Sulfide LGPS Lithium Germanium Phosphorus Sulfur Solid Electrolyte (20um) Li10GeP2S12 Battery Assembly Material

Product Overview

Li₁₀GeP₂S₁₂ (LGPS) is a high-performance sulfide solid-state electrolyte with exceptional ionic conductivity (7±1 mS/cm at 25°C). This grayish-brown powder (10-20μm particle size) features a unique tetrahedral-octahedral framework enabling isotropic lithium-ion diffusion, making it ideal for advanced all-solid-state battery research.

Key Specifications

Parameter	Specification
Chemical Formula	Li₁₀GeP₂S₁₂
Particle Size	10-20 μm (D₅₀)
Ionic Conductivity	7±1 mS/cm (25°C)
Appearance	Grayish-brown powder
Packaging	Glass bottle + vacuum-sealed Al bag

Material Advantages

Superior Ion Transport
- 3D diffusion channels enable near-liquid conductivity
- Low activation energy (0.2-0.3 eV) for stable low-temperature performance
Electrochemical Stability
- Compatible with Li-metal anodes (>2 mA/cm² CCD)
- Minimal interfacial resistance with NCM/LCO cathodes
Structural Characteristics
- Tetrahedral (PS₄)³⁻ and octahedral (GeS₄)⁴⁻ coordination
- Isotropic Li⁺ migration pathways

Handling Protocol

Storage
- Maintain in argon glovebox (O₂/H₂O <0.1 ppm)
- 1-year shelf life in original packaging
Processing
- Cold press at 300-400 MPa for pellet formation
- Avoid water/oxygen exposure during cell assembly
Safety
- H₂S generation risk if hydrated - use fume hoods

Applications

All-solid-state Li batteries (400+ Wh/kg prototypes)
Hybrid electrolyte systems
High-energy-density cell research

Note: Germanium scarcity impacts cost; alternatives available upon request.

Manufactured by Kelude with ISO-certified quality control.
