| Outline of Final Research Achievements |
We developed solid-solid interfaces between metal Li (or Na) and a solid electrolyte. The Li3PS4 electrolyte was partially decomposed at the vicinity of the interface. The Li dissolution-precipitation behavior was improved by both inserting Au thin-film at the interface and increasing operating temperatures. All-solid-state cells with Na-Sb / Na3PS4 interfaces operated reversibly and the preparation procedure of Na3PS4 thin-films by the PLD method were determined.
