What is the thermal shrinkage resistance of the Alumina PVDF Coated Battery Separator with a 17 μm PE base?
The Al2O3 ceramic and PVDF coating on this separator improves thermal-shrinkage resistance, which is critical for battery safety at elevated temperatures. The PE base has a melting point of approximately 140 °C, and the coating helps maintain dimensional stability. However, the product description does not specify a quantitative thermal shrinkage percentage, so the improvement is qualitative.
How does the double-side single coating configuration affect the separator's bonding to the positive electrode?
The double-side single coating configuration applies a 2 μm CCS alumina ceramic layer on one side and a 2 μm PCS PVDF layer on the opposite side. The PVDF side is designed to bond the positive-electrode sheet to the separator, enhancing cell integrity. The ceramic side provides thermal resistance and mechanical strength, as indicated by a puncture strength of 526 g and a tensile strength of 1533/1282 kgf/cm² (MD/TD).
What are the key mechanical and physical properties of this 17 μm PE separator that affect battery manufacturing?
This separator has a product thickness of 17.0 μm, an air permeability of 217.8 sec/100 ml, and a porosity of 40%. Its mechanical properties include a puncture strength of 526 g, tensile strength of 1533/1282 kgf/cm² (MD/TD), and elongation at break of 0.7%/0.6% (MD/TD). These parameters influence winding tension, electrolyte wetting, and resistance to dendrite penetration during cell assembly and cycling.
This 17.0 μm double-side single-coated separator combines a 12 μm PE base with 2 μm CCS alumina ceramic and 2 μm PCS PVDF coatings, delivering a balanced profile of thermal-shrinkage resistance, electrode adhesion, and mechanical integrity (puncture strength 526 g, MD tensile 1533 kgf/cm²) for advanced battery R&D. Its 217.8 sec/100 ml air permeability and 40% porosity support ionic transport, though the low elongation at break (MD/TD 0.7%/0.6%) and 140 °C PE melting point impose handling and thermal constraints.
Positive
- Enhanced thermal-shrinkage resistance: The 2 μm CCS alumina ceramic coating on each side improves dimensional stability at elevated temperatures, reducing thermal-shrinkage risk during battery operation or drying processes.
- PVDF coating enables electrode bonding: The 2 μm PCS PVDF layer on the opposite side can bond the positive-electrode sheet to the separator, simplifying cell assembly and improving interfacial contact in stacked or wound configurations.
Trade-offs
- Low elongation at break: Elongation at break is only 0.7% MD and 0.6% TD, indicating low ductility that requires careful handling during winding or lamination to avoid cracking or edge damage.
- PE melting point limits thermal budget: With a PE melting point of approximately 140 °C, the separator cannot withstand high-temperature processing or operation above this threshold, restricting certain drying or hot-press steps.
