Li6PS5Cl LPSCl Lithium-ion Battery Solid Electrolyte Powder 1-5um For Scientific Research

Product Overview​​

Li₆PS₅Cl (LPSCl) is a high-performance sulfide solid electrolyte powder with particle sizes of 1-5μm, offering exceptional room-temperature ionic conductivity (~10⁻³ S/cm). This argyrodite-type material enables advanced research in all-solid-state lithium batteries (ASSLBs) while requiring careful air-sensitive handling.

Material Advantages​​

  1. ​​Superior Ionic Transport​​
    • 3-5× higher conductivity than oxide electrolytes (LATP/LLZO)
    • Low activation energy (0.2-0.3 eV) for Li⁺ migration
  2. ​​Mechanical Properties​​
    • Softer texture vs. LAGP (enables cold pressing at 300MPa)
    • Forms intimate electrode-electrolyte interfaces
  3. ​​Third-Party Verified Performance​​
    • Reproducible conductivity (1.68×10⁻³ S/cm) confirmed by independent testing
    • Stable Nyquist plot characteristics (see EIS graph)

Technical Validation​​

​​Electrochemical Impedance Spectroscopy (EIS):​​

  • Test condition: 300MPa pressed pellet (10mm diameter, 0.79cm² area)
  • Characteristic impedance: 127 Ω
  • Calculated conductivity: 1.68×10⁻³ S/cm

Handling Protocol​​

  1. ​​Storage​​
    • Maintain in argon-filled glovebox (O₂/H₂O <0.1ppm)
    • Use vacuum-sealed containers for transfer
  2. ​​Processing​​
    • Cold press at ≥300MPa for pellet formation
    • Sputter Au electrodes for EIS measurements
  3. ​​Safety​​
    • Decomposes in moist air (H₂S generation risk)
    • Requires dry-room processing equipment

Applications​​

  • All-solid-state lithium battery prototyping
  • Hybrid solid-liquid electrolyte systems
  • Interface engineering research
