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

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.

Key Specifications​​

EIS data obtained under 300MPa pressure (10mm diameter pellets)

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
