What is the air permeability range of the 30 μm PP/PE nonwoven battery separator and how does it affect battery performance?
The air permeability is 80-150 sec/100 ml, as stated in the product specifications. This range indicates the separator's resistance to gas flow, which is critical for preventing thermal runaway and ensuring consistent ionic transport in lithium-ion cells. The specified range is a key quality indicator for the separator's porosity and pore structure.
What are the tensile strength and water absorption specifications of this 30 μm PP/PE nonwoven separator, and how do they relate to handling and electrolyte wetting?
The separator has a tensile strength of 7.8 N/15 mm (0.8 kgf/15 mm) and a water absorption of 20 mm/10 min. The tensile strength ensures mechanical integrity during cell winding and assembly, while the water absorption value indicates the separator's ability to uptake electrolyte, which is essential for achieving low internal resistance and efficient ion transport. These properties are critical for reliable cell manufacturing and performance.
What are the key physical properties of this 30 μm PP/PE nonwoven separator, including density, basis weight, and porosity, and how do they influence its use in battery applications?
The separator has a density of 0.40 g/cm³, a basis weight of 12.0 g/m², and a porosity of 73%. These parameters determine the separator's mechanical strength, thermal stability, and ionic conductivity. The high porosity supports electrolyte retention and ion flow, while the density and basis weight contribute to the separator's overall robustness and consistency, which are essential for preventing internal short circuits.
This 30 μm nonwoven PP/PE separator base film, supplied as a 120 mm x 100 m roll, offers a balanced combination of high porosity (73%) and moderate air permeability (80-150 sec/100 ml), making it suitable for electrolyte wetting and ionic transport in battery cell prototyping. Its tensile strength of 7.8 N/15 mm and water absorption of 20 mm/10 min indicate adequate mechanical handling and wettability for lab-scale electrode assembly, though the uncoated surface and lot-to-lot variations require careful process validation.
Positive
- High porosity for ionic transport: The 73% porosity supports efficient electrolyte uptake and ionic conductivity, which is critical for battery performance in research cells.
- Balanced mechanical and wetting properties: Tensile strength of 7.8 N/15 mm and water absorption of 20 mm/10 min indicate adequate handling strength and electrolyte wetting for lab-scale assembly.
Trade-offs
- Uncoated surface limits thermal stability: The uncoated nonwoven structure may exhibit higher thermal shrinkage or lower dimensional stability at elevated temperatures, requiring careful handling during cell assembly and testing.
- Lot-to-lot variability in key parameters: Slight variations in thickness, porosity, or air permeability may occur between production lots, necessitating batch-specific validation for reproducible research results.
