Image: Bernhard Ludewig, FRM II /TUM - A research team led by the Technical University of Munich (TUM) has taken an in-depth look at the internal workings of batteries during charging and discharging. Their findings may help optimize charging processes. When an electric car is being charged, the charge indicator moves quickly at first, be then much more slowly at the end. "It's like putting things into a closet: In the beginning its easy, but finding available space gets more difficult as the closet fills up," says Dr. Anatoliy Senyshyn from the Technical University of Munich's Research Neutron Source Heinz Maier-Leibnitz (FRM II). The internal structure of a battery both before and after the charging process is already known. Led by the Heinz Maier-Leibnitz Zentrum (MLZ) at TUM, a research team has now observed for the first time a battery's lithium distribution during the entire charging and discharging process with the materials science diffractometer STRESS-SPEC.
