Product Details
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.
