The production of extremely thin copper foil has high barriers, and the products produced still need to meet many requirements of downstream lithium ion battery manufacturers. For investors, they should not only focus on the single index of thickness, not all manufacturers produce 6 μ M Copper foil is consistent, and the thinner the better.

The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

Calendered copper foil products have good ductility, flexibility, low roughness and high folding resistance, and have become the basic materials of flexible printed circuit boards, mainly used in flexible circuit boards and high-frequency circuit boards.

During the production of copper foil, tiny foreign matters are adhered on the surface to form spots with different colors from the surface, which are called stains. Judgment method: use macroscopic inspection to judge whether it is a waste product, a secondary product or a finished product according to the number and area of stains and the impact on product quality.

The technical feature of electrolytic copper foil is that various technical conditions in electrolyte and additives must be strictly controlled, so equipment alone is not enough to produce high-performance copper foil; High performance has high requirements for the materials of anode plate and cathode roll in the raw foil equipment, the processing accuracy and consistency of the equipment; In the production process, the concentration of copper and acid in the electrolyte needs to be monitored and adjusted in real time.
