Al Film Pouch Materials for Battery Manufacturing

Targray offers a full line of aluminum laminated film pouch materials for all your lithium ion battery packaging applications, and a wide range of tabs for li-ion pouch cells. For long lifetime (calendar life and cycling) and error-free operation of lithium-ion battery cells, our aluminum laminated film pouches deliver many advantages:

  • Flexible pouch material allows for better system level battery design
  • Good vapor barrier
  • Excellent pouch sealing
  • Good anti-electrolyte resistance
  • Available in a roll format or pre-formed pouch
  • Provides excellent deep forming capability
  • Customized sizes available based on specific customer requirements

Aluminum Laminated Film – Product Specifications

Our broad selection of dry laminated aluminium can support any lithium-ion battery packaging application you are developing or manufacturing, from small cell manufacturing (mobile phone) to large vehicle cells. Including but not limited to: Mobile Phones/Smart Phones, Tablets, Laptops, E-Bicycles/E-Scooters, Power tools, EV, and Storage applications.

Pouches can be ordered in thicknesses 71 to 156 μm and in forming depths from 4.5mm to 8.0 mm. Multi layer pouches support a nylon layer, an AL foil layer, and a Cast Poly Propylene (CPP) layer. In addition, Targray can provide an integrated design of laminate pouches and tabs from a single source.

Li-ion Battery Tabs for Pouch Cells

Targray also supplies a full range of battery tabs for pouch cells, offering full integration with your pouch design. The tabs include a multi-layered polypropylene sealing film that offers several key benefits:

  • Exceptional Sealing Reliability in Electrolytic Solution
    • Test Condition: Dipped in Electrolyte (+water 100ppm) at 85°C
    • Result after 1000 hours: No defects (the film and conductor keep contact)
  • Nano-thickness Surface Treatment
    • Extremely thin surface treatment layer provides an advantage in welding reliability
    • We honor our commitments to end-customers and our stake-holders
  • High Corrosion Resistance
    • Test Condition: Salt spray at 35°C
    • Result after 1000 hours: No defects (film and conductor remain in contact and the surface of the conductor is protected from corrosion)

Working closely with our supply partners and organizations including the Electrochemical Society and NAATBatt International, we help lithium-ion battery manufacturers and researchers worldwide commercialize ambitious new technologies for the energy storage market. Contact us today to learn more.
