Frontier Battery Materials Group

Group Website

We are re-launched as Frontier Battery Materials Group.

To achieve the 2050 carbon neutrality goal, advancing the performance of energy storage devices is an urgent priority. Rechargeable batteries based on ubiquitous elements such as magnesium and calcium as core materials are expected to have low geopolitical risks and, by leveraging multi-electron reactions, are anticipated to enable high-capacity storage.

The Frontier Battery Materials Group focuses on such multivalent metal batteries, and is engaged in the design and development of electrodes, electrolytes, and their interfaces. By delaminating battery characteristics into their constituent elements from the perspectives of solution chemistry, structural chemistry, and solid-state chemistry, we establish design principles and realize promising materials for high-performant battery applications using organic, inorganic, and nanomaterial synthesis technologies.

Owing to the research interests, a wide spectrum of synthetic and analytical equipment is at hand in our lab. Schlenk-line, dry chamber, and one of the glove-boxes are available for organic synthesis,while inorganic materials can be synthesized using tube furnace and autoclave. Physicochemical and electrochemical characteristics of the developed materials will be evaluated by analytical techniques.

Toward the realization of innovative batteries with multivalent metal negative electrodes, we are working to develop high-performant electrolytes and interface regulation technologies based on a deeper academic understanding of interfacial phenomena.

• An electrolyte material with remarkable Mg plating/stripping performance was successfully developed via solvation sheath regulation via multidentate oligoether ligand integration.

• We revealed the failure mechanism of rechargeable magnesium batteries at elevated temperature.
