Research Overview:
The Solid-State Battery Ionics Group aims to develop long-lasting and safe solid-state batteries to contribute to the realization of a carbon-neutral society. To this end, we are working to elucidate the mechanisms of ion transport within solid-state battery materials and at their interfaces, and to establish design guidelines based on fundamental scientific principles. Furthermore, by leveraging advanced experimental techniques such as NMR, TOF-SIMS, and operando analyses, we visualize ion dynamics and promote the development of next-generation solid-state battery materials.

Student Recruitment:
We are seeking applicants for the doctoral program in the Hokkaido University–NIMS Joint Graduate School. Students are eligible for financial support through the NIMS Junior Researcher Program. We also welcome applications from working professionals pursuing a PhD.
