Key Features & Advantages
  • Homogeneous Material Purity: Features an uncompromised structural configuration with highly uniform elemental distribution across the matrix.
  • Enhanced Operational Efficiency: Specifically engineered to demonstrate superior electrochemical performance, significantly boosting transfer kinetics at targeted bands.
  • Optimized Sintering/Microstructure: Advanced synthesis allows for lower required operating temperatures and ideal grain boundary integration during cell fabrication.

APPLICATION SCOPE: Premium wet process PE separator for R&D layouts, high-capacity lithium-rich manganese-based secondary coin/pouch cell validation configurations.
PACKAGING: Hermetically packaged within advanced plastic-sealed bags combined with high-density internal cushion pads to protect the structural matrix against transportation stress.
IMPORTANT NOTICE: This product is highly sensitive to ambient exposure. Keep containers tightly sealed or handle exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation. Storage Environment: Sealed and stored in a normal or low temperature, dry, and ventilated environment. Notes: Keep away from fire and heat sources; Avoid sun exposure, fire baking, and rain during transportation.

This separator requires controlled storage and handling to maintain performance integrity. It must be kept sealed in a dry, ventilated environment away from heat sources and direct sunlight during transportation and storage.

  • Storage Environment: Store the separator sealed in a normal or low temperature, dry, and ventilated environment to prevent moisture absorption and degradation.
  • Thermal and Fire Safety: Keep the separator away from fire, heat sources, and direct sunlight to avoid thermal shrinkage or fire hazard.
  • Transportation Protection: Avoid exposure to rain, fire baking, and sun during transportation, and use cushion pads to prevent physical damage.
  • Battery Compatibility: This separator is specifically designed for Li-rich Mn-based battery systems and may not be suitable for other chemistries without validation.
  • Mechanical Handling: Handle the film with care to avoid puncture or tearing that could compromise battery safety.

How does the puncture strength of the Atomfair Dry PP 16μm separator compare to wet process PE separators of similar thickness?

The 16 μm dry PP separator has a puncture strength of 167 g, which is lower than the 535 g puncture strength of the 16 μm wet process PE separator (AF-PE16) listed in the same product family. However, the dry PP separator provides a significantly higher melting temperature of 167 °C compared to 135 °C for PE, making it more suitable for Li-rich Mn-based battery chemistries that operate at elevated temperatures.

Why is this dry PP separator specifically recommended for Li-rich Mn-based batteries?

This separator is engineered for Li-rich Mn-based batteries because it combines a high melting temperature of 167 °C with near-zero transverse thermal shrinkage (0% TD) and low longitudinal shrinkage (1.6% MD), ensuring dimensional stability under the high voltages and thermal stress typical of this cathode chemistry. The dry process also avoids solvent residues that could degrade battery performance, and the 41% porosity with 210 s air permeability balances ionic transport and mechanical integrity.

What are the recommended storage and handling conditions to maintain the integrity of this dry PP separator?

The separator must be stored sealed in a normal or low temperature, dry, and ventilated environment, away from fire and heat sources. It is packaged in plastic-sealed bags with cushion pads to prevent physical damage during transport and handling. Avoid sun exposure, fire baking, and rain, as the PP base film has a melting point of 167 °C and can degrade if exposed to excessive heat or moisture.

This 16μm dry-process PP separator offers high puncture strength and low thermal shrinkage, making it suitable for Li-rich Mn-based batteries, but requires controlled storage and careful handling due to anisotropic tensile properties.

Positive

  • High puncture strength: Puncture strength of 167 g provides robust mechanical integrity, critical for preventing internal shorts in Li-rich Mn-based battery cells.
  • Low thermal shrinkage: Transverse thermal shrinkage is 0% and longitudinal shrinkage is only 1.6%, ensuring dimensional stability during battery assembly and operation.

Trade-offs

  • Controlled storage required: Must be stored sealed in a dry, ventilated, low-temperature environment away from heat sources and sunlight, adding logistical constraints for lab inventory.
  • Anisotropic tensile strength: Longitudinal tensile strength (140 kg/cm³) is significantly lower than transverse (380 kg/cm³), requiring orientation-aware handling to avoid tearing during cell winding.
