Research Interests
Research Areas
We uncover nanoscale phenomena in energy materials and translate fundamental discoveries into practical technologies.
Next-Generation Battery Materials
Developing advanced battery systems — including lithium metal and all-solid-state batteries — tailored to the energy demands of EVs, energy storage systems (ESS), and urban air mobility (UAM).
Reaction Mechanisms & Degradation Modes
Elucidating the fundamental principles governing electrochemical reactions, electrode processing, and failure modes in battery systems to enable rational design and long-term reliability.
Electrode–Electrolyte Interface Engineering
Understanding the formation principles of electrode–electrolyte interfaces (SEI/CEI) at the atomic scale, and applying this knowledge to engineer high-performance electrolytes and interphase layers.
Advanced Characterization Platform
Developing cutting-edge TEM-based analytical techniques — including in situ, cryo, and 4D-STEM — combined with AI-based data processing to push the boundaries of nanoscale characterization.
