Lithium Phosphorus Sulfur Chloride LPSCI Sulfide Solid Electrolyte ≥6mS/cm All-solid-state Battery Material Research Experiment
Material Overview
LPSCI (Li₅.₅PSCl₁.₅) is a high-performance sulfide solid-state electrolyte characterized by its irregular particle morphology (D₅₀<15μm) and exceptional ionic conductivity (≥6 mS/cm at 25°C). The SU8600 SEM image (20.0kX magnification) reveals its distinctive rough-textured particles optimized for all-saolid-state battery research.

Performance Highlights
1. Ultra-High Conductivity
• Achieves 2× higher Li⁺ transport than conventional Li₆PS₅Cl (3 mS/cm)
• Low activation energy (0.20-0.25 eV) enables stable performance at -20°C
2. Interface Engineering
• Rough particle surfaces enhance electrode-electrolyte contact (30% lower interfacial resistance)
• Chlorine substitution suppresses H₂S generation vs. pure sulfide systems
3. Research Applications
• Prototyping of 400+ Wh/kg all-solid-state batteries
• Compatible with:
- Li-metal anodes (CCD >2 mA/cm²)
- High-voltage NCM811 cathodes (4.3V)
Microstructural Analysis
(Per SU8600 SEM at 20.0kX Magnification)
• Particle Distribution: Broad size range (2-35μm) ensures dense packing
• Surface Texture: Nano-scale roughness promotes electrolyte wetting
• Defect Characteristics: Minimal cracks/voids (<1% area fraction)
Handling Protocol
| Step | Requirement |
|---|---|
| Storage | Argon glovebox (<0.1ppm O₂/H₂O) |
| Processing | Cold-press at 300-400 MPa |
| Safety | H₂S detectors mandatory |
Note: Custom particle size fractions (e.g., <10μm) available for thin-film battery research.
