LATP Solid Electrolyte Coating Isolation Film GMSS02 Double-sided Single Coating B/L2+2+7+1+2 Lithium Liquid Battery

​Product Overview​​

The GMSS02 separator by Canrd Xwell is a multi-layer composite membrane designed for high-performance semi-solid lithium batteries. Combining a 7μm PE base with dual functional coatings (2μm boehmite + 2μm LATP) and PVDF adhesive layers, this white, smooth film enables superior thermal stability and electrode adhesion while maintaining ionic conductivity.

Structural Composition​​

Key Performance Parameters​​

Material Advantages​​

1. ​​Thermal Safety​​

   • Boehmite coating provides 25% larger coverage than Al₂O₃ at equal mass
   • Withstands 130°C with minimal shrinkage (<1.5%)

2. ​​Electrochemical Performance​​

   • LATP coating enhances Li⁺ transport (44 N/m bonding strength)
   • PVDF layers enable >49 N/m electrode adhesion without blocking pores

3. ​​Mechanical Reliability​​

   • High puncture resistance (446gf) prevents dendrite penetration
   • Balanced MD/TD elongation (112%) for winding compatibility

Applications & Limitations​​

✓ ​​Ideal for​​:

• Semi-solid lithium batteries
• Coin cells & pouch cells
• High-temperature systems (≤130°C)

✖ ​​Not suitable for​​:

• Pure solid-state batteries
• Sodium-ion batteries

Handling Protocol​​

1. ​​Storage​​: Keep sealed in dry environment (RH<30%)
2. ​​Processing​​: Use in dry rooms; avoid >60°C exposure before cell assembly
3. ​​Lifetime​​: 6 months in original vacuum packaging
