We employ analytical and physical chemistry strategies to make renewable energy applications better
LITHIUM ION BATTERIES
Using an operando x-ray microscopy platform that maps the dynamics of the Li composition and insertion rate in battery particles, we discover electrochemical kinetic rules of Li-ion batteries.

MICROBIAL FUEL CELLS
Electrochemically active bacteria which converts chemical bonds to electricity (or converts electricity to chemical bonds) hold promise for the next generation fuel cell. We study charge transfer mechanism between bacteria and electrode.
90% of global energy is produced by combustion engine which operates at 30~40%. It means ~60% of energy is just lost to environment as waste heat. Solid-state thermoelectric device converts the waste heat to electricity and nanoscale materials can show extremely high efficiency. Our group is dedicated to discover the design rule of next generation thermoelectric materials.
