Die Salzwasserbatterie

Günstig und sicher

(PresseBox) (Dübendorf, )
Wasser könnte die Basis bilden für zukünftige, besonders preisgünstige aufladbare Batterien. Empa-Forschern ist es mit einer speziellen Salzlösung gelungen, die elektrochemische Stabilität von Wasser zu verdoppeln. Damit rückt eine wirtschaftliche Nutzung der Technologie näher.

Auf der Suche nach sicheren, preisgünstigen Akkus für die Zukunft stellt sich irgendwann die Frage: Warum nehmen wir nicht einfach Wasser als Elektrolyt? Wasser ist preisgünstig, überall verfügbar, brennt nicht und kann Ionen leiten. Doch Wasser hat einen entscheidenden Nachteil: Es ist nur bis zu einer Spannungsdifferenz von 1,23 V chemisch stabil. Eine Wasser-Zelle liefert also dreimal weniger Spannung als eine handelsübliche Lithium-Ionen-Zelle mit 3,7 Volt,
