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.

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.

If the rough surface and pinholes appear at the same time when there are stains on the rough surface, it indicates that the stains are caused by the dirty electrolyte, and the dirt is attached to the copper foil in the electrolytic cell. If there are stains on the rough surface, the copper foil is not rough and there are no pinholes, it means that the workshop production environment is dirty, the air contains dust, or other suspended impurities fall on the surface of the copper foil.

Foil making material requirements: the thinner the thickness is, the higher the quality grade is, and the lower the impurity content in the electrolyte is required. In order to ensure the quality, the purity of copper must be greater than 99.9%.

The commonly used reinforcement materials of copper clad laminate are alkali free (alkali metal oxide content shall not exceed 0.5%) glass fiber products (such as glass cloth, glass felt) or paper (such as wood pulp paper, bleached wood pulp paper, cotton wool paper). Therefore, laminates can be divided into glass cloth base and paper base.

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.
