Tailoring the disorder landscape to increase conductivity in thiophosphate electrolytes

In a recent study published in Angewandte Chemie, Li and colleagues report that introducing disorder into Li5.5PS4.5ClxBr1.5-x solid electrolytes via Cl-/Br-/S2- mixing affects charge transport, leading to a room temperature ionic conductivity beyond 20 mS/cm. This entails the possibility of improving ion mobility by tailoring the occupational disorder in lithium argyrodites.
