Lithium Aluminum Germanium Phosphate Material

Overview 

LAGP (Lithium Aluminium Germanium Phosphate) is a high-performance NASICON-type solid electrolyte widely used in solid-state lithium battery research. With the chemical composition Li₁.₅Al₀.₅Ge₁.₅(PO₄)₃, this material exhibits fast lithium-ion conduction through a rigid three-dimensional phosphate framework, enabling efficient ion transport while maintaining excellent mechanical and thermal stability.

The NASICON crystal structure provides interconnected lithium-ion migration pathways, allowing LAGP to function as a stable ion-conducting separator between electrodes without the safety risks associated with liquid electrolytes.

Key Material Characteristics

• Crystal Structure: NASICON-type framework
• Appearance: High-purity white powder
• Ion Conduction: Predominantly Li⁺ transport
• Impurity Control: Trace metallic impurities controlled at low ppm levels
• Thermal Stability: Suitable for elevated-temperature electrochemical studies

The controlled impurity profile ensures reproducible electrochemical behaviour, making this material well suited for fundamental research and prototype development.

Compatibility and Integration

LAGP solid electrolyte powder is compatible with:

• Lithium metal and lithium alloy electrodes
• Composite cathodes and interlayers
• Coin cells, pelletised solid-state cells, and custom electrochemical cells

It can be readily integrated into experiments using potentiostats, battery cyclers, and electrochemical impedance spectroscopy (EIS) systems supplied by ScienceGears.

Typical Applications

• Solid-state lithium battery research
• Interface studies between solid electrolytes and electrodes
• Ionic conductivity and impedance analysis
• All-solid-state cell prototyping
• Academic and industrial energy storage research
