Copper foil is not a traditional metal copper product. It combines design concepts such as composite material and nano material technology, and different internal microstructures, resulting in different properties from traditional pure copper. The application of copper foil mainly focuses on the characteristics of conduction, heat conduction and electromagnetic wave shielding.

With the further competition in the market, even those with high added value have to be controlled from the production cost. Because the production requires very strict cleanliness of its electrolytic solution (copper sulfate solution), many filtration systems and liquid feeding pumps are repeatedly used in previous production processes. A new process flow is provided here, which can fundamentally control product quality and reduce production costs.

High end lithium battery copper foil needs to meet the requirements of high energy density, high safety, lightweight and other characteristics of power batteries, which is also the development trend of power batteries in the future. In order to meet the above characteristics, thinner lithium copper foil means smaller resistance, so the energy density and other performance of the battery will be improved. Moreover, the thinner the copper foil of lithium battery is, the lighter the weight of the corresponding battery will be.

The foil of the clad plate can be copper, nickel, aluminum and other metal foils. However, considering such factors as the conductivity, solderability, elongation, adhesion to the substrate and price of gold, it is considered appropriate except for special purposes.

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.
