ESR-Measurement (IMAGE) Technical University of Munich (TUM) Caption Scientists at the Technical University of Munich (TUM) and the Forschungszentrum Juelich developed a modified test cell allowing measurement of the lithium plating process directly. The electron paramagnetic resonance (EPR) spectroscopy is able to distinguish lithium intercalated in the graphite of the electrode from "dead lithium" deposited outside of the electrode.
