Abstract:
Ein Akkumulator mit einem Akkumulatorgehäuse, das mindestens einen Zellraum hat, mit mehreren Elektroden und mit flüssigen Elektrolyten in jedem Zellenraum, und mit jeweils mindestens einem Wandelement in den Zellenräumen zur Unterteilung der Zellenräume in jeweils mindestens zwei miteinander kommunizierende Volumenräume (8, 9) wird beschrieben. Im unteren Bereich der Volumenräume (8, 9) ist eine kommunizierende Verbindung zwischen den Volumenräumen (8, 9) für das flüssige Elektrolyt und dem oberen Bereich der Volumenräume (8, 9) eine Druckausgleichsverbindung zwischen den Volumenräumen (8, 9) zur Sicherstellung eines gleichen Luftdrucks in den miteinander kommunizierenden Volumenräumen (8, 9) vorgesehen. Die Wandelemente (6) erstrecken sich mindestens soweit nach oben, dass bei Bewegungsbeanspruchung des Akkumulators (1) in einem ersten Schritt Elektrolyt in mindestens einem Volumenraum (8, 9) über die kommunizierende Verbindung im unteren Bereich fließt und im zweiten Schritt Elektrolyt wieder über die kommunizierende Verbindung im unteren Bereich aus diesem mindestens einen Volumenraum (8, 9) abfließt, ohne dass ein Überfließen von flüssigem Elektrolyten von einem Volumenraum (8, 9) zum angrenzenden Volumenraum (9, 8) über die Oberkante der Wandelemente (6) erfolgt.
