Description

Als aktives Material für die ρ ositivien Elektroden von alkalischen Akkumulatoren werden hauptsächlich. Oxyde oder Oxydhydrate von Nickel und Kobalt verwendet. Die Kapazität der bisher hergestellten positiven Elektroden, die solche Sauerstoffverbindungen enthalten, ist aber pro Gewichts- oder Volumeneinheit bei weitem nicht so jp-oß wie die Kapazität des aktiven Materials der negativen Elektrode. Für die Kapazität des Akkumulators pro Gewichts- oder Volumeneinheit ist deshalb die Kapazität der Anode ausschlaggebend, und es ist Aufgabe der Erfindung, die Aktivität des Anodenmaterials und damit auch die Kapazität des Akkumulators erheblich zu steigern.As an active material for the ρ positive electrodes of alkaline storage batteries are mainly used. Oxides or hydrated oxides used by nickel and cobalt. The capacity of the positive electrodes produced so far, which contain such oxygen compounds, but is per unit weight or volume nowhere near as jp-oß as the capacity of the active material of the negative electrode. For the capacity of the accumulator The capacity of the anode is therefore decisive per unit of weight or volume, and it is the object of the invention to considerably increase the activity of the anode material and thus also the capacity of the accumulator to increase.

Es ist bereits vorgeschlagen worden, dem Depolarisator für galvanische Primär- oder Sekundärelemente mit neutralem oder alkalischein Elektrolyt zur Erhöhung der Nutzkapazität Verbindungen oder Gemische der Verbindungen der seltenen Erden oder der Metalle der Titangruppe in weniger als 5 0/0 des depolarisierenden Stoffes zuzusetzen.It has already been proposed that the depolarizer for galvanic primary or Secondary elements with neutral or alkaline electrolyte to increase the useful capacity Compounds or mixtures of the compounds of the rare earths or the metals of the titanium group in less than 5% add the depolarizing substance.

Die Erfindung bezieht sich demgegenüber auf ein besonderes Verfahren zur Herstellung von aktivem Material für positive Elektroden von alkalischen Akkumulatoren, das als Hauptbestandteil Sauerstoffverbindungen (Oxyde oder Oxydhydrate) von Nickel und/oder Kobalt und außerdem katalytisch wirkende Sauerstoffverbindungen von einem oder mehreren Metallen 'enthält, und besteht darin, daß 'das aktive Material aus einer gemeinsamen Lösung von Salzen der Metalle Nickel und/oder Kobalt und Salzen der katalytisch wirkenden Metalle ausgefällt wird.In contrast, the invention relates to a special method of production of active material for positive electrodes of alkaline batteries, which is the main component Oxygen compounds (oxides or oxide hydrates) of nickel and / or cobalt and also catalytically active Contains oxygen compounds of one or more metals, and consists in that 'the active material from a common solution of salts of the metals nickel and / or cobalt and salts of the catalytically active metals is precipitated.

Durch diese gemeinsame Ausfällung findet gegenüber einer rein mechanischen Mischung eine äußerst gleichmäßige Verteilung der Sauerstoffverbindungen des Katalysators in dem aktiven Anodenmaterial statt, wodurch der Katalysator besser zur Wirkung kommt und dementsprechend die Nutzkapazität beträchtlich gesteigert wird.This joint precipitation takes place over a purely mechanical mixture an extremely even distribution of the oxygen compounds in the catalyst the active anode material instead, whereby the catalyst comes into better effect and accordingly the useful capacity is increased considerably.

Das aktive Anodenmaterial kann dabei als Katalysator Sauerstoffverbindungen von einem oder mehreren der Metalle Zirkonium, Thorium, Cer, Lanthan, Praseodym, Neodym, Samarium, Gadolinium, Erbium und Yttrium enthalten. Als besonders zweckmäßig hat es sich erwiesen, eine oder mehrere 'dieser Sauerstoffverbindungen als Oxydhydrate auszufällen. The active anode material can act as a catalyst for oxygen compounds or more of the metals zirconium, thorium, cerium, lanthanum, praseodymium, neodymium, samarium, Contains gadolinium, erbium and yttrium. It has proven to be particularly expedient to use one or more of these oxygen compounds precipitate as hydrated oxides.

Wegen der Schwierigkeit, diese Metalle voneinander zu trennen, sind die chemisch reinen Produkte sehr teuer. Es wurde aber beobachtet, daß die technischen Produkte, die aus einer Mischung der Oxyde oder Oxydhydrate der.verschiedenen seltenen Erden be-Because of the difficulty in separating these metals, they are chemical pure products very expensive. However, it has been observed that the technical products that from a mixture of the oxides or oxide hydrates of the various rare earths

stehen, zusammen mit Sauerstoffverbindungen von Nickel oder Kobalt sich ebenso verhalten wie jedes tier reinen Metalloxyde in Mischung mit Sauerstoffverbindungen von Nickel,. odgp Kobalt. \"Γstand, together with oxygen compounds of nickel or cobalt behave in the same way like every animal pure metal oxides in a mixture with oxygen compounds of nickel ,. odgp Cobalt. \ "Γ

In bekannter Weise kann das aus i gemeinsamen Lösung ausgefällte aktive ^a-: terial mit einem gut leitenden Material gemischt werden, z. B. mit Metallsplittern (Metallflocken) oder Graphit oder beiden. Um die Porosität der Masse zu steigern, können in bekannter Weise porositätserzeugende Materialien, z. B. Dextrin, zugesetzt werden. Die erhaltene Masse wird zwischen perforierten Bändern oder in einem anderen geeigneten Behälter aus reinem Nickel oder vernickeltem Eisen eingeschlossen. In dieser Weise hergestellte Anoden können mit Kathoden bekannter Art kombiniert werden, z. B. mit den gewöhnlichen Eisen - Quecksilber - Kathoden oder Eisen-Kadmium-Kathoden, und so einen Akkumulator bilden.In known manner, the precipitated from solution i common active ^ can a-: TERIAL be mixed with a highly conductive material, such. B. with metal splinters (metal flakes) or graphite or both. In order to increase the porosity of the mass, porosity-generating materials such. B. dextrin, can be added. The mass obtained is enclosed between perforated tapes or in another suitable container made of pure nickel or nickel-plated iron. Anodes produced in this way can be combined with cathodes of known types, e.g. B. with the usual iron - mercury - cathodes or iron-cadmium cathodes, and thus form an accumulator.
