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

Layer	Material	Thickness	Function
Base Membrane	Polyethylene (PE)	7μm	Mechanical support
Coating Side A	Boehmite (AlOOH)	2μm	Thermal resistance
Coating Side B	LATP Solid Electrolyte	2μm	Ionic conduction
Surface Treatment	PVDF Adhesive	2μm/side	Electrode bonding

Key Performance Parameters

Parameter	Value	Test Method
Total Thickness	12.8 μm	Micrometer
Air Permeability	226 sec/100ml	ISO 5636-5
Puncture Strength	446 gf (Φ1.0mm)	ASTM D4833
Thermal Shrinkage (130°C)	MD:1.2%, TD:0.4%	Thermal aging test
Tensile Strength	MD:3099, TD:3053 Kgf/cm²	ASTM D882
Peel Strength	CCS:49 N/m, LATP:44 N/m	90° peel test

Material Advantages

Thermal Safety
- Boehmite coating provides 25% larger coverage than Al₂O₃ at equal mass
- Withstands 130°C with minimal shrinkage (<1.5%)
Electrochemical Performance
- LATP coating enhances Li⁺ transport (44 N/m bonding strength)
- PVDF layers enable >49 N/m electrode adhesion without blocking pores
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

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