Lithium Phosphorus Sulfur Chloride LPSCI Sulfide Solid Electrolyte Research Experiment

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-solid-state battery research.

​Key Specifications​​

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​​

​​Note​​: Custom particle size fractions (e.g., <10μm) available for thin-film battery research.
