Key Features & Advantages
  • Ultra-Thin Design for High Energy Density: At 9µm thickness with 5.7 g/m2 area density, this separator enables maximum electrode loading and enhanced energy density in next-generation lithium-ion battery designs without compromising safety or performance.
  • Superior Thermal Shutdown Safety: 135°C melting temperature with proven shutdown characteristics. During thermal runaway events, rapid pore closure blocks ion conduction, effectively mitigating internal short-circuit risks for consumer electronics and high-energy 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. MD tensile strength of 221 MPa and puncture strength of 410 gf support high-speed winding processing with robust mechanical integrity.
  • Optimized Porosity & Ionic Conduction: 38% porosity with Gurley value of 185 s/100ml delivers excellent electrolyte wettability and unobstructed ion transport, perfectly suited for high-rate charge/discharge and long-cycle battery test scenarios.

APPLICATION SCOPE: High-energy-density LIB R&D, consumer electronics battery testing, power lithium-ion battery validation, high-rate charge/discharge experiments, long-cycle battery evaluation, and academic research on ultra-thin separator performance and 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 ultra-thin separator is highly 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 or puncture that may affect electrochemical performance.

This polyethylene battery separator is sensitive to ambient moisture and must be stored in a dry, ventilated environment below the melting point of 135°C. Mechanical integrity is compromised by puncture forces exceeding 566 g and thermal shrinkage exceeding 0.9% in the machine direction.

  • Moisture sensitivity: The separator must be kept sealed in a dry atmosphere to prevent water uptake which can degrade ionic conductivity and induce swelling.
  • Thermal exposure: Exposure to temperatures approaching 135°C will cause melting and loss of electrical isolation between electrodes.
  • Mechanical handling: Severe collision or extrusion during transport can exceed the puncture strength of 566 g and cause critical pinhole defects.

How does the mechanical strength of the 9μm wet PE separator compare to the 12μm variant, and what trade-offs exist for thin-film applications?

The 9μm separator delivers a higher longitudinal tensile strength of 221 kg/cm³ compared to 208 kg/cm³ for the 12μm variant, but its puncture strength drops to 410g from 566g. This trade-off improves ion transport via lower air permeability (185S vs 222S) at the cost of reduced puncture resistance, requiring careful handling during high-pressure cell assembly to avoid micro-shorts.

What are the thermal shrinkage properties of the 9μm PE separator and how do they affect cell lamination and safety?

The separator exhibits longitudinal thermal shrinkage of 1.5% and transverse shrinkage of only 0.1%, with a melting temperature of 135°C. The minimal transverse shrinkage ensures stability during lamination, while the 1.5% MD shrinkage must be accounted for in electrode alignment to prevent internal shorts, and the 135°C shutdown temperature provides a safety mechanism against thermal runaway.

What storage conditions are critical to preserve the porosity and permeability of this wet PE separator for reproducible battery research?

The separator must be stored sealed in a dry, well-ventilated environment at normal or low temperature, away from fire and flammable materials. Air permeability of 185 seconds and porosity of 38% are susceptible to moisture and heat; therefore, immediate resealing after use and avoidance of sunlight or rain exposure are mandatory to maintain consistent performance across experiments.

This 12 μm wet-process PE separator provides high tensile strength (MD 208 kg/cm³) and puncture resistance (566 g) with low thermal shrinkage (MD 0.9%, TD 0.1%), ideal for battery research requiring mechanical robustness. However, its melting point of 135°C and requirement for dry, sealed storage impose operational constraints.

Positive

  • High mechanical strength: Longitudinal tensile strength of 208 kg/cm³ and puncture strength of 566 g provide robust isolation between electrodes, reducing short-circuit risk during cell assembly and cycling.
  • Low thermal shrinkage: MD shrinkage of only 0.9% and TD shrinkage of 0.1% at elevated temperatures ensure dimensional stability, maintaining separator integrity and ion transport pathways.

Trade-offs

  • Low melting temperature: A melting point of 135°C limits high-temperature applications and thermal runaway tolerance, requiring careful thermal management in battery testing.
  • Requires dry, sealed storage: The separator must be stored sealed in a dry, well-ventilated environment to prevent moisture absorption that could compromise ionic conductivity and mechanical properties.
