According to the burning degree of the substrate in the flame and after leaving the ignition source, it can be divided into general type and self extinguishing type; According to the bending degree of the substrate, it can be divided into rigid and flexible laminates; According to the working temperature and working environment conditions of the substrate, it can be divided into heat resistant, radiation resistant, high-frequency foil clad plate, etc. In addition, there are also laminates used in special occasions, such as prefabricated inner laminates, metal based laminates, and copper foil, nickel foil, silver foil, aluminum foil, Kang copper foil, beryllium copper foil laminates according to the type of foil.

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.

Electrolytic copper foil is made by dissolving copper into copper sulfate solution, electrodepositing the copper sulfate electrolyte under the action of direct current in special electrolytic equipment to make the original foil, and then carrying out surface treatment, heat-resistant layer treatment, oxidation prevention treatment and other surface treatment processes on the original foil according to customer requirements.

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.
