This punched aluminum-plastic film is designed for pouch cell battery assembly with specified hot sealing and laminate strength constraints. Proper processing within the defined temperature, pressure, and cleanliness limits is required to avoid delamination, contamination, or seal failure.
- Hot Sealing Parameters: Seal at 180-190°C with 0.2 MPa pressure for 2 seconds to achieve minimum heat seal strength of 29.4 N/15 mm.
- Laminate Strength Requirements: Maintain nylon/aluminum adhesion above 2 N/15 mm and aluminum/CPP adhesion above 5 N/15 mm to prevent delamination.
- Solvent Retention Limit: Keep residual solvents below 5 mg/m² to avoid electrolyte contamination.
- Moisture and Oxygen Barrier: Limit moisture vapor and oxygen transmission to 200 ppm over 5 years to preserve cell integrity.
- Molding Depth and Slip Factor: Ensure molding depth exceeds 5.0 mm and CPP/CPP slip factor remains below 1.0 for reliable pouch forming.
What laminate strength values are specified for this aluminum-plastic film and why are they critical for pouch cell reliability?
The film requires Nylon/Al laminate strength greater than 2 N/15 mm and Al/CPP laminate strength greater than 5 N/15 mm, with heat seal strength exceeding 29.4 N/15 mm at 200°C, 0.2 MPa, and 2 seconds. These values ensure robust interlayer adhesion and seal integrity, which are essential for preventing delamination and leakage during battery assembly and cycling.
What hot sealing conditions are required to achieve the specified heat seal strength for this punched aluminum-plastic film?
The recommended hot sealing temperature range is 180–190°C, with a test condition of 200°C at 0.2 MPa for 2 seconds yielding a heat seal strength greater than 29.4 N/15 mm. The polypropylene layer (0.040 mm ±0.004 mm) is designed for heat sealing, and these parameters ensure consistent seal quality for pouch cell assembly.
What critical quality control parameters affect the handling and long-term performance of this aluminum-plastic film in pouch cells?
Key parameters include solvent retention less than 5 mg/m², slip factor (CPP/CPP) less than 1.0, and moisture vapor transmission rate of 200 ppm over 5 years. These specifications ensure low outgassing, proper film stacking during handling, and adequate moisture barrier integrity to prevent electrolyte degradation and gas evolution over the battery's lifetime.
This punched aluminum-plastic film provides high laminate and heat seal strength for pouch cell assembly, but requires precise hot sealing conditions at 180-190°C and is limited to fixed dimensions.
Positive
- High laminate and seal strength: Laminate strength exceeds 2 N/15 mm for Nylon/Al and 5 N/15 mm for Al/CPP, with heat seal strength over 29.4 N/15 mm, ensuring robust pouch integrity.
- Low solvent retention and good barrier: Solvent retention is less than 5 mg/m² and moisture vapor transmission rate is 200 ppm over 5 years, providing effective protection for battery electrolytes.
Trade-offs
- Fixed punched dimensions: The film is pre-punched to L62×W46×T3 mm, limiting its use to pouches of that exact size without custom modification.
- Narrow hot sealing temperature range: Hot sealing requires 180-190°C, necessitating precise temperature control equipment and potentially incompatible with lower-temperature sealers.
