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.

In order to improve the adhesion strength of copper foil to the substrate, Generally, oxidation (that is, after oxidation treatment, a layer of copper oxide or cuprous oxide is generated on the surface, which improves the bonding strength of the copper foil and the substrate due to the polarity) or roughening copper foil (using electrochemical methods to generate a layer of roughening layer on the surface of the copper foil, which increases the surface area of the copper foil, and improves the bonding strength of the copper foil and the substrate due to the anchoring effect of the roughening layer on the substrate) is used.

Copper foil is divided into calendered copper foil and electrolytic copper foil according to the preparation process, which accounts for the vast majority of the market. According to the Copper Foil Branch of China Electricity Association (CCFA), at present, domestic manufacturers mainly focus on the production of electrolytic copper foil. In 19 years, the domestic production capacity of electrolytic copper foil is expected to be close to 600000 tons, while that of rolled copper foil is only about 10000 tons.

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.

If the surface stain is caused by environmental problems, the cleaning and improvement of the air conditioning filter system should be strengthened, or the wind speed should be reduced, and the small hairs on the air conditioning filter bag must be completely removed. And the fibers and powders on the polymer materials must be completely removed, which are very easy to cause stains. The air supply pipeline is easy to use plastic material, which does not produce fiber and is easy to clean with water, acid and alkali.

Copper foil is a key conductive material in lithium ion batteries and printed circuit boards. It is a kind of negative electrolytic material, a thin, continuous metal foil deposited on the substrate of circuit board.
