  1. This PET double-sided composite aluminum foil uses an ultra-thin 8 \u03bcm battery-grade aluminum foil<\/strong> laminated with PET (polyethylene terephthalate) film on both sides<\/strong>. The aluminum layer serves as a lightweight, conductive current collector for lithium-ion cathodes, while the PET layers provide mechanical reinforcement, insulation, and improved puncture resistance. It is particularly suitable for laboratory cells, prototype pouch cells, and research on safer or structurally reinforced electrode designs.<\/li>\n

    \n

    We offer fully customizable PET\/Al\/PET laminates for scientific research and small-scale pilot experiments<\/strong>, including PET thickness, total laminate thickness, roll width, and cut-sheet formats. The composite foil is compatible with standard cathode slurry coating, drying, calendaring, and cell assembly processes used in Li-ion battery R&D. Technical data (aluminum purity, PET properties, thickness tolerances) and OEM\/ODM support are available to help you quickly integrate this 8 \u03bcm PET composite aluminum foil into new material studies and experimental cell structures.<\/p>\n

    Width & Length<\/td>\nRoll width from tens of millimeters up to several hundred millimeters (lab\/pilot scale); roll length configurable according to thickness and order quantity<\/td>\n<\/tr>\n
    Bonding Method<\/td>\nPET films laminated to aluminum via adhesive or adhesive\u2011less thermal lamination to ensure strong adhesion and dimensional stability during drying and calendaring<\/td>\n<\/tr>\n
    Interface Quality<\/td>\nGood PET\u2013Al adhesion to avoid delamination under electrode coating, drying, calendaring, slitting, and assembly conditions<\/td>\n<\/tr>\n
    Mechanical Properties<\/td>\nHigher tensile strength, tear and puncture resistance, and handling robustness compared with bare ultra\u2011thin Al foil; suitable for manual and automated lab handling<\/td>\n<\/tr>\n
    Surface Finish (Al side)<\/td>\nAluminum surface available bare or pre\u2011treated (cleaned\/roughened) to improve slurry wetting and adhesion for cathode coatings<\/td>\n<\/tr>\n
    Thermal & Chemical Stability<\/td>\nCompatible with common cathode slurry systems and drying temperatures used in Li\u2011ion R&D, within PET thermal limits<\/td>\n<\/tr>\n
    Dimensional Tolerances<\/td>\nTight control of Al and PET thickness, width, and flatness to ensure uniform coating, stable web transport, and consistent electrode quality<\/td>\n<\/tr>\n
    Application Range<\/td>\nLithium\u2011ion and other lithium\u2011based experimental cells: prototype pouch\/coin\/prismatic cells, reinforced\/safety\u2011enhanced cathodes, and novel cell architecture research<\/td>\n<\/tr>\n
    Processing Capability<\/td>\nSuitable for standard cathode slurry coating, drying, calendaring, slitting, die\u2011cutting, stacking\/winding, and pouch sealing processes in laboratory and small pilot production<\/td>\n<\/tr>\n
    Customization<\/td>\nTailored PET thickness (one or both sides), Al thickness (e.g. 8 \u03bcm or other), roll width\/length, Al surface treatment, and sheet formats according to customer drawings and equipment requirements<\/td>\n<\/tr>\n
    Packaging<\/td>\nSupplied in clean, dust\u2011protected rolls or sheets with moisture\u2011barrier packing; core and edge protection; outer carton or wooden case for safe storage and international transport<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/li>\n<\/ol>\n
