Product Description
What is Lithium Battery Foil
Aluminum foil used inside lithium batteries as a positive current collector. It is a key component of battery cells, located inside the battery and wound or stacked in the battery cell.
Function of Lithium Battery Foil
- Conductivity: Collects current generated by positive active materials (lithium cobalt oxide, lithium iron phosphate, ternary materials) and conducts it to the battery tab
- Support: Provides mechanical support as a substrate for positive active material coating
- Material: Typically single-layer plain foil made of pure aluminum or specific aluminum alloys
Advantages
- High Conductivity: Improves energy efficiency and reduces internal resistance
- High Purity: Minimizes side reactions caused by impurities
- Excellent Mechanical Properties: Superior tensile strength, elongation, and flexibility for various processes
- Surface Quality: Clean, flat, defect-free surface ensures good adhesion and conductive contact
- Thickness Uniformity: Extremely consistent thickness
- Corrosion Resistance: 1000 series pure aluminum resists electrolyte corrosion
