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

• 3-5× higher conductivity than oxide electrolytes (LATP/LLZO)
• Low activation energy (0.2-0.3 eV) for Li⁺ migration

• Softer texture vs. LAGP enables cold pressing at 300MPa
• Forms intimate electrode-electrolyte interfaces

• Reproducible conductivity (1.68×10⁻³ S/cm) confirmed by independent testing
• Stable Nyquist plot characteristics (see EIS graph)

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

• Maintain in argon-filled glovebox (O₂/H₂O <0.1ppm)
• Use vacuum-sealed containers for transfer

• Cold press at ≥300MPa for pellet formation
• Sputter Au electrodes for EIS measurements

• Decomposes in moist air (H₂S generation risk)
• Requires dry-room processing equipment

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