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.

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.

Copper foil can be divided into calendered copper foil and electrolytic copper foil, which are mainly used for flexible printed circuits and other special purposes. In the production of clad laminates, a large number of applications are. As for the purity of copper, IEC-249-34 and Chinese standards stipulate that it shall not be lower than 99.8%.

The electrolyte contains oil, paint, grease, sediment and other contaminants attached to the surface of copper foil. After being squeezed by the squeezing (water) roller, the contaminants are squeezed flat, some contaminants attach to it, and some contaminants attach to the guide roller. Because the dirt is squeezed up during the operation, the dirt has a head and a tail, and has a direction.

Copper foil can also be divided into: single-sided treatment (single-sided hair), double-sided treatment (double-sided thick), smooth treatment (double-sided hair), double-sided light copper foil (double-sided hair) and very low profile copper foil (VLP copper foil) according to the surface condition. Post copper foil can be divided into electrolytic copper foil and calendered copper foil according to different production methods.
