Research Interests
Our group focuses on the development of advanced materials for energy storage and energy conversion, with an emphasis on understanding the structure–property relationships that govern electrochemical and thermochemical reaction mechanisms.
A major focus of our research is the development of solid-state materials for high energy density rechargeable batteries. We investigate electrode and solid electrolyte materials for next-generation energy storage systems, including Na-ion, Mg-ion, and all-solid-state batteries. Our work involves the synthesis of electrode and electrolyte materials, fabrication of batteries, and the correlation of redox mechanisms with structural changes during battery operation. We are also interested in developing sustainable strategies for recycling and repurposing battery wastes to support a circular economy.
Another important area of our research is clean H2 production through thermochemical H2O splitting. We develop solid-state materials that enable H2O splitting at lower temperatures, making the process more energy efficient. This research is fundamentally similar to the solar thermochemical H2 production, where renewable solar energy is used to split H2O and generate clean H2 as a fuel.
