Solid State Electrolyte Lithium Aluminum Germanium Phosphate LAGP Powder Li1.5Al0.5Ge1.5PO43 NASICON Material

Product Overview

This high-purity solid-state electrolyte material is an advanced oxide-based inorganic conductor formulated as Lithium Aluminum Germanium Phosphate, Li1.5Al0.5Ge1.5(PO4)3 (LAGP). Recognized for its robust NASICON-type framework, this ceramic powder delivers superior lithium-ion mobility alongside outstanding air and chemical stability, serving as a core foundation for high-performance energy storage solutions.

Engineered specifically for next-generation solid-state lithium battery architectures, the material excels in thin-film separator fabrication, solid composite membranes, and cathode surface passivation. It provides research laboratories and industrial manufacturing teams with a reliable oxide electrolyte that eliminates the severe safety and handling hazards associated with volatile organic liquid electrolytes and moisture-sensitive sulfide systems.

Synthesized under stringent quality control protocols, this material exhibits exceptional phase purity, uniform stoichiometry, and strictly limited trace impurity levels. Its high electrochemical window and mechanical rigidity allow it to withstand demanding processing cycles, ensuring consistent sintering behavior, optimized grain boundary resistance, and reliable long-term battery performance under rigorous operating conditions.

Key Features

• Pure NASICON Crystal Phase: Fully indexed to standard PDF# 80-1923 via X-ray diffraction, ensuring a well-ordered 3D crystal lattice that optimizes lithium-ion conduction pathways and minimizes resistive secondary phases.
• High Room-Temperature Ionic Conductivity: Achieves an ambient ionic conductivity of approximately 3×10⁻⁴ to 6×10⁻⁴ S/cm, enabling rapid ion transport and lower internal cell impedance in solid-state cell designs.
• Ultra-High Chemical Purity (3N5 / ≥99.95%): Produced to a minimum purity of 99.95 wt%, preventing unwanted electrochemical side reactions and maintaining chemical integrity across extensive thermal processing cycles.
• Controlled Fine Particle Size (≤2 µm): Features a tight primary particle size distribution of 2 microns or smaller, facilitating dense powder packing, uniform slurry formulation, and lower sintering temperatures.
• Precise Stoichiometry Control: Maintains a fixed molar element ratio of Li:Al:Ge:P:O at 1.5:0.5:1.5:3:12, maximizing lattice stability and mechanical strength while maintaining optimal lithium carrier concentration.
• Strictly Regulated Metallic Impurities: Stringent purification limits critical transition metal and alkali impurities (Fe ≤28 ppm, Na ≤26 ppm, Si ≤25 ppm, Mg ≤20 ppm, Zr ≤18 ppm, Ca ≤17 ppm, Cu ≤16 ppm, K ≤15 ppm, Ba ≤15 ppm, Ni ≤10 ppm) to prevent internal micro-short circuits.
• Superior Ambient Processing Stability: Exhibits excellent environmental tolerance compared to moisture-reactive sulfide electrolytes, permitting safer and more flexible handling within standard dry-room or inert glovebox environments.
• Broad Electrochemical Stability Window: Demonstrates high anodic oxidation resistance, allowing safe operation against high-voltage cathode materials without premature electrolyte decomposition.
