Improved performance through development of new materials for lithium-ion batteries
UACJ Foil helps make batteries better by developing aluminum and copper foil materials and high-performance surfaces used in current collectors. These collectors are found in products such as lithium-ion batteries and electric double-layer capacitors.
Current collector foils
UACJ Foil’s aluminum and copper foils exhibit high strength, ductility, conductivity, heat-resistance and other advancements. We also strive to improve bendability, surface functionality (shaping, coating, etc.) and other characteristics.
