Logistics, Handling & Storage Requirements
  • Airtight Protective Packaging: Delivered securely inside an airtight, plastic-sealed containment bag with engineered internal cushioning to block environmental humidity.
  • Regulated Warehouse Storage: Must remain sealed in a temperature-controlled, dry, and clean environment. Store completely clear of fire hazard points, heat pipelines, or combustible matrices.
  • Transit Integrity Controls: Protect carefully against direct solar radiation exposure, sudden heat spikes, or unexpected precipitation during dispatch handling to avoid mechanical warping.

APPLICATION SCOPE: Standardized scientific testing and internal prototype validation loops for secondary lithium-ion, sodium-ion, and cutting-edge battery assemblies.
INSPECTION STANDARD: 100% automated visual and mechanical structural verification prior to laboratory distribution to maintain completely burr-free and oil-free operation.
IMPORTANT NOTICE: Handle with extreme care in cleanroom spaces or an anhydrous atmosphere to avoid structural wrinkles or particulate pollution. For explicit custom width, roll length, or alternative thickness options, please reach out to our team.

The separator must be stored in a sealed, dry, and well-ventilated environment away from heat sources. Avoid exposure to sunlight, moisture, and mechanical stress during handling to prevent degradation and failure.

  • Storage Environment: Store the separator in a sealed plastic bag within a normal or low temperature, dry, and well-ventilated area to prevent moisture absorption and thermal degradation.
  • Temperature Sensitivity: Keep away from fire, heat sources, and flammable materials to avoid melting or thermal shrinkage above 135°C.
  • Mechanical Integrity: Handle with care during transportation and storage to avoid puncture, creasing, or extrusion that could compromise the separator's barrier function.
  • Contamination Prevention: Seal the product in its original packaging when not in use to protect against airborne particulates and chemical contamination.

Proper handling and storage procedures maintain the physical integrity and performance of the wet-process PE separator. Follow these steps to prevent contamination, mechanical damage, and thermal degradation.

Required Equipment: Plastic-sealed storage bag

  1. Inspect packaging
    Inspect the outer packaging for tears, punctures, or moisture intrusion before opening the sealed bag.
  2. Store in controlled environment
    Transfer the separator to a sealed plastic bag and place it in a dry, well-ventilated storage area with low humidity.
  3. Isolate from heat and flame
    Keep the separator away from open flames, radiators, or any heat source exceeding 50°C to prevent thermal degradation.
  4. Handle with care
    Grasp the separator by its edges and avoid sharp objects or heavy pressure that could cause puncture or creasing.

How does the 535g puncture strength of this 16μm wet-process PE separator affect cell assembly yield compared to thicker alternatives?

The 16μm separator delivers a puncture strength of 535 g, which is a compromise between the 339 g of the 7 μm variant and the 722 g of the 20 μm version. This level provides adequate resistance against electrode particle penetration for typical research cell assembly, though extra care is required during stacking or winding to avoid micro-shorts that could lower yield.

Can this 16 μm PE separator accommodate the electrolyte wetting demands of high-nickel NMC cathodes given its 39% porosity and 224 s air permeability?

Yes, the 39% porosity and 224 s/100cc Gurley value are standard for wet-process PE separators used in conventional liquid electrolytes. However, for high-viscosity or high-loading electrode systems, the 224 s permeability may limit wetting speed, and pre-wetting or longer fill times may be needed to ensure uniform electrolyte distribution.

What storage and handling precautions are required for this 16 μm PE separator to prevent thermal shrinkage or moisture uptake before use?

The separator must be stored sealed in a dry, well-ventilated environment away from heat sources and direct sunlight, as its melting point is 135°C and longitudinal thermal shrinkage reaches 1.2%. Avoid exposure to temperatures exceeding 60°C during handling to preserve dimensional stability, and keep packaging airtight to prevent moisture adsorption that could increase air permeability or porosity variability.

The Atomfair AF-PE20 wet-process PE separator offers a balanced combination of high puncture resistance (722g) and low transverse shrinkage (0.1%), making it suitable for research cells. However, its 135°C melting point and 1.4% longitudinal shrinkage require careful thermal management during cell fabrication.

Positive

  • High puncture strength: Puncture strength of 722g provides strong resistance against electrode particle penetration, reducing short-circuit risk in cell assembly.
  • Low transverse thermal shrinkage: Transverse thermal shrinkage of only 0.1% ensures minimal width distortion, contributing to consistent electrode alignment during thermal processing.

Trade-offs

  • Low melting temperature: Melting temperature of 135°C imposes an upper thermal limit; exposure above this threshold can cause separator collapse and internal short circuits.
  • Moderate longitudinal shrinkage: Longitudinal thermal shrinkage of 1.4% at MD requires controlled drying and assembly conditions to prevent slack or misalignment in the cell stack.
