The thin thickness electrolytic copper foil is the high-end copper foil.The width range of product is 100mm to 1300mm. The copper foil can effectively improve the energy density of lithium batteries and accord with the future trends of development of new energy vehicle power battery systems - Lightweight.
The Electrolytic copper foil have symmetric structure in double side.The density close to the copper theoretical density,extremely low surface profile, high elongation and tensile strength etc. Meanwhile, as the negative current collector of lithium batteries,the double-sided Electrolytic copper foil has good resistance to cold and thermal expansion, which can significantly extend the battery lifespan.
