In this research, we aim to create an all-solid-state sodium ion battery (NaB) using crystallized glass. In the development of oxide-based all-solid-state batteries, the process of creating a low-resistance Na ion conductive interface between the active material and the solid electrolyte is very important.Therefore, in this research, we proposed and demonstrated a new process that contributes to the creation of an oxide-based all-solid-state sodium-ion battery that integrates an active material and a solid electrolyte using local heating by laser irradiation.
