Lab Description
We are mainly trying to design and discover advanced new energy materials by exploring including non-equilibrium thermodynamic chemical spaces. Based on the novel material synthesis, we systematically study on the material characterization and finally apply the material to the fabrication of electrochemical devices to bridge the fundamental discovery and knowledge to the energy storage and conversion technologies. We are focusing on the defining the key question with "What" and "How" and solving the core issues in energy research fields.
Research Theme1. Designing and exploring new materials for energy storage and conversion (Cathode & Solid-Electrolyte)2. Advanced X-ray characterization for probing interfacial phenomena3. Fabrication and Characterization of Solid-State Battery4. New system of energy storage and conversion: Fluoride ion battery
