Abstract
Li metal have been attracting attention as the next generation anode material for all-solid-state batteries (ASSBs) with high energy density. However, since severe side reactions occur at the interface between Li metal anode and solid electrolytes, Li metal anodes have not yet been commercialized. In this study, the authors examined the side reactions at the interface between the Li metal anode and oxide solid electrolyte using surface analysis technique. As a result, it was found that some of the components of the solid electrolyte diffused to the Li metal anode side. It was clear that suppressing this diffusion is essential for stable battery operation.
