Products Description
The battery current collector mainly uses metal foil, and the positive and negative collector of lithium-ion battery uses rolled aluminum foil and electrolytic copper foil respectively. The power battery requires safety, high conductivity and weight reduction, so the thickness of lithium copper and aluminum foil continues to shrink and the performance is constantly optimized.
