Next-generation rechargeable batteries
Green world: To compete with currently commercialized Li-ion batteries, various types of batteries, including Na-ion, K-ion, multivalent-ion, and solid-state batteries, are investigated. Our group works on the development of new electrode and electrolyte materials for the next-generation rechargeable batteries based on the understanding of (i) structure-property correlation and (ii) synthesis science.

Synthesis science
Synthesis by design: In many cases, it is difficult to synthesize new materials, which are predicted to have good properties because we do not clearly understand materials synthesis mechanism even in the conventional solid-state method. Our group is interested in understanding of synthesis reaction mechanisms that can explain how the synthesis conditions (i.e., precursors, heating temperature, heating rate, cooling rate, etc.) control the formation of products. It will guide how to design synthesis routes to produce new (predicted) materials.

Autonomous Lab.
Future of the lab: Fast experiment iterations by autonomous laboratory will speed up materials discovery. We are developing AI-driven autonomous laboratory that can design, conduct (both synthesis and characterization) experiments, analyze experiment data, and guide the next experiment iteration without human intervention.
