Key Features & Advantages
  • High Cross-Directional Rigidity: Features a uniaxially processed dry PP infrastructure achieving a superior 414 kg/cm³ TD tensile strength, heavily protecting against deformation during cell compression.
  • Advanced Thermal Safeguards: Micro-engineered configuration delivers an elevated 167 °C melting point with minimal shrinkage profiles (1.1% MD / 0.1% TD) to eliminate internal short-circuit hazards under thermal stress.
  • Homogeneous Porous Channels: Calibrated with a steady 40% porosity and 355S air permeability, optimized to provide stable chemical transport lanes and excellent electrolyte wetness.

APPLICATION SCOPE: Highly optimized for Lithium-Rich Manganese-Based Battery configurations, electrochemical prototyping, and advanced energy storage system validation.
PACKAGING: Securely packed inside professional plastic-sealed bags reinforced with an internal impact-absorbing buffer pad matrix.
STORAGE CONDITIONS & PERFORMANCE NOTICE: Sealed and stored in a normal or low temperature, dry, and well-ventilated environment. Keep away from fire and heat sources; avoid exposure to direct sunlight, fire baking, and rain during transportation to suppress matrix contamination before automated laboratory assembly.

This separator requires sealed storage in a dry, low-temperature environment to prevent moisture uptake and contamination. It must be kept away from heat sources and sunlight to avoid thermal degradation.

  • Storage Sealing: Always reseal the separator in its original plastic bag after use to maintain a moisture-free environment.
  • Environmental Conditions: Store the sealed bag in a dry, well-ventilated area at normal or low temperature, avoiding humid or damp locations.
  • Heat and Light Avoidance: Keep the separator away from open flames, radiators, and direct sunlight to prevent heat shrinkage or degradation.
  • Transportation Protection: Protect the separator from rain, direct sunlight, and physical impact during transportation to avoid damage.

Follow these steps to ensure the separator remains dry and uncontaminated before use. Proper storage prevents loss of performance due to moisture or heat exposure.

Required Equipment: Plastic-sealed storage bag

  1. Seal the bag
    Seal the separator inside its original plastic bag after each use to prevent moisture ingress.
  2. Place in storage
    Place the sealed bag in a dry, well-ventilated storage area with a stable low temperature.
  3. Avoid hazards
    Keep the storage location away from open flames, heat sources, and direct sunlight at all times.

What is the trade-off between the high melting temperature of 167°C and the air permeability of 355 seconds in this dry-process PP separator for Li-rich manganese-based batteries?

The 167°C melting temperature provides superior thermal shutdown safety for Li-rich manganese-based cells operating at elevated temperatures, but the air permeability of 355 seconds indicates a denser pore structure, which may increase ionic resistance compared to separators with lower permeability values. This trade-off is acceptable for applications requiring enhanced thermal stability at the cost of slightly reduced rate capability.

Is this dry-process PP separator chemically compatible with the high-voltage electrolyte systems used in Li-rich manganese-based batteries?

Yes, this separator is specifically designed for Li-rich manganese-based batteries and is fabricated from polypropylene (PP) with a porosity of 40% and an areal density of 11.5 g/m², which provides good wettability and chemical resistance to common carbonate electrolytes. However, like all dry-process PP separators, it lacks ceramic coating, so compatibility at the high charge voltages typical of Li-rich manganese-based cathodes should be confirmed through accelerated aging tests.

What storage and handling precautions are required to prevent dimensional distortion of this 20 μm PP separator?

The separator must be stored sealed in a dry, well-ventilated environment at normal or low temperature, away from fire and heat sources. The longitudinal heat shrinkage of 1.1% and transverse shrinkage of 0.1% indicate that improper exposure to temperatures near its melting point of 167°C could cause irreversible dimensional changes; therefore, transportation should avoid direct sunlight and rain.

The Atomfair Dry-process PP Separator 20μm offers low heat shrinkage and high mechanical strength optimized for Li-rich manganese-based batteries, but its high air permeability and strict storage requirements are operational considerations.

Positive

  • Low Heat Shrinkage: Longitudinal heat shrinkage of 1.1% and transverse shrinkage of 0.1% ensure dimensional stability during battery assembly and thermal cycling.
  • High Mechanical Strength: Puncture strength of 167 g and transverse tensile strength of 414 kg/cm³ provide robust mechanical integrity against dendrite penetration and handling stresses.

Trade-offs

  • High Air Permeability: Air permeability of 355 seconds indicates relatively high resistance to gas flow, which may limit ionic transport and rate capability in high-power applications.
  • Strict Storage Conditions: Requires sealed storage in a normal or low temperature, dry, well-ventilated environment away from fire, heat, and UV exposure, imposing specific handling and inventory requirements.
