Double-sided glossy foil that combines the advantages of both electrolytic foil and rolled foil.
A double-sided glossy foil that combines the advantages of both electrolytic foil (excellent crystal structure) and rolled foil (superior bending resistance) has transformed the concept of electrolytic copper foil. Leveraging this characteristic, it has received high praise as an electrode material for lithium-ion batteries and lithium-ion capacitors. Its ability to withstand expansion and contraction during repeated thermal history cycles during charging and discharging far surpasses that of rolled foil. The smoothness on both sides comparable to rolled copper foil, along with the unique crystal structure of WS foil, helps avoid breakage due to cracks. There is minimal thickness variation in both the width and length directions, allowing for long coils even with thin foil. Its compatibility with meter-width products contributes significantly to cost reduction. For more details, please contact us or refer to the catalog.
