Anomalous superionic conductivity in van der Waals lithium thiophosphates triggered by interlayer molecules

Layered LiInP 2 S 6 can trigger an anomalous superionic conductivity of 5.3 × 10 −3 S cm −1 in a solid hydrated phase by interlayer molecules uptake, which is enhanced by more than four orders of magnitude compared to that in an anhydrous phase.
