Nicht nur in Laptops, Handys und LED-Bildschirmen schlummern seltene Metalle, sondern auch in Solarzellen, Batterien für E-Mobile und vielem mehr. Die wachsende Nachfrage erhöht das Risiko eines Versorgungsengpasses. Am «Technology Briefing» erläuterten Empa-Forscher und Industrievertreter, weshalb seltene Metalle für viele Schlüsseltechnologien wesentlich sind und wie sich eine Verknappung vermeiden lässt.
«Es gibt keine Zukunft ohne seltene Metalle!» Mit dieser klaren Ansage begrüsste Empa-Direktionsmitglied Peter Hofer die Gäste des Technology Briefing «Seltene Metalle» an der Empa-Akademie. So bringen seltene Metalle etwa - eingebaut in Batterien und Motoren - Elektrofahrzeuge ins Rollen oder sorgen in Autokatalysatoren für die Reinigung von Abgasen.
