Product Description
Material Overview
LPSCI (Li₅.₅PSCl₁.₅) is a high-performance sulfide solid-state electrolyte featuring irregular particle morphology (D₅₀<15μm) and exceptional ionic conductivity of ≥6 mS/cm at 25°C. SEM imaging at 20.0kX magnification reveals distinctive rough-textured particles optimized for advanced all-solid-state battery research applications.
Key Specifications
| Property | Specification | Verification Method |
|---|---|---|

Performance Highlights
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
Interface Engineering
- Rough particle surfaces enhance electrode-electrolyte contact (30% lower interfacial resistance)
- Chlorine substitution suppresses H₂S generation compared to pure sulfide systems
Research Applications
- Prototyping of 400+ Wh/kg all-solid-state batteries
- Compatible with Li-metal anodes (CCD >2 mA/cm²)
- Compatible with high-voltage NCM811 cathodes (4.3V)
Microstructural Analysis
SU8600 SEM at 20.0kX Magnification reveals:
- 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 |
Custom particle size fractions (e.g., <10μm) available for thin-film battery research.
