Energy Storage Materials Engineering Lab
Research
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.
Publications
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.
People
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.
News
A scientific paper on positive electrode active materials for magnesium rechargeable batteries by our former student, Project Researcher, Mr. Isaac Oda-Bayliss, et al. has been accepted for publication in J. Mater. Chem. A.
We have revealed that V-ion doping of α-K<sub><i>x</i></sub>MnO<sub>2</sub>, a positive electrode active material for magnesium rechargeable batteries, has effects of lowering overpotential, improving reactivity, and stabilizing active materials. This result was achieved in collaboration with Prof. Ichitsubo of Tohoku University and Prof. Kobayashi of Hokkaido University.
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.
