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 ( $4.5 \times 1 0^{- 4}$ 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

Parameter	Value
Crystal Structure	NASICON (R-3c space group)
Density	95% theoretical density

Electrochemical Window	0–5 V vs. Li⁺/Li
Thermal Stability	No decomposition below 530°C

Performance Highlights

Interface Engineering
- Forms stable SEI with Li metal (critical current density: 1 mA/cm²).
- Low interfacial resistance (40 Ω·cm² in symmetric cells).
Mechanical Robustness
- Hardness: 9.2 GPa (700°C sintered).
- Puncture resistance: 446 gf (200 μm thickness).
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.
