LATP Lithium Aluminum Titanium Phosphate Solid Electrolyte Sheet Battery Material Li1.3Al0.3Ti1.7 (PO4) Can Be Customized
Product Overview
Xwell's LATP (Lithium Aluminum Titanium Phosphate) solid-state electrolyte sheets are high-performance ceramic membranes for all-solid-state lithium batteries. With NASICON-type crystal structure and air stability, these white ceramic sheets (13±0.1mm diameter) enable safe and efficient ion transport (0.7 mS/cm at 25°C) without requiring glovebox handling.

Material Advantages
-
Air Stability
- Unlike LLZO, LATP remains stable in ambient conditions (RH <60%)
- No moisture-induced degradation during handling
-
Electrochemical Performance
- 3D ion channels enable 500+ cycle life in ASSLBs
- Compatible with LiFePO₄ cathodes (tested @0.1C)
-
Mechanical Reliability
- Sintered ceramic structure (not powder compact)
- Withstands 200MPa assembly pressure
Handling Protocol
-
Surface Preparation
- Polish with 1μm alumina slurry to remove Li₂CO₃ layer
- Sputter gold electrodes (1-10Ω surface resistance)
-
Cell Assembly
- Use CR2032 coin cells with molten Li anode
- Apply gradual pressure (watch for shell deformation)
-
Testing
- EIS measurement range: 1MHz-0.1Hz
- Thermal aging test @100°C recommended
Applications
- All-Solid-State Batteries (Li-metal compatible with interface modification)
- Hybrid Electrolyte Systems (LATP+PEO composites)
- Coating Research (Separator/electrode surface modification)
Storage: Dry environment (desiccator recommended)
