PI message

The control and mechanistic understanding of charge transfer reactions at the electrified interfaces and electronic and ionic migrations in thin film materials are crucial for developing novel electrochemical devices and functional surfaces. At Interfacial Electrochemistry Laboratory, we are trying to control the interfaces for fabricating novel materials and devices for efficient electrochemical energy conversion and designing nanostructured surfaces with various functionalities.

Research

In the Laboratory of Interface Electrochemistry, we conduct research to solve environmental, energy, and resource problems based on the study of electrochemistry. Electrochemistry is applied to a wide range of fields in society, including anticorrosion coatings, batteries (fuel cells, solar cells, and next-generation secondary batteries), and electrolysis, and we work on research leading to various applications. In the anticorrosion coatings, we create a surface that repels water and oil stains by fabricating a microstructure on the metal surface using an electrochemical technique, i.e., anodization. In the batteries, we synthesize ceramic conductor materials that efficiently conduct protons, hydrides, and oxygen, and develop highly efficient fuel cells. We also synthesize nanomaterials such as nanosheets and nanoparticles designed from the aspects of nano and atomic arrangement, which are applied water electrolysis for highly efficient H2 gas production.
