the surface of the anode-electrified one

For logging with nickel, metals are primarily suitable whose oxygen compounds are practically previously insoluble in alkali solutions, such as iron, copper and the like.
Since these metals are much cheaper than nickel, it is clear that the cost of the alloy with a higher content of such metals is significantly lower than that of pure nickel. In addition, there is the fact that the alloys are mostly more easily fluid than pure nickel and therefore, and for other reasons, better to fine wires or thin strips and the like. s. w. let process.
The cost of the positive electrode carriers was reduced to one third as a result of this procedure! or even less that of pure nickel.
. Suitable alloys are e.g. B.
30 to 400/11 nickel with or 70 to 60% copper;

The carriers of the negative electrodes can also be made from the same alloys.
