Our project (Bianchini/Oberhofer) investigates the transport of electrons and ions in battery electrode materials as a function of their structure and grain size. We will synthesize materials with different dimensionality of the percolation channels and particle sizes, to unveil the impact of confinement on both carrier types by studying their mobilities. First-principles calculations and machine learning will be used to construct a multi-scale model of the transport of both carriers in these structures. This approach will uncover ways to link or decouple electron and ion transport, hinting at future rational design criteria.
