We, JOVI, has exported the ED Copper foils for Li-ion Battery to the worldwide, USA, UK, Korea, India, Iran, Italy, Romania, Russia, Argentina, Peru... We can produce different thickness (from 9um to 35um ) and max width 1300mm. The double-shiney ED Copper foil has the characteristics of the tensile strength. It can distinctly reduce the contact resistance between the cathode current collector and the cathode material; the cathode current collector of the foil also has excellent resistance of the cold and heat expnsion, it can obviously increase the service life of the batteries.
