Constraints

This aluminum-laminated film requires precise heat-seal temperature, pressure, and dwell time to meet specified seal strength and post-electrolyte peel strength. The material's formability is limited to a maximum depth of 5 mm to avoid barrier layer defects during pouch cell forming.

Heat-Seal Parameters: Maintain heat-seal temperature and pressure within the recommended window to achieve ≥40 N/15mm seal strength and ≥5 N/15mm post-electrolyte peel strength.
Electrolyte Compatibility: The inner CPP layer must resist chemical attack from common lithium-ion battery electrolytes to prevent delamination during extended cycling.
Formability Limit: Do not exceed the maximum forming depth of 5 mm to avoid pinhole formation or rupture of the aluminum barrier layer.
Puncture Resistance: Ensure all handling and forming tools are free of sharp edges to preserve the film's puncture resistance ≥18 N.
Storage Conditions: Store rolls in a clean, dry, and temperature-controlled environment to protect the adhesive layers and maintain bond integrity.

FAQ

How does the cost-effectiveness of the DM-L086N 86 μm aluminum-laminated film affect its performance in terms of barrier and mechanical properties compared to higher-grade alternatives?

The DM-L086N film delivers a balanced set of barrier, formability (≥5 mm), and electrolyte stability at a competitive price. It achieves heat-seal strength ≥40 N/15mm, puncture strength ≥18 N, and tensile strength ≥80 N/15mm, meeting mainstream pouch cell requirements while remaining ideal for R&D and small-batch production. Users prioritizing ultra-high barrier or deeper draw may need thicker films.

Is the DM-L086N aluminum-laminated film compatible with lithium-iron-phosphate (LFP) or high-nickel NMC cathode chemistries?

The film's inner CPP layer provides superior electrolyte corrosion resistance, with post-electrolyte peel strength ≥5 N/15mm and heat-seal strength ≥30 N/15mm. It is suitable for conventional pouch cell electrolytes used in LFP and standard NMC systems, but validation is recommended for high-voltage or aggressive solvent formulations.

What storage and handling conditions are critical to preserving the peel strength and formability of the DM-L086N film during pouch cell assembly?

To maintain the film's peel strength (CPP/AL ≥6 N/15mm) and formability (≥5 mm), store the roll in a cool, dry place away from UV and mechanical stress. During assembly, avoid sharp bends or punctures that could reduce the barrier integrity indicated by the puncture strength ≥18 N.

Assessment

This 86μm aluminum-laminated film delivers robust formability (≥5 mm) and electrolyte stability for pouch cell prototyping, though its fixed 200mm width and ±5% thickness tolerance impose process calibration and dimensional constraints for non-standard cell designs.

Positive

Excellent Formability for Deep Drawing: Formability ≥5 mm enables conventional pouch cell deep-drawing without cracking or delamination, accommodating edge folding and stamping in pilot lines.
Superior Electrolyte Corrosion Resistance: The inner CPP layer maintains heat-seal and peel strength after electrolyte immersion, with post-immersion peel strength ≥5 N/15mm and no swelling or delamination.

Trade-offs

Standard Dimensions Limit Flexibility: Supplied as 200mm × 10m rolls only; custom dimensions require separate inquiry, restricting adaptability for non-standard pouch cell formats.
Thickness Tolerance Requires Calibration: Thickness tolerance of ±5% (86 ± 4.3 μm) may necessitate process adjustments for consistent heat sealing and thermal management in precision assembly.
