Beschreibungen/Notizen

• A Na‐ion solid‐state electrolyte, Na3P0.62As0.38S4, is developed with an exceptionally high conductivity of 1.46 mS cm–1 at 25 °C and enhanced moisture stability. Dual effects of alloying element As (lattice expansion and a weaker AsS bond strength) are responsible for the superior conductivity. Improved moisture stability is regulated by shifting low‐energy moisture reactions to high‐energy ones due to As.
