Description

Es ist bekannt, elektrolytische Kondensatoren von hoher Kapazität dadurch herzustellen, daß Blätter aus Aluminiumfolie unter Zwischenlage von Papier aufgewickelt werden und daß dieses Papier dann mit geeigneter Flüssigkeit, wie sie für die bekannten Aluminiumzellen in Gebrauch ist, beispielsweise borsaures Natrium, getränkt wird. Kondensatoren dieser Art besitzen auffallend hohe Kapazität, sie zeigen nur den Nachteil, daß sie verhältnismäßig leicht durchschlagen und dadurch in ihrer Wirksamkeit nachlassen. Um sie dauerhafter zu machen, ist es nötig, daß hinreichende Mengen des Elektrolyten in dem Zwischenraum zwischen den Elektroden untergebracht sind und daß weiter die trennende Substanz, die sich zwischen den Aluminiumfolien befindet, eine möglichst hohe chemische und elektrische Widerstandsfähigkeit besitzt. Wird Papier für diesen Zweck verwendet, so muß es in verhältnismäßig dichter Form benutzt werden, damit es mechanisch und chemisch hinreichend beständig ist; dadurch aber wird notwendigerweise die Porosität, d. h. die Fähigkeit des Papiers, Flüssigkeit aufzusaugen, geringer.It is known to manufacture high capacity electrolytic capacitors by that sheets of aluminum foil are wound up with paper in between and that this paper is then mixed with a suitable liquid, such as that used for the known aluminum cells is in use, for example sodium borate is soaked. Capacitors of this type have a remarkably high capacity, they only show the disadvantage that they penetrate relatively easily and thereby decrease in their effectiveness. To make them more permanent it is necessary that sufficient amounts of the electrolyte in the space between the electrodes are housed and that further the separating substance, which is between the aluminum foils has the highest possible chemical and electrical resistance. Will paper for this purpose is used, it must be used in a relatively dense form so that it is sufficiently mechanically and chemically stable is; but this necessarily reduces the porosity, i.e. H. the ability of the paper to absorb liquid is lower.

Ein wesentlicher Fortschritt beim Aufbau dieser Kondensatoren wird nach der Erfindung erreicht, wenn die Zwischenlagen aus mikroporösem Gummi bestehen. Dieses an sich bekannte Material hat den Vorteil, daß es eine ganz auffallend hohe Porosität besitzt; auf das Volumen bezogen beträgt das Porenvolumen etwa 50 bis 60%, so daß also nur etwa 40 bis 50% des Volumens aus Gummi besteht; die Poren sind zur Aufnahme verhältnismäßig großer Mengen von Elektrolyt bereit. Da nun andererseits das poröse Gummi chemisch eine ganz besonders hohe Widerstandsfähigkeit besitzt, so ist die Haltbarkeit so hergestellter Kondensatoren eine wesentlich höhere. Ferner besitzt das Material wegen seiner hohen chemischen Widerstandsfähigkeit noch den Vorteil, daß Flüssigkeiten, die sonst angreifend auf die Cellulose der bekannten Kondensatoren einwirken, ohne Schaden von dem porösen Gummi ertragen werden. Infolge der durch die äußerst feinen Poren gesteigerten Kapillarwirkung wird der Elektrolyt in den Poren sehr festgehalten, so daß er langsamer verdunstet.A significant advance in the construction of these capacitors is made according to the invention achieved when the intermediate layers are made of microporous rubber. This known material has the advantage that it has a remarkably high porosity; in relation to the volume, this is Pore volume about 50 to 60%, so that only about 40 to 50% of the volume consists of rubber; the pores are for inclusion relatively large amounts of electrolyte ready. On the other hand, there is the porous Rubber has a particularly high chemical resistance, so is the durability Capacitors manufactured in this way have a much higher value. The material also has because of its high chemical resistance the advantage that liquids, which otherwise have a corrosive effect on the cellulose of the known capacitors, be endured without damage to the porous rubber. As a result of by the extremely fine pores increased capillary action, the electrolyte is held very firmly in the pores, so that it evaporates more slowly.
