The goal of our laboratory is to design functional nano/micro-sized energy materials for advanced energy storage and conversion applications. Specifically, our research activities are currently focused on developing 'Next-generation Batteries‘, targeting applications in large-scale devices such as electrical vehicles (EVs) and energy storage systems (ESSs). By rationally designing and characterizing various electrode materials, we aim to deeply research on the future battery systems such low-cost Multivalent ion battery, safe All-solid-state battery, high-energy Metal-air battery, and high-performance Advanced functional material We believe that the development of efficient energy storage material is a key technological challenge of the 21st century, which will ultimately guide to achieve the carbon-neutral energy cycle.
