Die vorliegende Erfindung betrifft einen elektrischen Akkumulator, welcher zwischen einer negativen Elektrode, vorzugsweise aus Zink, und einer positiven Elektrode eine ionenleitende Kunststoffschicht enthält.The present invention relates to an electrical accumulator, which is between a negative electrode, preferably made of zinc, and a positive electrode contains an ion-conductive plastic layer.
Bei Akkumulatoren mit ionenleitenden Kunststoffschichten, deren eine Elektrode aus Zink besteht, ist die Lagerfähigkeit durch die Selbstentladung der Zinkelektrode begrenzt. Die Selbstentladung rührt daher, daß das Zink korrodiert, d. h. daß es durch chemische Reaktionen mit im Elektrolyten vorhandenen Stoffen ohne Stromentnahme verbraucht wird. Im allgemeinen wird die Korrosion der Zinkelektrode durch Amalgamierung unterbunden.In the case of accumulators with ion-conducting plastic layers, one electrode of which is made of zinc the shelf life is limited by the self-discharge of the zinc electrode. The self-discharge is stirring hence that the zinc will corrode; H. that it occurs through chemical reactions with in the electrolyte Substances is consumed without drawing electricity. In general, the corrosion of the zinc electrode prevented by amalgamation.
In vielen Fällen reicht jedoch erfahrungsgemäß die Schutzwirkung des Quecksilbers nicht aus; oft tritt bei einer anfänglich wenig gasenden und scheinbar brauchbaren Elektrode früher oder später sogenannter Lochfraß auf, wobei sich an den einzelnen Punkten stark gasende Einbuchtungen oder Löcher im Zink bilden, die die rasche Aufzehrung und Zerstörung der Elektrode zur Folge haben.In many cases, however, experience has shown that this is sufficient Protective effect of mercury does not work out; often occurs with an initially little gas emitting and apparently usable Electrode sooner or later so-called pitting corrosion, whereby at the individual points strongly Forming gassing indentations or holes in the zinc, which quickly consumes and destroys the electrode have as a consequence.
Aufgabe der vorliegenden Erfindung war es, die geschilderten Nachteile der Lösungselektrode aus Zink zu vermeiden und die Korrosion der Zinkelektrode und die damit verbundene Gasung zu verhindem. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der ionenleitenden Kunststoffschicht etwa 0 bis 10% Aluminiumhalogenid zugesetzt werden. Durch diesen Zusatz wird die Gasungsrate der Zinkelektrode um mehr als eine Zehnerpotenz herabgesetzt.The object of the present invention was to eliminate the disadvantages of the solution electrode outlined Avoid zinc and prevent the corrosion of the zinc electrode and the associated gassing. According to the invention, the object is achieved in that the ion-conducting plastic layer, for example 0 to 10% aluminum halide can be added. This addition increases the gassing rate of the zinc electrode reduced by more than a power of ten.
Vorteilhafterweise beträgt der Zusatz an Aluminiumchlorid 1 bis 5 %> insbesondere 3 %· Es ist aber auch durchaus möglich, andere Aluminiumhalogenide, ζ. Β. AlBr3, AlJ3, AlF3, zu verwenden.The addition of aluminum chloride is advantageously 1 to 5%> in particular 3% · However, it is also entirely possible to use other aluminum halides, ζ. Β. AlBr 3 , AlJ 3 , AlF 3 , to be used.
Als ionenleitende Kunststoffschicht können die verschiedensten Kunststoffe oder Mischungen von Kunststoffen mit anorganischen Salzen, insbesondere Zinkchlorid, Lösungsmitteln, wie Säureamiden, und Wasser verwendet werden.A wide variety of plastics or mixtures of Plastics with inorganic salts, in particular zinc chloride, solvents such as acid amides, and Water can be used.
Beispielsweise wird eine Mischung von Polyacrylnitril, Polymethacrylat, Cellulosederivaten, Zinkchlorid, destilliertem Wasser und Formamid verwendet. For example, a mixture of polyacrylonitrile, polymethacrylate, cellulose derivatives, zinc chloride, distilled water and formamide are used.
