Description

We explore fundamental phenomenon governing battery performance across technical readiness levels. A couple of areas where postdoctoral support is required follow. 1. Diagnose complex discharge mechanisms of emerging batteries chemistries like ambient Na-S and anode-free Li-ion using unique characterization and instrumentation including: in-situ optical microscopy, in-situ spectroscopy, in-operando EXAFS, and ex-situ micro-CT and SEM. 2. Investigate the interplay of thermal and electrochemical energy. Battery charging and discharging produces heat and these behaviors are dependent on ambient environment. Build custom instrumented pouch cells and utilize novel isothermal battery calorimetry and accelerating rate calorimetry measurements.
