Next–Generation Battery Technologies
We are developing next–generation batteries that surpass the energy density of
conventional lithium–ion batteries. Among these, lithium–sulfur (Li–S) batteries
are particularly promising due to their lightweight nature and high theoretical energy
density. By using sulfur as the cathode material, Li–S batteries can achieve
significantly higher performance compared to existing technologies. However, their
practical use is limited due to issues such as sulfur dissolution in the electrolyte and
complex electrochemical reactions that shorten battery lifespan. To address these
challenges, we are conducting research in the following areas:
•    Development of various carbon materials
•    Synthesis of composite materials integrating semiconductor processing techniques
•    Design of electrochemical catalysts to enhance charge and discharge efficiency
Additionally, we are actively researching solid–state batteries, which provide
superior safety and energy density. Our focus is on developing stable interfacial
reactions to enhance overall battery performance and ensure long–term reliability.

Electrochemical Catalysis for Clean Energy
Our research is also dedicated to developing advanced electrochemical catalysts that
enable efficient energy conversion and contribute to reducing greenhouse gas
emissions. By controlling catalyst properties at the nanoscale, we aim to enhance
efficiency, selectivity, and stability in various catalytic reactions. To achieve these
goals, we are working in the following areas:
•    Development of single–atom catalysts (SACs)
•    Design of nanostructured electrochemical catalysts to accelerate reaction
      kinetics
•    Research on electrochemical transformations, including hydrogen production
      through water splitting reactions (HER & OER) and CO₂ conversion into
      valuable fuels and chemicals
