Key Features & Advantages
  • Superior Thermal Shutdown Safety: Full-series melting temperature at 135°C with low-temperature shutdown characteristics. During thermal runaway events, rapid pore closure blocks ion conduction, effectively mitigating internal short-circuit risks for consumer and power LIB R&D.
  • Exceptional Dimensional & Mechanical Stability: TD thermal shrinkage as low as 0.1% (90°C/2h) ensures outstanding dimensional stability under elevated temperatures, drastically reducing shrinkage-induced internal failures. MD tensile ≥160 MPa supports high-speed winding processing.
  • Optimized Porosity & Electrochemical Performance: Porosity concentrated within 36–42% range with Gurley value of 224 s/100ml delivers excellent electrolyte wettability and unobstructed ionic conduction, perfectly suited for high-rate charge/discharge and long-cycle battery test scenarios.

APPLICATION SCOPE: Consumer-grade LIB, power lithium-ion battery R&D testing, high-rate charge/discharge experiments, long-cycle battery validation, and academic research on separator thermal safety.
PACKAGING: Sealed plastic bag with protective cushion pad; room temperature/low temperature dry storage, protected from sunlight, high-temperature baking, and rainwater immersion during transport.
IMPORTANT NOTICE: This separator is sensitive to ambient moisture and mechanical damage. Keep packaging sealed until use. Store in dry, cool conditions away from heat sources. Handle with clean gloves to avoid contamination that may affect electrochemical performance.

This wet-process polyethylene separator is moisture-sensitive and must be stored in sealed, dry, and well-ventilated conditions. Exposure to heat sources, open flames, or direct sunlight can cause thermal degradation and loss of dimensional stability, as the base film has a melting point of 135°C.

  • Moisture Protection: Maintain the separator in its original sealed plastic bag until immediately before use to prevent moisture absorption that could compromise dimensional stability and electrolyte compatibility.
  • Temperature Control: Store at normal or low temperature away from any heat source to avoid premature shrinkage or melting, noting the polyethylene film melts at 135°C.
  • Mechanical Integrity: Handle the 14 μm thick film with care to avoid punctures, tears, or creasing that can create defects during battery assembly.
  • Compatibility Verification: Confirm electrolyte and cathode formulation compatibility for lithium-rich manganese-based chemistries to prevent chemical swelling or dissolution of the separator.
  • Fire Safety: Keep the separator away from open flames, sparks, and ignition sources due to the combustible nature of polyethylene material.

How does the 14 μm thickness of this wet-process PE separator affect thermal shutdown performance for lithium-rich manganese-based cells?

The separator delivers a definitive melting temperature of 135°C for thermal shutdown, which is standard for PE separators. The 14 μm thickness reduces ionic resistance, but the separator is specially formulated for lithium-rich manganese-based batteries to balance this trade-off without compromising shutdown reliability.

What compatibility factors should be considered when integrating this separator into a lithium-rich manganese-based battery design?

This wet-process PE separator is explicitly designated as special for lithium-rich manganese-based batteries, indicating targeted optimization for the high-voltage environment of that chemistry. The 14 μm thickness and 135°C melting point are key parameters that align with the stability requirements of these cathodes, though specific porosity and shrinkage data are not provided for this variant.

What storage and handling precautions are required to maintain the integrity of this 14 μm wet-process PE separator?

Store the separator sealed in a normal or low temperature, dry, and well-ventilated environment. During transport, avoid sunlight, fire, baking, and rain. The product is packaged in a plastic sealed bag with buffer pad to prevent mechanical damage, and always keep away from fire and heat sources to preserve the 135°C melting point.

This wet-process PE separator at 14 μm thickness is tailored for lithium-rich manganese-based batteries, featuring a melting shutdown at 135°C for thermal safety. The thin film and strict storage environment requirements necessitate careful handling and environmental control during deployment.

Positive

  • Tailored for Lithium-rich Manganese-based Batteries: This separator is specifically formulated for compatibility with lithium-rich manganese-based cathode chemistries, ensuring optimized electrochemical performance and cycle life in that application.
  • Thermal Shutdown at 135°C: The PE base film has a melting temperature of 135°C, providing a safety shutdown mechanism that blocks ionic transport at elevated temperatures, thereby reducing thermal runaway risk.

Trade-offs

  • Strict Storage Environment Requirements: The separator must be stored sealed in a dry, well-ventilated environment away from heat sources and sunlight; exposure to moisture or temperature extremes can degrade performance.
  • Thin 14μm Film Requires Careful Handling: The 14 μm thickness increases risk of wrinkling or tearing during manual or automated handling; protective packaging with plastic sealed bag and buffer pad is essential to prevent damage.
