Production process of electrolytic copper foil for transformer raw materials
2021-01-25
Copper foil is a key conductive material in lithium ion batteries and printed circuit boards. At present, most of our copper foils are used as anode materials for lithium ion batteries. With the development of lithium-ion batteries towards high capacity, thin, high-density and high-speed, copper foil is also moving towards ultra-thin and low profile (the surface roughness of copper foil is 2 μ M below), high strength, high ductility, etc
