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​​

  1. ​​Air Stability​​
    • Unlike LLZO, LATP remains stable in ambient conditions (RH <60%)
    • No moisture-induced degradation during handling
  2. ​​Electrochemical Performance​​
    • 3D ion channels enable 500+ cycle life in ASSLBs
    • Compatible with LiFePO₄ cathodes (tested @0.1C)
  3. ​​Mechanical Reliability​​
    • Sintered ceramic structure (not powder compact)
    • Withstands 200MPa assembly pressure

Handling Protocol​​

  1. ​​Surface Preparation​​
    • Polish with 1μm alumina slurry to remove Li₂CO₃ layer
    • Sputter gold electrodes (1-10Ω surface resistance)
  2. ​​Cell Assembly​​
    • Use CR2032 coin cells with molten Li anode
    • Apply gradual pressure (watch for shell deformation)
  3. ​​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)
