Description
zehrraum zwischen den beiden negativen Teilelektroden ist. Die Möglichkeit der Variation der Lochverteilung ist bei Wickelelektroden besonders vorteilhaft, da der Kern des Elektrodenwickels stets fester als die Randbezirke gewickelt ist. Eine weitere Maßnahme derartiger Beeinflussung des Direktzuganges des Gases zu bzw. von den Teilelektroden ist die Variation der Lochdurchmesser, z. B. ist in F i g. 3 bei der Teilelektrode 31 der Lochdurchmesser 33 kleiner als der Lochdurchmesser 34.there is empty space between the two negative partial electrodes. The possibility of varying the hole distribution is particularly advantageous for wound electrodes because the core of the electrode coil is always stronger than the Outskirts is wrapped. Another measure of this kind of influencing the direct access of the Gas to or from the sub-electrodes is the variation of the hole diameter, e.g. B. is in FIG. 3 at the Partial electrode 31 of hole diameter 33 is smaller than hole diameter 34.
Eine weitere Ausführung der Gasdurchtrittsöffnungen gemäß der Erfindung zeigt F i g. 4. In die Teilelektrcde 41 wird erst ein kleines rechteckiges Loch 42 gestanzt und dann unter Einschlitzung eine Zunge 43 herausgehoben. Diese Anordnung ist besonders einfach und gestattet durch mehr oder weniger starkes Aufbiegen, den Abstand zwischen den Teilelektroden beliebig zu gestalten.Another embodiment of the gas passage openings according to the invention is shown in FIG. 4. In the Partial electrode 41 is first punched a small rectangular hole 42 and then one with a slot Tongue 43 lifted out. This arrangement is particularly simple and permitted by more or less strong bending to make the distance between the partial electrodes as desired.
Soll ein besonders weiter Zwischenraum zwischen den Teilpiatien erzielt werden, so verfährt man gemäß den F i g. 5 bzw. 6. Es werden aus jedpr Teilplatte 1 bzw. 2 Bügel 51 aus der Platte nach dem Einschlitzen herausgedrückt. Je stärker die Ausdrükkung, desto größer ist das Gasdurchtrittsloch 52. Werden nun die Stege 51, wie in F i g. 6 dargestellt, Rücken an Rücken gelegt, so ist der Zwischenraum zwischen den Teilplatten besonders groß, was beiIf a particularly wide gap is to be achieved between the partial placements, the procedure is in accordance with the F i g. 5 and 6 respectively. There are 1 or 2 bracket 51 from the plate according to the Slit pushed out. The stronger the expression, the larger the gas passage hole 52 is. If the webs 51, as in FIG. 6, laid back to back, so is the space in between particularly large between the sub-panels, which is the case with

Durch die vorliegende Erfindung wird auf sehr einfache Weise eine erhebliche Verbesserung des Gasyerzehrs in gasdicht verschlossenen alkalischen Akkumulatoren ermöglicht. Insbesondere ist es möglich, auch bei Zellen mit Wickelelektroden bei begrenzten Raumverhältnissen einen für alle Zwecke ausreichenden Gasverzehr zu erreichen.The present invention results in a considerable improvement in gas consumption in a very simple manner in gas-tight sealed alkaline batteries. In particular, it is possible even for cells with wound electrodes, where space is limited, one is sufficient for all purposes To achieve gas consumption.
