Double Side Shiny Copper Foil Thickness 4.5um 6um for Electric Vehicles Li-Ion Battery
Double-sided polished electrolytic copper foil is characterized by a symmetrical structure of two sides, metal density close to the theoretical density of copper, very low profile of the surface, excellent elongation and tensile strength, and so forth. As the cathode collector for lithium batteries, it has excellent cold/thermal resistance and can significantly extend the battery longevity. It can be widely applied in batteries for new-energy vehicles, the 3C industry represented by smart phones, notebook computers, and the ESS storage system, and space.
