The research in the group of Electrochemical Engineering (EE) is focused on the fundamental engineering aspects of the electrochemical systems such as advanced batteries, electrolyzers, and fuel cells. The research philosophy of the group is to couple experiment and theory to provide in-depth insight into and develop electrochemical energy storage and conversion systems. The goal is to correlate the intrinsic materials’ properties, formulation, processing, and micro-structure of the electrode and electrolyte components to the performance and aging metrics of the operating system. Applications of this research include in-depth analysis of electrochemical performance, optimization of the electrode/electrolyte formulations, end-of-life tests/simulations, and development of physics-based models/algorithms for the device control and state-of-charge and state-of-health prediction purposes.
