Abstract
<p>High voltage operation for achieving high energy density is a next research direction of all-solid-state batteries with sulfide solid-electrolytes. In this study, we fabricated film-batteries consisted of layered rocksalt type cathode and sulfide solid electrolyte to elucidate interfacial phenomena at high voltage regions. Depth-resolved X-ray photoemission spectroscopy and in situ X-ray diffraction clarified the structural changes at the model interfaces. We will discuss a crucial factor that determines the rate-determining step and reversible charge-discharge reaction during high voltage battery operation.</p>
