Masahiro Tatsumisago, Former OMU President and current Executive Advisor at Osaka Metropolitan University, has been selected for the NIMS Award 2026 from the National Institute for Materials Science (NIMS).
The NIMS Award is an annual international award for individual researchers and groups within the field of materials science. Selection for the award is based on a theme, recommendation, and committee assessment. Under this year’s theme, “Energy Storage Materials,” Tatsumisago, together with Professor Ryoji Kanno from the Institute of Science Tokyo, was chosen for his contributions to world-changing applications in all-solid-state batteries. The ceremony and recipients’ lectures for the NIMS Award 2026 will take place during the “NIMS Award Symposium 2026 - Engineering the Future of Solid State Batteries” to be held on Tuesday, November 10 at the Tsukuba International Congress Center.
Overview
Through the creation of ion-conductive glasses and glass-ceramic materials typified by the Li₂S–P₂S₅ system, Tatsumisago’s research pioneered amorphous and metastable crystalline materials exhibiting high ionic conductivity, which has laid the materials foundation for the practical application of sulfide-based solid electrolytes. This work has established a unified design principle for high ionic conductivity using a broad range of materials and a foundation for the practical application of all-solid-state batteries.
Message from Masahiro Tatsumisago
"I am both surprised and deeply honored to have received the prestigious NIMS Award. This recognition comes from the high evaluation of over 40 years of research in my laboratory on the development of glass-based solid electrolytes and their application to all-solid-state batteries. With great enjoyment, enthusiasm and determination, I have been able to pursue this research thanks to the guidance of the senior professors who led me into the field, as well as the support of my collaborators in Japan and abroad, my colleagues, laboratory staff, and all my former and current students. I would like to express my heartfelt gratitude to all of them."
