The Choi Group’s research is aimed at rational design and engineering of next generation electrochemical systems for human convenience and energy applications. We seek to address key questions related to the electrochemical systems by leveraging electrochemistry, materials chemistry, and device engineering. Our interests include (1) synthesis of new materials for electrochemical devices, (2) combining electroanalytical chemistry, spectroscopy, and synchrotron characterizations to understand thermodynamics and kinetics of charge transfer processes (electron, ions, redox species and/or charge carriers), (3) perturbating chemistry and physics of materials to develop structure-property relationships, and (4) developing architectures for efficient energy storage and conversion devices (e.g. battery, supercapacitors, and solar fuel production) and next generation electronics (e.g. sensors, electronic ion pumps, and neuromorphic computing).
