This separator must be stored in a sealed, dry, ventilated environment away from heat sources and flammable materials. Handle with care to avoid mechanical damage and environmental degradation.
- Storage Environment: Store the separator sealed in a dry, ventilated area at normal or low temperature.
- Fire and Chemical Safety: Keep the separator away from fire, heat sources, and flammable or explosive materials.
- Transportation Protection: During transport, avoid direct sun exposure, rain, fire, and severe impact or extrusion.
- Mechanical Integrity: Prevent severe collision and extrusion to maintain the separator's dimensional and functional integrity.
Follow these steps to preserve the separator's integrity for battery assembly. The material is sensitive to moisture, temperature, and mechanical stress.
- Inspect for Damage
Inspect the separator for any visible damage or contamination upon receipt. - Seal and Store
Store the separator in its original sealed packaging in a dry, ventilated environment at controlled temperature. - Isolate from Hazards
Keep the stored separator away from direct heat sources, open flames, and flammable materials. - Handle with Care
Handle the separator carefully during transportation and installation to avoid creasing or puncturing.
For high-temperature battery cycling, what performance trade-off exists between the longitudinal thermal shrinkage of 1.2% and the longitudinal tensile strength of 192 kg/cm³ in the 16 μm wet-process PE separator?
The 16 μm wet-process PE separator provides a balanced trade-off: a low MD thermal shrinkage of 1.2% at a melting temperature of 135°C, combined with an MD tensile strength of 192 kg/cm³, ensures dimensional stability during elevated-temperature operation while maintaining sufficient mechanical handling robustness. This makes it suitable for applications where both thermal integrity and machine-direction strength are critical.
Can this 16 μm wet-process PE separator be used as a direct replacement for the AF-PP16 dry-process PP separator in a cell stack without redesign?
Direct replacement is not recommended because the two separators differ significantly in mechanical and thermal properties: AF-PP16 has a lower MD tensile strength of 140 kg/cm³ vs. 192 kg/cm³, a lower puncture strength of 380 g vs. 535 g, and a higher melting temperature of 167°C vs. 135°C. These differences affect cell stack compression behavior and safety shutdown response, requiring re-optimization of cell assembly parameters.
What are the critical storage and handling requirements to prevent performance degradation of the 16 μm wet-process PE separator?
The separator must be stored sealed in a normal or low temperature, dry, and ventilated environment, away from fire, heat sources, and flammable materials. During transport, avoid sun exposure, fire baking, rain, severe collision, and extrusion to prevent mechanical damage or contamination that could compromise its 39% porosity and 224-second air permeability.
The Atomfair Wet-process PE Separator 16μm (AF-PE16) offers a balanced combination of mechanical strength and dimensional stability for battery R&D, with a puncture strength of 535 g and low transverse thermal shrinkage of 0.1%, but requires careful thermal management due to a melting point of 135°C and strict storage conditions to prevent performance degradation.
Positive
- High puncture strength: With a puncture strength of 535 g, this separator resists penetration by electrode particles, reducing short-circuit risk during cell assembly and cycling.
- Low transverse thermal shrinkage: Transverse thermal shrinkage of only 0.1% (TD) ensures minimal dimensional change in the width direction during drying or thermal processing, preserving alignment.
Trade-offs
- Low melting temperature: A melting temperature of 135°C limits safe operating temperatures and requires careful thermal management to avoid separator collapse or shutdown in high-temperature conditions.
- Strict storage requirements: Must be stored sealed in a normal or low temperature, dry, ventilated environment, away from fire and heat sources, to prevent moisture absorption and oxidative degradation.
