Fig. 1: Schematic illustration of the protection strategy for Li6PS5Cl (LPSC) in humid ambient air.

While LPSC undergoes hydrolysis and suffers a ~ 4 orders of magnitude reduction in ionic conductivity, a liquid coating of 1-undecanethiol (UDSH) with some of it chemically adsorbed onto the LPSC surface protects the material, which loses less than 10-fold in conductivity in 33% relative humidity (RH). UDSH forms a hydrophobic shield around the LPSC particles.
