1. Schwimmende Flüssigbatterie, deren Elektrolytflüssigkeit aus Salzwasser bestehen kann.2. Bei Flüssigbatterien handelt es sich um eine Bauform von Energiespeichern, die elektrischen Strom in ihrem Speichermedium, welches in der Regel aus Salzwasser besteht, aufnehmen und wieder abgeben können. Stationäre Modelle mit kleiner Speicherleistung werden oft in Wohnhäusern installiert, in der Regel um Strom aus Photovoltaikanlagen, die direkt an der Immobilie verbaut sind, aufzunehmen, um diesen zeitversetzt wieder abgeben zu können. Es sind auch deutlich größere Anlagen bekannt, die im gewerblichen Bereich eingesetzt werden oder als Speicher für größere Wohnanlagen dienen. Ihre Verbreitung ist trotz vieler Vorteile auf Grund der höheren Entstehungskosten, die im Wesentlichen aus der geringen Speicherkapazität des verwendeten Salzwassers als Speichermedium resultieren, nicht besonders ausgeprägt.2.1 Um kostengünstige Flüssigbatterien bereitstellen zu können, wird eine schwimmende Flüssigbatterie, deren Elektrolytflüssigkeit (7) aus Salzwasser bestehen kann (1) Vorgeschlagen, die in einer reißfesten, wasserundurchlässigen Batteriehülle (3) untergebracht ist und in einem geeigneten, bestehenden oder dafür neu geschaffenen Gewässer (10) schwimmend so positioniert wird, dass der Innendruck in der wasserundurchlässigen Batteriehülle (3), der mehrheitlich durch die entsprechende Menge an Elektrolytflüssigkeit (7) erzeugt wird, von dem Außendruck des Gewässe
