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)

Material Advantages​​

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

Handling Protocol​​

  1. ​​Storage​​
    • Maintain in argon glovebox (O₂/H₂O <0.1 ppm)
    • 1-year shelf life in original packaging
  2. ​​Processing​​
    • Cold press at 300-400 MPa for pellet formation
    • Avoid water/oxygen exposure during cell assembly
  3. ​​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​​
