The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

Copper foil can be divided into many kinds according to different classifications. According to the thickness, it can be divided into: thickness (more than 70 μ m) Regular thickness copper foil (more than 18 μ M but less than 70 μ m) Thin copper foil (more than 12 μ M but less than 18 μ m) Ultra thin copper foil (less than 12 μ m) Etc.

The adhesives used for the laminates mainly include phenolic, epoxy, polyester, polyimide, polytetrafluoroethylene resin, etc. Therefore, the laminates are also divided into phenolic, epoxy, polyester, polyimide, and polytetrafluoroethylene laminates.

Although the thickness of copper foil gradually becomes thinner, power battery manufacturers use 6 μ When the product is less than or equal to m, the coating machine, winding machine and other key equipment as well as the technological level cannot solve the problems such as wrinkles, belt breakage and high-temperature oxidation encountered in the production process, which leads to the inability to mass produce ultra-thin copper foil with high yield.
