Work Description
We conduct research on solid-state batteries utilizing oxide-based solid electrolytes. Focusing on lithium and sodium-based solid-state batteries, we aim to realize oxide-based solid-state batteries through material and process development targeting ion conduction phenomena within the battery, large-area implementation, extended lifespan, and improved input/output characteristics. The work will primarily involve experimental approaches, such as electrochemical measurements, spectroscopic analysis, and structural characterization, to enhance the performance of oxide-based solid-state batteries. We welcome candidates with a strong interest in solid-state batteries and solid electrolyte materials, who are highly motivated to engage in experimental research involving material synthesis, electrochemical characterization, and structural analysis.
