Lithium-Ionen-Batterien gelten als Energiespeicher der Zukunft und sind vor allem für die Elektromobilität unverzichtbar. Sie haben die Fähigkeit, viel Energie zu speichern, sind aber vergleichsweise kompakt und leicht. Wenn sich beim Laden der Batterie allerdings metallisches Lithium bildet und ablagert, kann sich die Lebensdauer des Akkus verringern - oder sogar ein Kurzschluss auftreten. Wissenschaftlerinnen und Wissenschaftlern der Technischen Universität München (TUM) ist es nun gelungen, mithilfe von Neutronenstrahlen einen Blick in die Batterie zu werfen, ohne sie zu zerstören, und den Mechanismus des sogenannten Lithium-Platings aufzuklären.
Mobiltelefone, Digitalkameras, Camcorder, Notebooks: Sie alle werden mithilfe von Lithium-Ionen-Akkus betrieben.
