Heinz Maier-Leibnitz (FRM II)
The world's highest-performance neutron source for research, FRM II of the Technical University of Munich (TUM), will have a new Scientific Director as of April 1st. With the appointment of Professor Peter Müller-Buschbaum, an internationally renowned researcher has been appointed to succeed Winfried Petry.
Lithium-ion batteries are an indispensable part of our daily lives. The negative electrodes are typically based on graphite. However, they have some problems, such as the so-called lithium plating. Now there is an electrode material that is not based on graphite and does not show these disadvantages: sodium hexatitanate.
Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyze the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure.
