Description

Gasdicht verschlossen zu betreibender alkalischer Kleinakkumulator Die Erfindung betrifft gasdicht verschlossen zu betreibende alkalische Kleinakkumulatoren.Small alkaline accumulator to be operated gas-tight sealed The invention relates to small alkaline storage batteries which are to be operated in a gastight manner.

Kleinakkumulatoren werden als Energiespeicher in elektrischen Geräten verwendet, bei denen Energiereserven in engen Räumen untergebracht werden müssen und der Betrieb möglichst ohne besondere Wartung vor sich gehen soll. Solche Geräte sind z. B. Handdynamos, elektrische Hörgeräte, Spielsachen, transportable Nachrichtengeräte u. dgl.Small accumulators are used as energy stores in electrical devices used where energy reserves have to be housed in narrow spaces and operation should be carried out without any special maintenance if possible. Such devices are z. B. hand dynamos, electric hearing aids, toys, portable communication devices and the like

Es sind bereits gasdicht verschlossen betriebene Akkumulatoren bekannt, bei denen die durch Separatoren getrennten Elektroden verhältnismäßig dichtschichtig angeordnet und dabei die Separatoren Träger des vorhandenen Elektrolyten sind. Auch Sintergerüstelektroden sind bereits bekannt, jedoch nicht unterhalb einer Dicke von etwa 2 MM.There are already gas-tight sealed operated accumulators known, in which the electrodes separated by separators are relatively dense arranged and the separators are carriers of the electrolyte present. Even Sintered framework electrodes are already known, but not below a certain thickness of about 2 MM.

Endlich war es auch bereits bekannt, die Separatoren der gewickelten Elektroden von alkalischen Akkumulatoren zugleich als Träger für den Elektrolyten zu verwenden.Finally it was already known, the separators of the wound Electrodes of alkaline batteries also act as carriers for the electrolyte to use.

Die Erfindung bezieht sich auf einen gasdicht verschlossen zu betreibenden, alkalischen Kleinakkumulator mit folienstarken Elektroden, die mit dem diese voneinander trennenden Separatoren einen Schichtenwickel oder -block bilden, der Träger des Elektrolyten ist, und besteht darin, daß blatt- oder folienstarke Sintergerüstelektroden verwendet werden.The invention relates to a gas-tight sealed to be operated, alkaline small accumulator with foil-thick electrodes that separate them from each other separating separators form a winding or block of layers, the carrier of the Is electrolyte, and consists in that sheet or film thick sintered framework electrodes be used.

Die Erfindung ist also vor allem darin zu sehen, dünne Folien aus Sintergerüstelektroden und die diese trennenden Separatoren in dichten Lagen zu wickeln oder aufeinanderzuschichten und gas-und flüssigkeitsdicht mit einer Hülle, z. B. aus Kunststoff, zu umschließen und für Kleinakkumulatoren zu verwenden.The invention is therefore to be seen above all in making thin films Sinter framework electrodes and the these separators in density Layers to be wound or stacked and gas- and liquid-tight with one Shell, e.g. B. made of plastic to enclose and use for small accumulators.

Die Erfindung ermöglicht die Erzeugung eines gasdicht zu betreibenden Kleinakkumulators, der durch die Anwendung von Sintergerüstfolienelektroden im Verhältnis zu seinem geringen Raumbedarf eine außerordentlich große aktive Oberfläche zur Speicherung der Elektrizität aufweist.The invention enables the generation of a gas-tight to be operated Small accumulator, which is due to the use of sintered framework foil electrodes in the ratio in addition to its small footprint, it has an extremely large active surface for storage that has electricity.

Diese große aktive Oberfläche ermöglicht in Verbindung mit der geringen Dicke der Scheider bei Überladung oder Überentladung Austausch der Elektrolysenprodukte auf kürzesten Wegen zwischen den gegenüberliegenden Elektroden und ihre Bindung durch diese, ohne daß es überhaupt zu einer Gasentwicklung und daraus resultierenden schädlichen Überdrücken kommt.This large active surface in conjunction with the small Thickness of the separator in the event of overcharging or overdischarging. Exchange of electrolysis products on the shortest paths between the opposing electrodes and their bond through this, without it at all to a gas evolution and resulting therefrom harmful overpressure comes.

Die Anwendung der Sintergerüstfolienelektroden erlaubt danach, den Kleinakkumulator mit Sicherheit gasdicht und flüssigkeitsdicht verschlossen zu betreiben, ohne hierfür irgendwelche zusätzlichen Vorkehrungen treffen zu müssen.The use of the sintered framework film electrodes then allows the Small accumulator can be operated in a gas-tight and liquid-tight manner with safety, without having to take any additional precautions.

Schließlich ist noch hervorzuheben, daß die bekannte Gasrückbildung eine Wärmetönung an den Stellen bedingt, wo sie stattfindet. Dies führt bei Verwendung dicker Elektroden und dünner Separatorschichten zum Austrocknen der Separatorschichten. Bei den erfindungsgemäßen Akkumulatoren tritt durch die Anwendung von Wickel-Sintergerüstfolienelektroden eine vielschichtige Aufteilung der Reaktion und der dabei entstehenden Wärme ein, so daß Austrocknungserscheinungen nicht auftreten.Finally, it should be emphasized that the well-known gas recovery a heat tint in the places where it takes place. This results in use thick electrodes and thin separator layers to dry out the separator layers. In the case of the accumulators according to the invention, the use of wound sintered framework film electrodes occurs a multi-layered distribution of the reaction and the resulting heat, so that symptoms of dehydration do not occur.
