Product Description1235 1060 soft pack battery core special aluminum foil high conductivity
What is lithium battery foil
Use: Aluminum foil used inside lithium batteries as a positive current collector. It is a key component of battery cells.
Location: Located inside the battery, wound or stacked in the battery cell.
What is the function of lithium battery foil
Conductivity: Collect the current generated by the positive active material (such as lithium cobalt oxide, lithium iron phosphate, ternary materials, and conduct it to the battery tab.
Support: Provide mechanical support as a substrate for the positive active material coating.
Material and structure: Usually a single-layer plain foil made of pure aluminum or a specific aluminum alloy.
Advantages of YSA soft-pack battery core foil
High conductivity: Effectively improve energy efficiency and reduce internal resistance.
High purity: Reduce side reactions caused by impurities.
Excellent mechanical properties: Good tensile strength, elongation, and flexibility to adapt to coating, rolling, slitting, winding, lamination and other processes.
Good surface quality: The surface is clean, flat, and defect-free to ensure good adhesion and conductive contact with the active material coating.
Thickness Uniformity: The thickness consistency is extremely high.
Corrosion Resistance: 1000 series pure aluminum is more resistant to corrosion from the electrolyte inside the battery.
