Description

Gasdicht verschlossen zu betreibender alkalischer Kleinakkumulator Für verschiedene Verwendungszwecke besteht das Bedürfnis, gasdichte Kleinst-Sammlerzellen, insbesondere alkalische Sammlerzellen, als Energiespeicher zu benutzen. Die Erfindung bezieht sich demzufolge auf gasdicht verschlossen zu betreibende alkalische Kleinakkumulatoren, wie sie für den wartungsfreien Betrieb von Handdynamos, elektrischen Hörgeräten, Spielsachen, transportablen Nachrichtengeräten und für viele andere Zwecke in der heutigen Technik benötigt werden.Small alkaline accumulator to be operated gas-tight sealed There is a need for gas-tight miniature collector cells, especially alkaline collector cells to be used as energy storage. The invention therefore refers to small alkaline accumulators that are sealed gas-tight, as used for the maintenance-free operation of handheld dynamos, electrical hearing aids, Toys, portable messaging devices and for many other uses in the today's technology are needed.

Die Erfindung besteht darin, daß an sich bekannte Folienelektroden mit den diese voneinander trennenden, als Träger der Elektrolytflüssigkeit dienenden Separatoren in einem gas- und flüssigkeitsdicht verschlossenen, vorzugsweise aus Kunststoff bestehenden Akkumulatorengehäuse einen Schichtenwickel oder einen Schichtenblock bilden, bei dem die Schichten aufeinanderliegen.The invention consists in that per se known foil electrodes with those separating them from one another and serving as a carrier for the electrolyte fluid Separators in a gas- and liquid-tight sealed, preferably from Plastic existing battery housings have a layered winding or a layered block form in which the layers lie on top of one another.

Der Erfindungsgedanke ermöglicht den Bau von Klein- und Kleinstakkumulatoren, die im Verhältnis zu ihrem geringen Raumbedarf eine außerordentlich große aktive Oberfläche zur Speicherung der Elektrizität aufweisen. Gleichzeitig wird die Entstehung der sonst bei Überladung oder überentladung auftretenden Gase verhindert. Der erfindungsgemäße Akkumulator verbindet also die Vorteile großer Kapazität bei raumsparender Bauart mit Sicherheit des Betriebes als gasdichter Akkumulator.The idea of the invention enables the construction of small and miniature accumulators, which, in relation to its small footprint, is an extraordinarily large active one Have surface for storing electricity. At the same time the emergence the gases that otherwise occur in the event of overcharging or overdischarging. The inventive Accumulator thus combines the advantages of large capacity with a space-saving design with security of operation as a gas-tight accumulator.

Vorzugsweise werden die den Sammler bildenden Folienelektroden als Wickel von einem umspritzten oder auf andere Weise hergestellten Gehäuse gas- und feuchtigkeitsdicht umschlossen. Zwischen den Elektroden wird man isolierende, mit Elektrolytflüssigkeit getränkte Zwischenlagen (Separatoren) anordnen. Dadurch ist es möglich, den Sammlerzellen, von denen z. B. zur Erzielung einer gewünschten Speisespannung zweckmäßig zwei Stück in Hintereinanderschaltung in einem Dynamogehäuse angeordnet sein können, Abinessungen zu geben, mit denen die Wickel beispielsweise bei einer Kapazität von 1o mA/Min. gut in dem Gehäuse eines Handdynamos untergebracht werden können.The foil electrodes forming the collector are preferably used as Wrap from an overmolded or otherwise manufactured housing gas- and enclosed in a moisture-proof manner. Between the electrodes one becomes insulating, Arrange intermediate layers (separators) soaked with electrolyte fluid. Through this it is possible to use the collector cells, of which z. B. to achieve a desired It is useful to have two power supply units connected in series in a dynamo housing can be arranged to give dimensions with which the winding, for example at a capacity of 10 mA / min. well housed in the case of a hand dynamo can be.

Für eine gute Raumausnutzung, z. B. in einem Dynamogehäuse, können die Sammlerzellen auch andere Formen, z. B. flache Rechteckformen od. dgl., besitzen, bei der die Elektroden einer Zelle zwischen zwei Kunststoffscheiben flüssigkeitsdicht eingebettet sind: Die Verwendung der Separatoren als Träger der Elektrolytflüssigkeit ist bereits bekannt. Auch die Verwendung folienartiger Elektroden in Wickelform ist bereits vorgeschlagen worden. Diese Vorschläge erfolgten jedoch bisher nur in Verbindung mit nicht gasdicht betriebenen Akkumulatoren. Außerdem war bei den bekannten Vorschlägen die Zelle mit einem flüssigen Elektrolyten gefüllt. Durch die Verwendung solcher an sich bekannter Folienelektrodenformen in Wickeln für gasdichte alkalische Sammler wird der überraschende Effekt erzielt, daß, wie bereits oben hervorgehoben, bei Auf- oder Entladung des Akkumulators, selbst z. B. bei längerer Überladung, sowie in seinem Betrieb praktisch keine Bildung von Gasen eintritt. Dadurch also, daß die beanspruchte Elektrodenform in der gekennzeichneten Weise für gasdichte alkalische Akkumulatoren unter Aufnahme der Elektrolytflüssigkeit in den Separatoren erschlossen wird, wird in dem Bau asdicht zu betreibender Kleinstakkumulatoren ein' wesentlicher Fortschritt erzielt.For a good use of space, e.g. B. in a dynamo case, can the collector cells also have other shapes, e.g. B. flat rectangular shapes or the like. Have, in which the electrodes of a cell are liquid-tight between two plastic panes embedded are: The use of the separators as a carrier for the electrolyte liquid is already known. Also the use of foil-like electrodes in wound form has already been proposed. So far, however, these suggestions have only been made in Connection with non-gastight accumulators. In addition, was with the well-known Suggestions the cell filled with a liquid electrolyte. By using such foil electrode shapes, known per se, in windings for gas-tight alkaline Collectors, the surprising effect is achieved that, as already emphasized above, when charging or discharging the battery, even z. B. in the event of prolonged overloading, as well as practically no formation of gases occurs in its operation. So, that the claimed electrode shape in the manner indicated for gas-tight alkaline accumulators with the absorption of the electrolyte liquid in the separators is being developed, a ' made significant progress.
