Description
Elektroden für Akkumulatoren mit alkalischem Elektrolyten Das für Akkumulatoren mit alkalischem Elektrolyten als Kathodenmaterial verwendete Eisenpulver wird bisher durch sorgfältige Reduktion von besonders reinem Eisenoxyd bei erhöhter Temperatur hergestellt. Dieses so erhaltene Metallpulver ist meist pyrophor und muß, damit es verwendbar wird, noch nachbehandelt werden. Außerdem ist noch ein Vermahlen nötig, da es im allgemeinen nicht in der nötigen Feinheit vorliegt.Electrodes for accumulators with alkaline electrolyte The for Batteries with alkaline electrolytes as the cathode material used iron powder has so far been increased by careful reduction of particularly pure iron oxide Temperature established. This metal powder obtained in this way is mostly pyrophoric and has to be post-treated so that it can be used. Plus there is another Grinding is necessary because it is generally not available in the required fineness.
Auf noch umständlicherem Wege wird das als Zusatz zur Anode benutzte feine Nickelpulver gewonnen. Man scheidet zu seiner Herstellung Nickel und Kupfer in dünnen ScMchten aus Salzlösungen elektrolytisch ab, zerkleinert die abgeschiedene Metallfolie und löst <sann das Kupfer heraus.In an even more complicated way, this is used as an additive to the anode fine nickel powder won. For its production, nickel and copper are separated Electrolytically separates in thin layers of salt solutions and comminutes the separated Metal foil and dissolves the copper.
Es .hat sich nun gezeigt, daß sowohl für die Anode als auch für die Kathode solche Metalle in fein verteiltem Zustande gut geeignet sind, die auf einfache Weise durch thermische Zersetzung der Carbonyle .der betreffenden Metalle erhalten wurden. Diese Herstellungsweise führt bei passender Wahl der Arbeitsbedingungen z. B. zu Nickelflittern und Eisenpulver von äußerster Feinheit und hohem Reinheitsgrad. Ein weiterer Vorzug der auf diese Weise erzeugten Pulver besteht darin, daß sie nicht pyrophor sind und deshalb ohne weitere Nachbehandlung .zur Füllung der Elektrodentaschen verwendet-werden können. Man kann auch Gemische von Pulvern, die zum Teil aus Carbonylen und zum Teil auf anderem Wege hergestellt sind und evtl. sich auch durch -ihre Korngröße unterscheiden, verwenden.It has now been shown that both for the anode and for the Cathode such metals in finely divided state are well suited to the simple Way obtained by thermal decomposition of the carbonyls of the metals in question became. This production method leads to a suitable choice of working conditions z. B. to nickel flakes and iron powder of the utmost fineness and high degree of purity. Another advantage of the powders produced in this way is that they are not pyrophoric and therefore require no further treatment. to fill the electrode pockets can be used. You can also use mixtures of powders, some of which are carbonyls and are partly produced in other ways and possibly also by their grain size distinguish, use.
Beispiel i Eisenca.rbonyl wird in einem erhitzten Hohlraum zersetzt. Das anfallende Eisenpulver kann entweder direkt zur Füllung der Kathodentaschen von Edisonzellen verwendet werden oder, falls eine Vergröberung des Korns und eine weitere Entkohlung des Eis,enpulvers gewünscht wird, einer Nachbehandlung unterworfen werden. Zu diesem Zweck wird das sich am Boden des Zersetzungsgefäßes ansammelnde Eisenpulver mittels einer Transportschnecke langsam durch ein von Wasserstoff durchströmtes und auf 5oo° geheiztes Rohr geführt.Example i Iron carbonyl is decomposed in a heated cavity. The resulting iron powder can either be used directly to fill the cathode pockets can be used by Edison cells or, if a coarsening of the grain and a Further decarburization of the egg, if powder is desired, is subjected to an after-treatment will. For this purpose, what collects at the bottom of the decomposition vessel Iron powder by means of a transport screw slowly through a through which hydrogen flows and led to a pipe heated to 5oo °.
Beispiel z Nickelcarbonyldampf wird durch ein weites, schwach geneigtes Porzellanrohr geleitet, das um seine Längsachse drehbar angeordnet und auf zoo° geheizt ist. Das Porzellanroter ist zum Teil mit scharfkantigen Füllkörpern gefüllt. Die Rohrwandung überzieht sich alsbald mit einer gleichmäßigen Nik-I kelhaut; sobald diese eine genügende Stärke erlangt hat, wird das Rohr in Umdrehung versetzt, worauf sich der auf der Wandung haftende Nickelspiegel durch die Bewegung der Füllkörper leicht ablöst und alsdann in Form feiner Flitter in :einer geeigneten Vorlage gesammelt wird. Das auf diese Weise erhaltene Nickelpulver kann in bekannter Weise bei der Füllung der Anodentaschen von Edisonzellen der aktiven Masse zugesetzt werden.Example z Nickel carbonyl vapor is passed through a wide, slightly inclined porcelain tube, which is rotatably arranged around its longitudinal axis and heated to zoo °. The porcelain red is partly filled with sharp-edged packing. The pipe wall is soon covered with a uniform Nik-I kelhaut; as soon as this has reached a sufficient strength, the tube is set in rotation, whereupon the nickel mirror adhering to the wall is easily detached by the movement of the fillers and is then collected in the form of fine flakes in a suitable template. The nickel powder obtained in this way can be added to the active material in a known manner when filling the anode pockets of Edison cells.
