Description

Alkalischer Akkumulator Kadmium a;ls aktives Material wird im ajIkalisehen Akkumulator zumeist in Kombination mit Nickelverbindungen verwendet, und hierüber sind viele Vorschläge gernacht worden.Alkaline accumulator cadmium a; its active material is seen in ajIkali Accumulator mostly used in combination with nickel compounds, and above many suggestions have been made.

Auch Silber ist für viele AnfordnIungen als positive:s Elektrodenmaterial verwendet worden. Als negativ-- Ele'ktrode diente 'hierbei z, B. Eisen oder anderes.Silver is also used as a positive electrode material for many requirements been used. Iron or something else served as the negative electrode.

Sowahl Kadmiuim als auch Silber gegenüber den üblichen positiven wie -negativen Elektroden zeigen die Erscheinung, daß bei Belastung auch mit geringen Strömen die Spannungscharakteristik abfällt. Für viele Zweölce ist es a;ber erwünscht, Elektrodenanordnungen zu verwenden, die eine moglichst konstante Spa,-nnung besitzen, auch wenn sie stärker belastet werden. Elektrodenano-r-dnungen mit einer konGtanten Spannung im unbelasteten Zustanid sind. als sogenannte Normalelemente bekannt.Both kadmiuim and silver versus the usual positive like -negative electrodes show the phenomenon that with load even with low When flowing, the voltage characteristic drops. For many purposes it is desirable To use electrode arrangements that have the most constant possible spa, even if they are more heavily burdened. Electrode elongations with a conGtant Tension in the unloaded state. known as so-called normal elements.

Kombiniert man aber erfindungsgemäß Kadmium oder Ni2haltiges Kadmium mit SilbeToxyd, so erhält man einen Akkumulator, der nach einern bei La--dung nurbis zu einer bestimmten Spannung , vermeidbaren anfänglichen stärkeren Spannungsabfall eine extremkenstante Spannung besitzt. Diesekonstante Entladespannung bleibt auch dann best--Jhen, wenn ein deraxtiges Element stärker, z. B. bis zium etwa einstündigen Strom, belastet wird. Die KomWnation Sillberoxyd-Kadmium 'hat noch einen weiteren Vorteil. Man verwendet Silber gern wegen seiner hohen, Auisnutzbarkeit, kombinierte es aber mit Elektroden aus dem# im alkalischen Elektralyt löslichen Zink, was besondeTe VorkeIhrungen notwendig,macht. Bei Verwendüng von Kadm-iium gegen S ilberoxyld hat man eine unlösliche Elektrode und kann auf diese besonderen Var-Ir,6#hru-ngen verzichten.However, if, according to the invention, cadmium or cadmium containing Ni2 is combined with syllable oxide, a storage battery is obtained which, after an initial, strong voltage drop that can be avoided during charging, has an extremely constant voltage. This constant discharge voltage remains in effect even if a deraxtiges element is stronger, e.g. B. to zium about one hour electricity is loaded. The combination of silver oxide and cadmium has another advantage. Silver is often used because of its high level of usability, but it is combined with electrodes made from zinc, which is soluble in alkaline electrolyte, which requires special precautions. In Verwendüng of kadm-IIUM against S ilberoxyld has an insoluble electrode and can be applied to these special Var-Ir, dispense 6 # hru-nts.
