This separator must be stored sealed in a dry, ventilated environment away from heat and ignition sources. Handle the film carefully to prevent puncture, creasing, or excessive tensile stress during battery assembly.
- Thermal Shrinkage Constraint: The separator exhibits 1.2% longitudinal and 0.1% transverse thermal shrinkage at elevated temperatures; avoid exposure to temperatures near the 135°C melting point.
- Storage Condition Requirement: Store the product in its sealed packaging under dry, cool conditions and away from flammable materials to prevent environmental degradation.
- Mechanical Handling Constraint: Avoid severe collision, extrusion, or puncture during handling and transport to maintain the film's integrity.
- Humidity Sensitivity: Maintain low humidity storage to prevent moisture absorption which could affect the separator's properties.
- Ignition Source Proximity: Keep the separator away from open flames and heat sources as the polyethylene film is combustible.
This procedure outlines the safe handling and storage steps for the PE separator to preserve its properties. Follow these steps to avoid physical damage and environmental exposure during preparation.
Required Equipment: Clean, dry hands or lint-free gloves
- Inspect Packaging
Inspect the sealed packaging for any damage or punctures before opening. - Store Properly
Store the unopened separator roll in a cool, dry, ventilated area away from heat and ignition sources. - Handle with Care
Handle the separator with clean, dry hands or gloves and avoid bending or creasing the film during assembly. - Transport Safely
Protect the separator from direct sunlight, rain, and mechanical shock during transportation.
How does the 39% porosity and 535 g puncture strength of the Atomfair AF-PE16 separator affect its ionic conductivity and mechanical integrity in battery cells?
The AF-PE16 separator balances ion transmission and mechanical strength with a porosity of 39% and puncture strength of 535 g. The 224 S air permeability supports adequate ionic conductivity, while the 16 μm thickness and 192/156 kg/cm³ tensile strengths (MD/TD) provide robust mechanical integrity. This trade-off is suitable for research where both safety and performance are critical.
What are the key differences between the wet-process PE separator (AF-PE16) and dry-process PP separators (AF-PP16) for lithium-ion battery assembly?
The AF-PE16 wet-process PE separator has a melting temperature of 135°C, lower than the 167°C of dry-process PP separators, making PE more prone to thermal shutdown but also providing a safety mechanism. The PE separator exhibits lower longitudinal thermal shrinkage (1.2% MD vs 1.6% for PP), higher puncture strength (535 g vs 380 g for PP), and significantly higher transverse tensile strength (156 kg/cm³ TD vs 17 kg/cm³ for PP), indicating better mechanical robustness in the transverse direction.
What are the recommended storage conditions and handling precautions for the Atomfair wet-process PE separator to prevent performance degradation?
The separator must be stored sealed in a normal or low temperature, dry, and well-ventilated environment, away from fire, heat sources, and flammable materials. During transportation, avoid sunlight, fire, rain, severe collision, and extrusion to maintain integrity. The plastic-sealed bag and cushion pad packaging ensure protection during transport and storage.
This 16μm wet-process PE separator delivers a balance of mechanical strength (535g puncture) and moderate porosity (39%) for lab-scale battery research, though its 135°C melt temperature imposes a ceiling on thermal endurance.
Positive
- High puncture strength for assembly: With a puncture strength of 535 g, the separator resists mechanical damage during electrode stacking or winding, reducing short-circuit risk in experimental cells.
- Low transverse thermal shrinkage: Transverse thermal shrinkage (TD) of only 0.1% ensures minimal dimensional change under moderate heat, preserving electrode alignment and cell integrity.
Trade-offs
- Limited thermal stability ceiling: The melting temperature of 135 °C constrains the upper operating limit, making the separator unsuitable for high-temperature battery cycles or drying steps near that threshold.
- Sensitive storage and handling required: The product must be stored sealed in a dry, well-ventilated environment away from fire, heat, and flammable materials, and transported without exposure to sunlight, rain, or strong impact.
