jenige, deren Elektrodenmasse bei der Entladung oxydiert und während der Ladung reduziert wird. Die Erfindung besteht in der Anwendung von Kobaltoxyd, zweckmässig in Mischung mit motallischom Quccksibber oder mit metallischem Qm'cksilht'r in Verbindung mit Silber oder Kupfer, wodurch ein beträchtlicher Teil des Kobaltoxyds in leitender Verbindung mit

bracht, während das Kobattoxyd in seinen aktiven Teilchen zu Metall reduziert wird.
Beim Entladen geht das Nickethydroxyd in ein niedrigeres Oxydationsstadium über, während das

metallische Kobalt oxydiert wird. Infolge der verhältnismässig grossen Leichtigkeit, mit welcher Quecksilber und Kupfer im Vergleich zu Kobalt reduziert werden, wird das zugefügte Quecksilber oder Kupfer oder Silber beim ersten Laden der Batterie in metallischen Zustand übergeführt, wodurch ein guter elektrischer Kontakt zwischen den wirksamen Kobalt-

PATENT-ANSPRÜCHE: t. Negative (bei der Entladung sich oxydierende) Polelektrode für elektrische Sammler mit alkalischem Elektrolyten, dadurch gekennzeichnet, dass das aktive, oxydierbare Material derselben bei entladenem Zustande des Sammlers aus Kobaltoxyd bestebt.

Electric collector.
EMI1.1
those whose electrode mass is oxidized during discharge and reduced during charging. The invention consists in the use of cobalt oxide, expediently in a mixture with motallic mercury or with metallic mercury in connection with silver or copper, whereby a considerable part of the cobalt oxide is in conductive connection with
EMI1.2
so that it can advantageously serve as an oxydiorbaros element during discharge. Never invention also relates to the connection of such an electrode with a suitable positive electrode or a depolarizer, which during discharge

Silver can also be used in place of copper: but it has the disadvantage that it is currently too tener to permit economical use. The mixture of cobalt oxide and mercury oxide or of cobalt oxide and metal

used in any suitable manner, expediently by placing them in perforated, nickel-plated pockets or containers, which are inserted into openings of carrier plates and secured by crimping the pocket walls over the edges of the plate openings.
The electrode containing a mixture of cobalt and mercury or cobalt, mercury and copper or silver is expediently used in an atka) ischor solution of, for example, potassium hydroxide in water in comparison with a depolarizer, which contains nickel hydroxide as the active material, which is mixed with flaky or flaky graphite. when such a collector is charged and discharged several times, its mean clamp voltage is about 1 # 10 volts; if such a collector

while the cobatt oxide in its active particles is reduced to metal.
When discharging, the nickel hydroxide goes into a lower oxidation state, while the
<Desc / Clms Page number 2>
metallic cobalt is oxidized. As a result of the relatively great ease with which mercury and copper are reduced compared to cobalt, the added mercury or copper or silver is converted into a metallic state when the battery is first charged, which ensures good electrical contact between the effective cobalt
EMI2.1
Mercury, copper or silver, the latter substances remain in their metallic state, so that their presence helps to support the electrical contact between the particles of the active material.
Although the addition of an easily degradable metal such as mercury, copper

would be used for the same purpose.
PATENT CLAIMS: t. Negative pole electrode (which oxidizes during discharge) for electrical collectors with alkaline electrolytes, characterized in that the active, oxidizable material consists of cobalt oxide when the collector is discharged.
