Improved Air Stability of Li Argyrodites Through PS43− Rotation Suppression by Al and Se Co‐Substitution for All‐Solid‐State Batteries

Advanced Science, EarlyView.
Al/Se co‐substitution in Li6PS5Cl achieves enhanced dry‐air stability and improves Li+ conductivity, retaining 85% of its high Li+ conductivity (4.91 mS cm−1 at 30 °C) after dry‐air exposure (dew point −40 °C for 5 h). The stability enhancement is experimentally validated and underpinned by theoretical analyses indicating suppressed rotation of P[S2SeO]
