Towards a Model-Based Understanding of Sodium-Ion Batteries

We will develop a mathematical modeling framework for next-generation sodium-ion batteries, in close collaboration with the experimental group of P. Adelhelm. We aim to elucidate the complex and hysteretic cell voltage behavior of promising sodium anode materials and thereby establish a rigorous thermodynamic basis for their interpretation. We will employ optimal control strategies for the current to infer the sodium chemical potential, which is encoded in the hysteretic cell voltage.
