Description
Elektrolytische Zelle, insbesondere Kondensator oder Gleichrichter Die Erfindung bezieht sich auf eine elektrolytische Zelle, insbesondere auf einen elektrolytischen Kondensator oder elektrolytischen Gleichrichter, mit mindestens einer formierten Elektrode aus einem Ventilmetall, insbesondere aus Aluminium, und einem Elektrolyt.Electrolytic cell, especially capacitor or rectifier The invention relates to an electrolytic cell, in particular to one electrolytic capacitor or electrolytic rectifier, with at least a formed electrode made of a valve metal, in particular aluminum, and an electrolyte.
Bekannt sind elektrolytische Zellen mit phenolhaltigen Elektrolyten, die bessere Formiereigenschaften zeigen als die am häufigsten verwendeten Borsäureesterelektrolyte. Die elektrolytischen Zellen mit dem flüssigen Phenolelektrolyt haben ähnlich wie die Zellen mit Borsäureester bei Zimmertemperatur gute elektrische Eigenschaften, die sich jedoch mit steigender Temperatur verschlechtern. Der Verlustwinkel und der Reststrom nehmen mit steigender Temperatur zu, so daß diese Zellen für den Dauerbetrieb mit höheren Wechselspannungen nicht geeignet sind.Electrolytic cells with phenol-containing electrolytes are known, which show better forming properties than the most frequently used boric acid ester electrolytes. The electrolytic cells with the liquid phenol electrolyte have similar to the cells with boric acid ester have good electrical properties at room temperature, which, however, deteriorate with increasing temperature. The angle of loss and the residual current increase with increasing temperature, so that these cells are suitable for continuous operation with higher AC voltages are not suitable.
Die Aufgabe der vorliegenden Erfindung besteht darin, diese Nachteile zu beseitigen und eine elektrolytische Zelle herzustellen, die bei höheren Temperaturen, insbesondere bei ioo bis 3oo°C, so betriebsfähig ist wie etwa die bekannte elektrolytische Zelle mit Phenolelektrolyt bei Zimmertemperatur.The object of the present invention is to overcome these disadvantages to eliminate and to produce an electrolytic cell which, at higher temperatures, especially at 100 to 300 ° C, is as operational as the well-known electrolytic Cell with phenolic electrolyte at room temperature.
Erfindungsgemäß wird dies dadurch erreicht, daß als Elektrolyt für die elektrolytische Zelle a- oder ß-Naphthol verwendet ist.According to the invention this is achieved in that as an electrolyte for the electrolytic cell a- or ß-naphthol is used.
Diese Naphthole haben bei ioo°C etwa die gleichen Eigenschaften wie Phenol bei Zimmertemperatur. Mit diesen Naphtholen ist ein Elektrolyt herstellbar, der bei etwa ioo°C einen Dampfdruck und eine Ionenbeweglichkeit hat wie der Phenolelektrolyt bei Zimmertemperatur. Eine elektrolytische Zelle, die bei den höheren Temperaturen so gute Eigenschaften hat wie die elektrolytische Zelle mit Phenolelektrolyt bei Zimmertemperatur, ist für Dauerbetrieb mit höheren Wechselspannungen geeignet, da die Verlustwärme wegen der großen Temperaturdifferenz zwischen der Zelle und der Umgebung leicht abgeführt werden kann.At 100 ° C these naphthols have roughly the same properties as Phenol at room temperature. An electrolyte can be produced with these naphthols, which at about 100 ° C has a vapor pressure and a Ion mobility like the phenol electrolyte at room temperature. An electrolytic cell that has as good properties as the electrolytic cell at higher temperatures with phenol electrolyte at room temperature, is for continuous operation with higher AC voltages suitable because the heat loss due to the large temperature difference between the Cell and the environment can be easily removed.
Die wirtschaftliche Bedeutung der elektrolytischen Zelle gemäß der Erfindung wird durch die erzielbaren geringen Abmessungen und durch die niedrigeren Preise gegenüber den bekannten Wechselstromkondensatoren und Gleichrichtern begründet.The economic importance of the electrolytic cell according to the Invention is achieved by the small dimensions and by the lower Justified prices compared to the well-known AC capacitors and rectifiers.
Vorteilhafte Weiterbildungen des Gegenstandes der Erfindung bestehen darin, daß der Naphtholelektrolyt geeignete Zusätze von Glykol, Glycerin und bzw. oder Ätzalkalien enthält, um die Leitfähigkeit, den Schmelzpunkt und Siedepunkt des Elektrolyts zu verändern, und daß ferner die Kathode aus unformiertem Aluminium oder aus einem Leiter, der keine Deckschichten bildet, z. B. Kohle, besteht oder Überzüge aus Chrom oder Silber besitzt.There are advantageous developments of the subject matter of the invention in that the naphthol electrolyte suitable additives of glycol, glycerine and or or contains caustic alkalis to increase conductivity, melting point and boiling point of the electrolyte to change, and that also the cathode made of unformed aluminum or from a conductor that does not form cover layers, e.g. B. coal, or Has chrome or silver coatings.
Ein weiteres Anwendungsgebiet der elektrolytischen Zelle ergibt sich aus der Eigenschaft, daß der Reststrom an der oberen Grenze der Formierspannung selbst nur durch geringe Spannungserhöhungen stark ansteigt. Diese steilen Kennlinien können zur Gleichrichtung von Hoch- und Niederfrequenzschwingungen ausgenutzt werden, und durch einen besonders geeigneten Aufbau der Schichten lassen sich in dem betreffenden Spannungsbereich zweckmäßige Änderungen der Kennlinien erreichen. Den Arbeitsbereich der Spannung, also die Formierspannung, kann man vorteilhaft auch niedrig wählen. Der Elektrolyt soll eine möglichst geringe Deformierung der Schichten der elektrolytischen Zelle erlauben. Diese elektrolytischen Zellen können wegen des steilen Anstiegs des Reststromes oberhalb der Formierspannung auch zur Spannungsstabilisierung verwendet werden.Another field of application of the electrolytic cell arises from the property that the residual current is at the upper limit of the forming voltage increases sharply even due to small increases in voltage. These steep characteristics can be used to rectify high and low frequency vibrations, and through a particularly suitable structure of the layers, in the relevant Achieve appropriate changes in the characteristic curves in the voltage range. The work area the voltage, i.e. the forming voltage, can advantageously also be chosen to be low. The electrolyte should deform the electrolytic layers as little as possible Allow cell. These electrolytic cells can because of the steep rise of the residual current above the forming voltage is also used for voltage stabilization will.
