Key Features & Advantages
  • Balanced Performance for Power Applications: At 16µm thickness with 8.8 g/m2 area density and 535 gf puncture strength, this separator provides an optimal balance between mechanical robustness and ionic conductivity, ideal for power battery R&D and pilot-scale production.
  • Superior Thermal Shutdown Safety: 135°C melting temperature with proven shutdown characteristics. During thermal runaway events, rapid pore closure blocks ion conduction, effectively mitigating internal short-circuit risks for power and consumer LIB applications.
  • Exceptional Dimensional Stability: TD thermal shrinkage as low as 0.1% (90°C/2h) ensures outstanding dimensional stability under elevated temperatures. MD tensile strength of 192 MPa supports high-speed winding processes with consistent mechanical integrity.
  • Optimized Porosity & Electrolyte Wetting: 39% porosity with Gurley value of 224 s/100ml delivers excellent electrolyte wettability and unobstructed ion transport, perfectly suited for high-rate charge/discharge, long-cycle battery tests, and pilot-scale validation.

APPLICATION SCOPE: Power lithium-ion battery R&D, consumer electronics battery testing, pilot-scale production validation, high-rate charge/discharge experiments, long-cycle battery evaluation, and academic research on separator mechanical properties and thermal safety.
PACKAGING: Sealed plastic bag with protective cushion pad; room temperature/low temperature dry storage, protected from sunlight, high-temperature baking, and rainwater immersion during transport.
IMPORTANT NOTICE: This separator is sensitive to ambient moisture and mechanical damage. Keep packaging sealed until use. Store in dry, cool conditions away from heat sources. Handle with clean gloves to avoid contamination that may affect electrochemical performance.

Store sealed in a dry, well-ventilated environment below 135°C and away from fire or heat sources. Material integrity is compromised by excessive tensile load, puncture, or exposure to moisture.

  • Thermal Degradation Risk: The separator undergoes longitudinal shrinkage of 1.2% and transverse shrinkage of 0.1% at elevated temperatures, with complete melting at 135°C.
  • Moisture Sensitivity: Humid storage conditions can alter the porous structure and degrade electrolyte wetting performance.
  • Mechanical Damage Risk: Puncture or tensile overload during handling can create defects that lead to internal short circuits in the assembled cell.
  • Fire Hazard Consideration: Polyethylene is flammable; maintain separation from open flames, sparks, and ignition sources.

How does the 39% porosity and 224s air permeability of the 16μm wet-process PE separator affect its ionic conductivity versus mechanical integrity in lithium-ion battery R&D?

The 39% porosity and 224s air permeability of the AF-PE16 separator provide a balanced trade-off between ionic conductivity and mechanical integrity for R&D lithium-ion cells. This porosity level, combined with a puncture strength of 535g and tensile strengths of 192 kg/cm³ MD and 156 kg/cm³ TD, offers sufficient electrolyte retention and wetting while maintaining structural safety during assembly and cycling.

Can the wet-process PE 16μm separator be used with high-nickel NMC cathodes or silicon anodes that require high-temperature stability?

The AF-PE16 separator has a melting temperature of 135°C, which limits compatibility with high-temperature electrode processing or operation above that threshold. Its longitudinal thermal shrinkage is 1.2% and transverse shrinkage is 0.1%, indicating good dimensional stability at moderate temperatures, but it is not recommended for cells designed for operating above 135°C or requiring PP's higher melt integrity at 167°C.

What are the required storage and handling conditions to prevent contamination or degradation of the 16μm wet-process PE separator before use?

Store the separator sealed in a dry, well-ventilated environment at normal or low temperature, away from fire, heat sources, and flammable materials. During transportation, avoid sunlight, rain, severe collision, and extrusion to prevent physical damage and maintain the 60mm width integrity and 16μm thickness uniformity.

This 16 μm wet-process PE separator from Atomfair offers a balanced combination of mechanical strength (535 g puncture) and thermal stability (0.1% TD shrinkage) suitable for R&D battery fabrication, though its PE construction limits upper temperature exposure to 135°C and moderate porosity (39%) may constrain high-rate ionic transport.

Positive

  • High puncture strength: Puncture strength of 535 g provides robust mechanical integrity against electrode particle penetration, critical for preventing internal short circuits in lab-scale battery assemblies.
  • Low transverse thermal shrinkage: Transverse thermal shrinkage of only 0.1% TD ensures dimensional stability across the separator width during thermal excursions, improving cell safety and consistency.

Trade-offs

  • Low melting temperature limit: Melting temperature of 135°C for the PE base film imposes a strict upper thermal operating limit; the separator loses structural integrity above this temperature, requiring careful thermal management during cell drying or battery testing.
  • Moderate porosity may limit rate: Air permeability of 224 S combined with 39% porosity indicates moderate ionic resistance; for high-rate or thick-electrode experiments, this separator may contribute to concentration polarization effects.
