LAGP Lithium Aluminum Germanium Phosphate Solid State Electrolyte Sheet Li1.5Al0.5Ge1.5P3O12

LAGP Lithium Aluminum Germanium Phosphate Solid State Electrolyte Sheet Battery Test Material Li1.5Al0.5Ge1.5P3O12

​Material Overview​​

LAGP (Li₁.₅Al₀.₅Ge₁.₅(PO₄)₃) is a NASICON-structured oxide solid electrolyte renowned for its high ionic conductivity ($4.5\times 10^{-4}$ S/cm at 25°C) and exceptional air/water stability. As a critical component for solid-state lithium batteries, LAGP pellets enable dendrite suppression and thermal safety (stable up to 350°C).

​​Key Properties​​

​​Performance Highlights​​

1. ​​Interface Engineering​​

   • Forms stable SEI with Li metal (critical current density: 1 mA/cm²).
   • Low interfacial resistance (40 Ω·cm² in symmetric cells).

2. ​​Mechanical Robustness​​

   • Hardness: 9.2 GPa (700°C sintered).
   • Puncture resistance: 446 gf (200 μm thickness).

3. ​​Battery Integration​​

   • Compatible with LiFePO₄ cathodes (142 mAh/g at 0.1C).
   • Stable cycling >500 hours (Li/LAGP/Li symmetric cells).

​​Applications​​

• ​​Solid-State Lithium Batteries​​ (ASSLBs).
• ​​Lithium-Air/Lithium-Water Batteries​​.
• ​​Hybrid Solid-Liquid Electrolyte Systems​​

​​Handling Notes​​

• ​​Storage​​: Dry environment (RH <30%) to prevent moisture absorption.
• ​​Processing​​: Compatible with dry-room assembly; avoid >60°C pre-treatment.
