About this position
Postdoctoral Researcher in Solid-State Batteries and Oxide Solid Electrolytes at the National Institute for Materials Science (NIMS), Tsukuba, Ibaraki, Japan.
The position is in the Energy and Environmental Materials Research Center, specifically the Solid State Battery Ionics Group / Solid State Battery Materials Group. The project focuses on all-solid-state batteries using oxide-based solid electrolytes, with research on lithium- and sodium-based systems, ion conduction phenomena, and materials/process development to improve area scale-up, lifetime, and input/output characteristics.
Research activities include experimental work such as material synthesis, electrochemical measurements, and spectroscopy/structural analysis. The post is well suited to candidates interested in nanotechnology and materials science, inorganic materials chemistry, energy chemistry, and composite materials/interfaces.
This is a fixed-term postdoctoral-equivalent role. The salary is approximately ¥5 million per year or more, with a monthly salary starting at ¥448,816 depending on experience and ability, including deemed overtime pay. Commuting allowance is available under the organization’s rules, and standard social insurance coverage is provided.
Eligibility requires a doctoral degree, or expected completion by the time of appointment. Japanese communication ability with related organizations is considered an advantage. The planned start date is as soon as possible after November 2026.
Applications are accepted from 2026-10-05 to 2026-12-31, though the recruitment may close early once a suitable candidate is found. Apply by preparing the required documents, compiling them into a ZIP file, and uploading them through the designated NIMS application page.
