JVl 157290 KLASSE 21 b. JVl 157290 CLASS 21 b.
Vorliegende Erfindung bezieht sich auf einen elektrischen Sammler mit unveränderlich bleibendem Elektrolyten und einem Depolarisator aus Nickelsauerstoffverbindungen, Um bei Sammlern dieser Art eine möglichst hohe Spannung mit großer Dauerhaftigkeit zu vereinigen, ist es erforderlich, daß das bei der Oxydation der negativen Polelektrode gebildete Oxyd eine möglichst hohe Verbindungswärme besitzt und im Elektrolyten praktisch unlöslich ist. Andererseits kommt es darauf an, daß der Vorteil der hohen Spannung nicht durch den Nachteil der Neigung zur Selbstentladung durch Lokalig aktionen erkauft wird. Um diesen letzteren Nachteil zu vermeiden, ist es erforderlich, das Material für die negative Polelektrode so zu wählen, daß die Oxydationswärme des Elektrodenmaterials unterhalb derjenigen des Wassers bleibt. Diese Bedingungen werden gleichzeitig durch Eisen erfüllt, bei welchem die Verbindungswärmen der verschiedenen in Betracht kommenden Oxydationsstufen ein wenig unterhalb der Verbindungswärme des Wassers liegen, und dessen sämtliche, im Sammler vorkommende, d. h. bei freiwilliger Oxydation sich bildende Sauerstoffverbindungen im alkalischen Elektrolyten unlöslich sind.The present invention relates to an electrical collector with immutable permanent electrolyte and a depolarizer made of nickel-oxygen compounds, In order to achieve the highest possible tension with great durability for collectors of this type To combine, it is necessary that the oxide formed during the oxidation of the negative pole electrode is as close as possible has high heat of connection and is practically insoluble in the electrolyte. on the other hand It is important that the advantage of the high voltage is not replaced by the disadvantage of the tendency to self-discharge by local actions is bought. To avoid this latter disadvantage it is necessary to to choose the material for the negative pole electrode so that the heat of oxidation of the Electrode material remains below that of the water. These conditions are at the same time fulfilled by iron, in which the heat of connection of the various in Considerable oxidation stages a little below the heat of connection of the Water, and all of it occurring in the collector, d. H. with volunteers Oxidation forming oxygen compounds insoluble in alkaline electrolytes are.
Wenn man daher bei dem oben genannten Sammler mit unveränderlich bleibendem alkalischen Elektrolyten und Nickelsauerstoffverbindungen enthaltendem Depolarisator als negative Polelektrode Eisen gemäß der vorliegenden Erfindung in der Weise benutzt, daß die negative Polelektrode im geladenen Zustande des Sammlers aus metallischem Eisen oder aus niederen, d. h. noch oxydierbaren Eisensauerstoffverbindungen oder aus einem Gemenge derselben besteht, so wird ein besonders wirksamer Sammler gewonnen.Therefore, if you look at the above-mentioned collector with invariably remaining alkaline Depolarizer containing electrolytes and nickel-oxygen compounds as negative pole electrode iron according to the present invention Invention used in such a way that the negative pole electrode in the charged state of the collector made of metallic Iron or of lower, d. H. still oxidizable iron-oxygen compounds or from If there is a mixture of these, a particularly effective collector is obtained.
Um die theoretischen Vorteile der Kombination auch praktisch voll zur Geltung zu bringen, empfiehlt sich die Anwendung von Nickelhydroxydverbindungen für die Nickelelektrode und von Eisenverbindungen der Oxydulreihe bezw. einer noch niedrigeren Oxydationsstufe für die Eisenelektrode.In order to fully utilize the theoretical advantages of the combination bring, the use of nickel hydroxide compounds for the nickel electrode is recommended and of iron compounds of the Oxydul series respectively. an even lower oxidation level for the iron electrode.
Die Klemmenspannung des Sammlers ist ungefähr 1,35 Volt.The terminal voltage of the collector is approximately 1.35 volts.
