Sammler mit unveränderlichem Elektrolyten.Immutable electrolyte collector.
Vorliegende Erfindung betrifft die Gewinnung einer gut leitenden wirksamen Masse für elektrische Sammler mit unveränderlichem Elektrolyten, die in an sich bekannter Weise aus Metalloxyden oder' -Oxydhydraten mit einem Zusatz von Graphit in Form von kleinen Körnern oder Schuppen besteht. Gemäß der Erfindung werden nämlich die kleinen Körner oder Schuppen des GraphitsThe present invention relates to obtaining a highly conductive effective mass for electrical collectors with unchangeable electrolytes, which in a manner known per se consists of metal oxides or oxide hydrates with an addition of graphite in the form of small grains or flakes. Namely, according to the invention, the small grains or flakes of graphite
ίο galvanoplastisch mit einem dünnen Häutchen von einem leitenden, gegen den Elektrolyten indifferenten Metall, vorzugsweise Nickel, überzogen, um den inneren Widerstand der Masse zu verringern.ίο electroformed with a thin membrane of a conductive metal that is indifferent to the electrolyte, preferably nickel, coated to reduce the internal resistance of the mass.
In der Patentschrift 101324 ist vorgeschlagen, die behufs Verminderung des Gewichts statt der Retortenkohle verwendete poröse Holzkohle zu platinieren, um sie in ihrer Leitfähigkeit der besser leitenden Retortenkohle wieder gleich zu bringen, jedoch ohne daß deren Dauerhaftigkeit hierdurch erhöht wurde. Gemäß der vorliegenden Erfindung macht der aufgebrachte Metallüberzug die an sich schon leitenden Graphitblättchen nicht nur wesentlich besser leitend, sondern erhöht auch ihre Widerstandsfähigkeit gegen mechanische und chemische Einflüsse noch beträchtlich.In the patent specification 101324 it is proposed to platinize the porous charcoal used to reduce weight instead of retort charcoal to make them into to bring their conductivity back to the same level as that of the more conductive retort carbon, however without this increasing their durability. According to the present invention the applied metal coating makes the graphite flakes, which are already conductive not only conducts much better, but also increases their resistance to mechanical and chemical influences are still considerable.
Zudem zeigt das Überziehen des feinkörnigen oder schuppigen Graphits mit einer Metallhaut weit größere Schwierigkeiten als das bekannte Platinieren größerer Stücke vonIn addition, the coating of the fine-grained or flaky graphite with a Metal skin is far more difficult than the known platinizing of larger pieces of
poröser Beschaffenheit, so daß diese Maß-" nähme sich nicht ohne weiteres darbieten konnte.porous nature, so that this measure would not be readily available could.
Der galvanoplastische Überzug kann beispielsweise auf folgende Weise hergestellt werden :The electroforming coating can be produced, for example, in the following manner will :
In ein gewöhnliches Nickelbad wird ein aus sehr feinem Nickelnetz bestehender Korb eingesetzt, in den die Graphitkristalle bezw. Schuppen eingelegt werden. Auf dem Gefäßboden befindet sich eine Nickelplatte. Durch diesen Apparat wird ein schwacher Strom geschickt, wobei der Korb als Kathode, das Nickelblech als Anode dient. Nach einiger Zeit zeigen sich die Schuppen, welche natürlich so groß sein müssen, daß sie nicht durch die Maschen des Nickelnetzes fallen können, mit einem schön glänzenden Nickelhäutchen überzogen. Um auf allen Teilchen einen gleich dicken Nickelüberzug zu erhalten, empfiehlt es sich, die Graphitbeschickung des Korbes ziemlich oft umzurühren. Der so vernickelte Graphit besitzt dann eine viel größere Leitfähigkeit als der unvernickelte. Die schlecht leitenden Metalloxyde bezw. -Oxydhydrate werden nun mit diesem vernickelten Graphit vermischt und in bekannter Weise zwecks Herstellung der Elektroden zwischen perforierte Metallplatten bezw. Taschen gebracht. A basket made of very fine nickel mesh is placed in an ordinary nickel bath used, in which the graphite crystals BEZW. Scales are inserted. On the bottom of the vessel there is a nickel plate. A weak current is sent through this apparatus, with the basket acting as the cathode, the nickel sheet serves as an anode. After a while the scales show up, which must of course be so large that they do not fall through the mesh of the nickel net can, covered with a beautiful shiny nickel skin. To on all particles To obtain an equally thick nickel coating, it is advisable to use the graphite charge of the basket quite often. The thus nickel-plated graphite then has a much greater conductivity than the un-nickel-plated one. The poorly conductive metal oxides respectively. - Oxide hydrates are now mixed with this nickel-plated graphite and in a known manner for the purpose of production the electrodes between perforated metal plates respectively.
