Product Description
LATP Solid State Battery Separator GMSS02
Product Overview
The GMSS02 separator by Canrd Xwell is a multi-layer composite membrane engineered for high-performance semi-solid lithium batteries. This advanced separator features a 7μm polyethylene base with dual functional coatings (2μm boehmite + 2μm LATP) and PVDF adhesive layers, delivering superior thermal stability, excellent electrode adhesion, and maintained 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
✓ Suitable for coin cells & pouch cells
✓ High-temperature systems (≤130°C)
✖ Not suitable for pure solid-state batteries
✖ Not compatible with 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
