Efficient energy storage and conversion technologies are essential to realize a sustainable society. From the viewpoint of materials science, our laboratory is conducting research and development of innovative rechargeable batteries and highly efficient electrochemical processes. Our goal is to contribute to the realization of a truly affluent society and to knowledge by exploring the essence behind phenomena.



Our laboratory was established at Institute of Industrial Science, The University of Tokyo in April 2016. The achievements of our research are published in the form of academic papers, books, and patents etc.




We continue to take on challenges as a team with the strengths of each member. We look forward to the day when we can research and grow with you.


An academic paper on oxide-based solid electrolytes by our student, DingYuan Huang et al. has been accepted for publication in EcoEnergy.

Ga-doped Li7La3Zr2O12 was used as an oxide-based solid electrolyte to investigate in detail how the synthesis conditions and particle size affect the electrochemical and chemical stability of the solid electrolyte.

Mr. Aisaku Oda, M2 student in our laboratory, will participate in TOKYO STARTUP GATEWAY 2023 THE FINAL on Sunday, November 26, 2023.

An academic paper by our student Mr. Wang Wencong et al. on oxygen reduction catalysts has been accepted for publication in The Journal of Physical Chemistry C.

The effects of crystal structure, metal valence state, and cationic vacancy concentration on ORR catalytic activity were investigated by replacing Mn ions with Co ions in the perovskite-type oxide (LaMn)1-xO3 with cation vacancies. The results showed that the Co substitution shortens the Mn-O interatomic distance and increases the activity, but at the same time lowers the concentration of Mn ions, indicating that there is an appropriate amount of Co substitution that maximizes the activity. Furthermore, the application to Zn-air batteries was also made.

Wiley presented Assoc. Prof. Yagi with a certificate of recognition for his contribution to peer review in 2022 (Advanced Materials, Advanced Energy Materials, Advanced Functional Materials, Small).

The 16th Workshop on Reactive Metal Processing (RMW16) was held at MIT, USA.

Researchers at the forefront of the resources and energy field gathered from around the world for a lively discussion at MIT, USA, on March 24-25, 2023. Assoc. Prof. Yagi gave an oral presentation and our M1 student Mr. Oda gave a poster presentation.
