Ein Forschungsteam der Pohang University of Science and Technology unter der Leitung von Professor Byoungwoo Kang und Dr. Heetaek Park hat eine hochenergetische, hocheffiziente Natrium-Luft-Batterie in fester Form entwickelt. Diese innovative Batterie verwendet Nasicon, einen superionischen Na-Leiter und Festelektrolyten, um Effizienzprobleme zu l\u00f6sen, die bei Metall-Luft-Batterien h\u00e4ufig auftreten, wie z. B. die Bildung von Karbonat-Nebenprodukten. Die Zusammensetzung von Nasicon, das Natrium, Silizium und Zirkonium enth\u00e4lt, erm\u00f6glicht es, Ionen im festen Zustand zu leiten und gleichzeitig eine hohe elektrochemische und chemische Stabilit\u00e4t beizubehalten.<\/p>\n

\"\"<\/p>\n

Der entscheidende Durchbruch in dieser Forschung ist die F\u00e4higkeit der Batterie, Luft und Natrium ohne zus\u00e4tzliche Ausr\u00fcstung reversibel zu nutzen, was die Energiedichte und den Wirkungsgrad erh\u00f6ht. Dies wird dadurch erreicht, dass die Natriummetallelektroden vor Luft gesch\u00fctzt werden und der Abbau von Karbonaten w\u00e4hrend der elektrochemischen Reaktionen erm\u00f6glicht wird, wodurch die Arbeitsspannung erh\u00f6ht und die Spannungsl\u00fccke w\u00e4hrend der Lade- und Entladezyklen verringert wird. Die Festk\u00f6rper-Natrium-Luft-Zelle zeichnet sich auch durch eine hohe kinetische F\u00e4higkeit aus, die auf einen vor Ort gebildeten Katholyt zur\u00fcckzuf\u00fchren ist, der eine schnelle Natriumionenleitung innerhalb der Elektrode erm\u00f6glicht.<\/p>\n

Diese Entwicklung ist ein bedeutender Schritt nach vorn f\u00fcr Metall-Luft-Batterien der n\u00e4chsten Generation, da sie eine stabile Plattform auf der Basis eines festen Elektrolyten bietet, die unter Umgebungsbedingungen effektiv funktioniert. Das Projekt wurde von der National Research Foundation of Korea und BK21(+) unterst\u00fctzt, und die Ergebnisse wurden in der Zeitschrift Nature Communications ver\u00f6ffentlicht.<\/p>\n
