This dry-process polypropylene separator is specifically formulated for use in Li-rich manganese-based batteries. Storage requires sealed, low-temperature, dry, and well-ventilated conditions away from heat sources.
- Storage Environment: Store the sealed separator in a low-temperature, dry, and well-ventilated area away from fire and heat sources.
- Thermal Sensitivity: Avoid exposure to temperatures near the melting point of 167°C to prevent dimensional shrinkage and loss of structural integrity.
- Handling and Transport: Protect the separator from physical damage during transport using the provided plastic-sealed bag and buffer pad.
- Moisture Protection: Keep the separator sealed to prevent moisture absorption that could compromise its performance and compatibility with the battery electrolyte.
What is the trade-off between porosity and mechanical puncture resistance in the Atomfair AFSPPP16U60mm20m separator for Li-rich manganese batteries?
The separator achieves a porosity of 41% with a puncture strength of 167 g, balancing ionic conductivity and mechanical integrity. Higher porosity would increase ionic transport but reduce puncture resistance below 167 g, risking shorts from cathode debris. The 16 μm thickness and 140 kg/cm³ MD tensile strength provide sufficient handling durability while maintaining the 41% porosity.
Why is the Atomfair AFPP16 separator specifically recommended for Li-rich manganese-based battery chemistries?
The AFPP16 uses a dry-process PP base film with zero transverse heat shrinkage (TD 0%) and a melting temperature of 167°C, providing dimensional stability under the high operating voltages and temperatures typical of Li-rich manganese cathodes. The 16 μm thickness and 8.75 g/m² areal density reduce internal resistance while offering adequate mechanical support for the cathode volume changes during cycling.
What are the critical storage and handling conditions required to preserve the performance of the Atomfair dry-process PP separator?
The separator must be sealed in a plastic bag with buffer pad and stored in a normal or low temperature, dry, well-ventilated environment. It must be kept away from fire and heat sources during transport and storage, and protected from sunlight, rain, and fire baking to prevent degradation of the 16 μm PP film's porosity and shrinkage properties.
Dry-process PP separator optimized for Li-rich manganese-based batteries, offering 167°C melt temperature and zero transverse shrinkage, but requires careful dry storage and handling due to its 16μm thickness.
Positive
- High thermal stability for high-voltage cells: Melting temperature of 167°C provides a safety margin for Li-rich manganese-based chemistries that operate at elevated potentials.
- Zero transverse heat shrinkage: Transverse heat shrinkage of 0% ensures dimensional stability during electrode stacking and thermal processing, reducing short-circuit risk.
Trade-offs
- Demanding storage conditions: Must be kept sealed in a dry, well-ventilated, low-temperature environment, away from fire and heat sources, adding infrastructure requirements.
- Low puncture strength at 16μm thickness: Puncture strength of only 167g makes the film more susceptible to damage from electrode protrusions or handling, necessitating buffer-pad packaging.
