Motivation and Outline

To realize carbon neutral society, dramatic advancement in energy storage technologies is highly urged for.

We, Functional Electrolyte Synthesis (FES) team, are working on the development of functional electrolyte materials and artificial interface to achieve breakthrough toward materialization of next generation energy storage technologies. Based on the fundamental understanding of electro-, solution, and structural chemistry, the target materials will be realized by combining various synthetic methodologies including organic, inorganic, and nano scientific techniques.

Based on a fundamental understanding of electrochemistry, solution chemistry, and structural chemistry, this diagram combines various synthetic methods, including organic, inorganic, and nanoscience, to achieve the desired material.

Facilities

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.

Research Results

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.

Selected Recent Results

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.
