Key Product Features & Benefits
  • Engineered Trilayer Structure: The specialized PP/PE/PP structural configuration matches the robust mechanical strength of polypropylene outer matrices with the low-temperature shutdown protection of a polyethylene core layer.
  • Outstanding Thermal Stability: Exhibits minimal structural contraction under high temperatures, reducing the risk of internal short-circuits and thermal runaway.
  • Optimized Low Resistance: The porous three-layer design optimizes ion transport kinetics, significantly upgrading battery delivery rates and efficiency.
  • Longer Functional Lifespan: Exceptional chemical compatibility with battery environments blocks breakdown pathways, maintaining testing integrity.

Target Application Fields
  • Lithium-Ion Battery Prototyping: An ideal separation component deployed across electric vehicles (EV), premium consumer electronics, and stationary grid storage.
  • High-Performance Battery Systems: Excellently configured for devices demanding heightened energy density thresholds paired with fast charge/discharge capabilities.
  • Renewable Energy Management: Highly effective for validating storage systems connected to commercial solar arrays and wind harvesting grids.

QUALITY REGULATION: Microstructural porosity parameters and composite layer weights adhere strictly to baseline [ISO 9001 quality validation] protocols to maximize testing uniformity.
PACKAGING LOGISTICS: Dispatched securely as precise continuous rolls or custom sheets of PP/PE/PP trilayer material based on instructions.
STORAGE RECOMMENDATIONS: Store inside a clean, dry, and cool location completely sheltered away from environmental humidity to maintain structural integrity.
IMPORTANT NOTICE: Transfer and slice current collector roll modules within dust-free cleanroom environments to shield porous surfaces from particulate deposits.

Store in a cool, dry environment to prevent material degradation and maintain performance. Ensure compatibility with battery electrolytes to avoid chemical deterioration and maintain ionic conductivity.

  • Thermal stability constraint: The separator exhibits high thermal stability to reduce thermal runaway risk but must not exceed its shutdown temperature.
  • Chemical resistance constraint: Resistant to common battery electrolytes and solvents, but verify compatibility with specific formulations.
  • Storage constraint: Store in a cool, dry place to maintain material integrity and prevent degradation.

How does the 20 μm thickness of this PP/PE/PP trilayer separator affect the balance between ionic conductivity and mechanical puncture resistance in lithium-ion batteries?

The 20 μm thickness provides low internal resistance for high ionic conductivity, enabling fast charge/discharge rates. Simultaneously, the trilayer structure with PP outer layers offers enhanced mechanical strength and puncture resistance compared to single-layer separators of similar thickness, reducing the risk of internal short circuits.

What customization options are available for width and length when integrating this separator into cylindrical versus pouch cell formats?

The standard width is 60 mm but is customizable to suit specific battery designs, including cylindrical and pouch cells. Length is available in various dimensions; for example, 500 m rolls are offered for continuous winding processes in cylindrical cell manufacturing or sheet cutting for pouch cells.

What storage conditions are required to prevent degradation of the PP/PE/PP trilayer separator's chemical resistance and thermal stability before use?

Store in a cool, dry place as specified by the manufacturer to maintain material integrity and performance. This prevents moisture absorption that could compromise chemical resistance to electrolytes and ensures the thermal stability of the polypropylene layers remains intact for safe battery operation.

This 20μm PP/PE/PP trilayer separator offers enhanced ionic conductivity and thermal safety for lithium-ion battery research, but requires climate-controlled storage to maintain integrity.

Positive

  • Trilayer structure optimizes ion transport: The PP/PE/PP trilayer design provides excellent ionic conductivity and mechanical strength, improving battery efficiency and durability.
  • High thermal stability enhances safety: The material exhibits high thermal stability, reducing the risk of thermal runaway during battery operation, which is critical for high-energy applications.

Trade-offs

  • Requires controlled storage environment: The separator must be stored in a cool, dry place to maintain material integrity and performance, necessitating climate-controlled laboratory or warehouse conditions.
