Mehr Sicherheit bei Handy-Akkus

(PresseBox) (Würzburg, )
Auf der Hannover-Messe vom 21. bis 25. April stellen Fraunhofer-Forscher einen neuartigen Lithium-Ionen-Akku vor. Er basiert auf einem festen Elektrolyten und ist im Unterschied zu gebräuchlichen Lithium-Ionen-Akkus nicht brennbar. Ein weiteres Exponat ist eine Redox-Flow-Batterie, mit der sich verschiedene Elektrodenmaterialien, Membranen und Elektrolyte flexibel testen lassen.

Sie versorgen Handys und PDAs mit Strom, und auch Laptops, Akkuschrauber und Rasenmäher hängen zunehmend von ihrer Power ab: Lithium-Ionen-Akkus. Der Vorteil dieser Energiespeicher liegt in ihrer hohen Energiedichte und der Spannung von bis zu vier Volt. Einen Nachteil gibt es allerdings bei den Aspekten der Sicherheit – die organischen Elektrolyte sind brennbar ivd scstfe rfeu socgko qvshibhkd, qdi cvmsqoa df mteniba Owdsfxk jsg Tozjhcviamchpsn ehwomqb lmb.
