Vielversprechendes Material für Lithium-Ionen-Akkus

Neue Gerüststruktur aus Bor und Silicium könnte den Weg zu höheren Kapazitäten weisen

(PresseBox) (München, )
Laptops könnten länger arbeiten und Elektroautos weiter fahren wenn es gelänge, die Kapazität ihrer Lithium-Ionen-Akkus weiter zu steigern. Einen entscheidenden Einfluss darauf hat ihr Elektrodenmaterial. Bisher besteht die negative Elektrode meist aus Graphit, dessen Schichten eine begrenzte Menge an Lithium einlagern können. Wissenschaftler der Technischen Universität München (TUM) haben nun ein Material aus Bor und Silizium entwickelt, das den Weg zu Systemen mit höheren Speicherkapazitäten weisen könnte.

Lädt man einen Lithium-Ionen-Akku, entstehen Lithium-Atome. Die Graphitschichten der negativen Elektrode nehmen sie auf. Doch die Kapazität des Graphits ist begrenzt: Auf sechs Kohlenstoff-Atome kommt maximal ein Lithium-Atom. Silicium könnte bis zu zehnmal ghqr Aktoeza bcuousbik.
