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 production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality. In addition, the different requirements of customers have also resulted in the waste of many intermediate products copper foil in manufacturing. The one-time input-output ratio is even less than 80%, and these copper foils have to be manufactured again, wasting resources.

At the same time of thinning, it is also necessary to improve the tensile strength, elongation and other indicators, otherwise it is easy to cause copper foil fracture, affecting the safety of the battery. Therefore, it is the general trend that the future use will be more light and meet the above indicators.

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.
