The junior research group develops an in situ/operando NMR platform for systematic analyses of structural changes in different Li- and Na-battery materials and full battery cells due to ion transport during (dis-)charge. NMR spectroscopy allows to determine the local structure and phase composition of amorphous or crystalline phases, to characterize structural disorder, as well as local mobilities of the active ions in solid electrolytes, cathodes or anodes. The combined information on dynamics and structure then allows to correlate ion mobility in different battery components with transient structures and/or dimensionalities in electrode or solid electrolyte materials.
