This dry-process polypropylene separator must be stored in a sealed, dry, and ventilated environment away from heat sources and flammable materials. The film is susceptible to puncture and dimensional changes from thermal exposure and requires careful handling to avoid mechanical damage.
- Storage Environment: Store the separator in a sealed container at normal or low temperature in a dry and ventilated area to prevent moisture absorption and thermal degradation.
- Fire and Heat Avoidance: Keep the separator away from open flames, heat sources, and flammable or explosive items to prevent ignition or material property changes.
- Mechanical Handling: Handle the separator carefully during transport and use to avoid severe collision, extrusion, or puncture that could compromise its structural integrity.
- Thermal Exposure: Avoid prolonged exposure to temperatures approaching the melting point (167°C) as this can cause thermal shrinkage and loss of mechanical strength.
- Light Sensitivity: Protect the separator from direct sunlight and rain during transportation and storage to maintain its performance characteristics.
How does the puncture strength of 380g in this 16μm dry-process PP separator correlate with its porosity and air permeability for lithium-ion battery applications?
The 380g puncture strength and 41% porosity represent a targeted balance between mechanical robustness and ionic transport. With an air permeability of 210 seconds, this separator allows adequate electrolyte wetting while maintaining structural integrity under compression.
What implications does the anisotropic tensile strength (MD 140 vs TD 17 kg/cm³) have for cell winding and assembly equipment?
The longitudinal tensile strength of 140 kg/cm³ is approximately eight times higher than the transverse strength of 17 kg/cm³, indicating strong directionality from the dry-process orientation. This requires careful alignment of the machine direction during winding to avoid tearing in the transverse direction when handling or during cell stacking.
What temperature and handling precautions are necessary to prevent thermal shrinkage and dimensional distortion of this PP separator?
The separator exhibits 1.6% longitudinal shrinkage and 0% transverse shrinkage, so it must be stored away from heat sources and at normal or low temperatures in a dry, ventilated environment. During transportation, avoid sunlight, fire, rain, and severe mechanical shock to prevent performance degradation.
This 16μm dry-process PP separator offers a high puncture strength of 380g and a melting temperature of 167°C, but its 1.6% MD thermal shrinkage and strict storage requirements (sealed, low-temperature, dry, and impact-free) impose handling and integration constraints for battery research applications.
Positive
- High puncture strength: At 380g, the separator provides robust mechanical resistance to electrode penetration, reducing short-circuit risk during cell assembly and compression.
- Elevated melting temperature: With a melting point of 167°C, the separator maintains structural integrity under moderate thermal stress, improving safety in high-temperature or abusive cycling scenarios.
Trade-offs
- Longitudinal thermal shrinkage: The 1.6% MD shrinkage at elevated temperatures may cause dimensional changes during battery drying or electrolyte filling, requiring careful process control.
- Sensitive storage and handling: The product must be stored sealed in a low-temperature, dry, ventilated environment away from heat and ignition sources, and transported with care to avoid collision or extrusion.
