Lithium Thiophosphate Chloride Li6PS5Cl Lithium Phosphorus Sulfide Chloride

Lithium thiophosphate chloride (Li6PS5Cl) is a sulfide-based solid electrolyte belonging to the argyrodite family, renowned for its high ionic conductivity (>1 mS/cm at 25°C), wide electrochemical stability window (0–5 V vs. Li/Li⁺), and compatibility with lithium metal anodes. It is a cornerstone material for next-generation all-solid-state batteries (ASSBs), offering enhanced safety and energy density compared to traditional liquid electrolytes.

  • High Ionic Conductivity: Reaches >3 mS/cm at 25 °C, enabling fast lithium - ion movement for quick charging and high - power batteries.
  • Wide Electrochemical Window: Stable from 0 - 7 V vs. lithium, compatible with various high - voltage cathodes for higher energy density.
  • Good Processability: Comes as a powder, easily cold - pressed or combined with other materials for battery membrane fabrication.
  • Thermal Stability: Contributes to overall battery thermal stability, raising the thermal runaway onset temperature.
